If you follow the instructions on the seatpost, they have you adjust your seat a bit forward and post a bit up, so that when you sit on it with a correctly tuned spring the sag puts you in your perfect position. Then it doesn't move much to either side of that, and only when it's actively absorbing a bump. If you're the kind of person that is put off by your position moving a few millimeters then sure it'll be annoying, but it shouldn't be for most people, once set up correctly. Though I've only tried the seatpost, not both at the same time

I have had lower back surgery for ruptured discs and have been using a suspension seat post for the last fifteen years. The seat post has allowed me to continue riding, I would definitely recommend one for someone with lower back problems.
For longer rides they're great. I have Canyon's VCLS leaf sprung seatpost which is a brilliant alternative and definitely worth considering. It's quite expensive but they are less than half the weight of the Redshift and look a lot sleeker.
I have an S13 (VCLS 1.0) seatpost on my Inflite and am always amazed how compliant it is despite looking like a regular post. Also a quite a bit cheaper than the S14.
I have a similar one with no set back, I haven't found it much different to the seat post I was running (sadly...) but I'm going to try one with a 20mm setback. I reckon these are a great compromise between wanting a bit more compliance but as much as these offer.
I've had the Redshift on for about three years now and going back to a rigid stem just isn't an option. It's soooo much better on rough terrain and takes the buzz out on the road as well. I had the same epiphany as Jimmy a few years ago. I'm faster, but more importantly have more fun, when I'm comfortable. And since we've determined that weight doesn't matter, the slight penalty just isn't relevant.
i have the stem and seatpost on my gravel bikes and was even thinking about adding the stem to my TCR. i guess it may be a little blasphemous to add suspension to a super stiff race bike but the added comfort is worth it.
Go on a long bumpy ride without the suspensions and with them for a couple of times. You will feel that how much more gas you save up in the tank by reducing the vibration fatigue. I was able to go twice as much as before thanks to this. You guys said that the saddle position will change, and that is in the manual. It states that you have a 6 mm initial sag so you have to calculate with that. My only issue is with the stem. You have to check the elastomer tension time to time as the bolt that puts the tension on the elastomers tend to loosen after a couple of rough rides. It will feel softer initially, but it hits you on a descent when you are cornering. I almost learned how to fly, when the dam thing loosened up and the characteristics of the steering changed. It felt like hitting a pothole when I put my weight on the front. Other than that, it was my best bike upgrade so far.
@@johnnunn8688 If you follow the pre-load procedure, than the initial sag should be the same for every rider, independent of their weight. Unless they are over the max pre-load capacity.
I’ve had the Redshift Shopstop stem + seatpost combo for a few years on my gravel bike and although no lightweight items they make for a super comfy ride without the hassle of “real” suspension.
I put Redshift stem and post on my Winter bike that i do Paris Roubaix on every year, they were a game changer, never been more comfortable on the cobbles, well worth the dosh!
For 5 months on my solo trip I've been using eeSilk from Cane Creek. I can't imagine riding without it now. It's expensive but no saddle sores after few thousand kilometers. Also I'm a proud owner of Redshift suspension stem which at beginning felt kind of weird. Especially with an Ortlieb Handlebar bag, but I've got used to it. And again I can highly recommend. No wrist pains after 70-80km a day.
@@rickeverett3304 I'd agree with that assessment. Pretty sure the eesilk, especially in the carbon variant, is quite a bit lighter though. If that's actually important to someone
I have the Redshift seatpost and stem ,the standard versions... Maybe try changing the elastomers in the stem to firm up the handlebars! Also may suggest trying them on an aluminium or steel gravel bike, might make all the difference.
I have the original post with the springs, and I love it. Honestly, I wouldn't swap to the elastomer version. Sure, you save a few grams. But the springs are really easy to adjust and get things just right. The proof is that I just forget its there most of the time. Btw: I'd consider the stem, but my bike has a Cannondale silk road headshock, so I'm good on that fro nt. Cheers
Yeah you have to add greater resistance to the stem for road bikes because of the added weight to the front vs a gravel/touring bike. I think the weight guidelines in the manual are more for gravel/touring.
I had the same issue with the stem moving too much and feeling like you would tip forwarded. However, I just added the firmer elastomer and now it's perfect. When I'm out of saddle or break hard it doesn't move much, but it moves enough to take a long of the road/trail buzz out. Also absorbs and takes the edge off the big bumps. Really love their system.
@@michaelfisher9760 really good. Im a heavy rider at 115kg, so I use the stiffest polymers. Run 25mm tyres at 100psi, so get quite a harsh ride normally. Used to suffer from hand numbness on longer rides. That's pretty much gone now. Just sucks up the road noise.
I've had the Redshift stem for about year and half now on my steel gravel bike and I absolutely love it. It does take the sting out of some heavier hits and in general makes me feel more confident when descending or when on fast chunky segments. It doesn't bob when out of the saddle either!
I've been using the stem and another brand seatpost for a couple of years on my gravel bike. With 650b wheels and bigger tires I can tackle some pretty gnarly conditions. Game changer.
For the stem, I found that when I used recommended elastomers from the instructions it was a little bit too squishy. If you add just a little bit more, to increase the stiffness, may improve the feel. I did this, and I barely notice the stem when riding smooth the road, but as soon as anything gets chunky, it, absorbs it all up.
The redshifts were on my radar then I forgot about them and now you have reminded me again. Thanks. I'm guessing you need to set the saddle up a bit higher so when you sit on it, the sag takes it to your actual bikefit height. Not sure what you can do about the stem though. Maybe if there is one that has a rubber insert for vibration dampening rather than suspension, so it doesn't move around so much.
I have both on two of my bikes and love them. Taking the time to experiment and get the setup to your liking is key. I have the seatpost setup so that there is barely no sag (unless I'm carrying extra water or other stuff). That way it keeps the same/normal geometry on smooth roads, and soaks up all the bumps and rough stuff. I have the stem setup so that it is very stiff in the drops, at the brink of sag on the bar tops, and a tiny bit of sag when on the brake hoods (this is possible because drop bars have different leverage at those points). This gives me the best of all worlds for sprinting, control, and comfort.
aren't you supposed to set them up for your normal saddle height accounting for the sag? so, if it sags 10%, then your your usual saddle height should be plus that 10%?
Manon Lloyd from GCN used these products for a UCI gravel worlds qualifier and gave it a thumbs up. Maybe you should set the saddle height up to compensate for the sag or set the spring preload so that It doesn’t sag under your weight just sitting on the saddle. If you have sag you’re reducing the suspension travel. It looks like a cool product. I’d like to try it.
I have the Pro stem, very satisfied so far. I decided not to go for the seat post as my GT Grade has kind of a built in suspension, thanks to those glass-fiber rods having a lot of travel, and feels comfy enough but might still change my mind one day.
I have GT carbon grade. Yes the 25mm of travel works on a frame that's less than a kilo. I have read a flex seat post doesn't really have any benefit. For the bars I went for Bontrager carbon with gel inserts rather than a stem. Also Maxxis 120 tpi 40mm tyres are so subtle!
I have the suspension seatpost from Decathlon. The spring it comes with is very hard, and it doesn't provide that much comfort. You can adjust the preload, but even on the lowest possible, it's not doing much. I ended switching it with a Cube RFR Suspension Seatpost. It's more plush and comfortable (they have 2 versions, for riders 60-90 Kg and 80-120 Kg). And it looks much better than the Decathlon one. The only issue with these seatposts is their weight, I think they are well over 500g. But I prefer being comfortable.
I’ve got the stem suspension on my Cannondale Topstone 1 gravel bike and the seatpost suspension on my Giant Tallon Zero mtb and after a bit of juggling, now have both of them perfectly adjusted. I ordered a softer spring for the seatpost as at 70 kgs I found that the standard one was too hard. I’m 71 and the difference these two items have made to my riding comfort is immeasurable. Both easy to fit and adjust. Great video from you guys as usual.
I have the Redshift Pro Shockstem on both my road bikes (12 months). I ride mainly sealed rural country roads in Australia and they can be quite uneven and rough. The shockstem Pro takes the vibration out of the handlebars going over rough surfaces which then doesn't travel up through your arms, shoulders and neck which can often fatigue. You can adjust the movement of the stem by selecting the correct combination of rubber blocks inserted in the stem to match your weight. 5 Star rating from me.
ive been using the pro stem on my gravel/winter bike and its a revelation. After doing the King Alfreds way and having numb hands afterwards i thought i would try this in order to reduce hand fatigue, and hay presto, it does what says on the tin. You just have to try various elastomer combinations, i went for a harder elastomer which reduces bob but still gives enough suspension to remove hand fatigue. The seat post is also to be tried but not sure if it will rub on my Tailfin rear aero pack if on a bike packing trip. The conclusion is that it works and definitley worth trying out, especially on gravel rides or rough rough surfaces.
You need to remember that the seat post doesn’t just compress in line with the post, it also moves back, which reduces the amount of effective drop in relation to your pedals. You’ll still be closer, but not as much as you think. These sort of things have been around for ages in mountain biking, before rear suspension got good, so some of us old folk have gone through this discovery and figuring out geometry a long time ago. 😊
Yeah, the 10 cm travel CaneCreek posts really did the trick when a suspension frame was too costly or complex. It's funny that roadies now consider 28 mm normal, but they'd gather to shame me if I'd turn up to a club crit with 28s. I did a club crit on 28mm Diamond Tufo cross thingies and they all just shook their "wise" heads. Fat tyres just work for cyclists. It's becoming the norm in city bikes as well, that used to be skinny tyres with crappy suspension forks.
I dunno, I did a bit of research and I came up with the combination of a Cane Creek eeSilk seatpost and a Cirrus Kinekt stem and it all works AMAZING with my aluminum (or: aluminium for you Brits) framed gravel bike (Marin Gestalt - not 1, or X, or whatever - just the base model). The seatpost has little to no "sag", while the stem does have a fair amount if you "lean in" too much (but the handlebar doesn't pitch forward like the one you used, as it uses a parallelogram design to prevent that). The setup is almost unnoticeable UNTIL you get into the "rough stuff". As much damping as possible for as little travel as is necessary. Works... I would suggest you revisit this.
the specialized terra seatpost that comes stock on the crux is a good medium between this and a rigid post. I put one on my bike and it's added a noticeable amount of smoothness on gravel and rough paved surfaces. It looks just like a normal seatpost as well.
If it's that hard to know if there's a fit problem, then there isn't really a fit problem. Not one anyone should care about anyway. More comfortable = good thing. Self flagellation went out with 23s.
I weigh 100kg but set the elastomers in the stem for an 80kg rider which seems to work better, the other Redshift product I would recommend is the Cruise Control top grips.
Thanks for the video. Interesting as usually these components are tested on gravel bikes. Which make me think about my main doubt about buying one. Is it worth it if you already have a gravel bike with pretty generous clearance (50 mm). Or could I have the same comfort just by lowering my tires pressure without sacrificing weight and fitting.
I run the EESILK seatpost on my road bike and rthe EESILK gravel seatpost on my gravel bike. Great pieces of kit. Waiting for the 70mm EESILK stem to be sold in the EU. 80mm redshift stem is 10mm too long for me.
remember when Girvin Flex Stem came out. Given how still road bikes are a suspension stem will take the sting out of the road. Problem with that stem is what you alluded to. parallelogram stems solve that issue
Why am I riding my road bike on gravel? I wouldn't take my Tesla (POS) offroad. Just set the seat post up 1cm higher than. 69......oh yeah. So, it's .5cm off now and again.
I had a cheap suspension post on my old commuter bike. It worked a treat and was about £15. I've recently got a road bike after years of not cycling and love the efficiency and low rolling resistance. It ain't comfy though.
What about the SR Suntour SP12-NCX Suspension Seat Post? it seems to work the same way (parallelogram), claims the same weight, but it's way cheaper...
As a disabled cyclist with shoulder & back issues, with out suspension I couldn't ride. I've run air sprung forks on my MTB for years and have suspension seat post & 50mm travel fork on my gravel bike. It makes long rides less fatigue inducing. Years ago both Girvin & Allsop experimented with these systems. The Allsop was hugely ugly!
I have the Redshift stem and love it on my gravel bike. I've pondered the seat post for a while but think after your initial thoughts I might just get it and see how I get on. Its certainly an interesting concept.
Go for it. I scored the regular one (springs) second hand but nearly new, and it's one of my best buys ever. I reckon it's still worth it at full price.
Noob...suspension makes grip more reliable. Lower peak loads, not just on your hands and bum, but also for the tyres pressing the surface. On MTB's, suspension bikes get away with more tyre pressure, not just for comfort, but also grip.
One of the things I see is because the seat moves back a little on bumps instead of just down, the distance between your seat and pedals probably doesn't change much. It will change your knee angle slightly though. Every review I've been looking up hasn't mentioned it being an issue... I think I'm gonna get one for my hardtail MTB.
New Jimmy product rating system ; ‘not a heap of sh#%’. Praise indeed Jimmy. Quality review. How about old school saddle with springs to test, with a mahoosive comedy Carradice saddle bag for sandwiches and ginger beer?
I’m enjoying the bike so far ua-cam.com/users/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA My only real complaints are the brakes and the pedals. I feel like a bike designed for bigger people should have much larger pedals and more heavy duty brakes. I’ve only gotten two really good rides out of it, minimal downhill action, and the brakes feel like they’re already going out. A larger person has more momentum, so I think this wasn’t thought through very well. Also, I wear size 13-14 wide shoes. My feet cramp up on these pedals that are clearly made for smaller feet. Since I’m not a pro rider (and I don’t think many are who purchase this bike) I don’t think that the straps on the pedal are necessary at all. None of this takes away from the enjoyment I get from riding, however. I’ll just head to a bike shop to improve on a few things.
My seat post broke. The suspension stem turn out to have a play that does a 2 or 3 mm difference at the end of the handlebar. I guess I got a fake products. I also was at the bottom of the seatpost with both spring. This does not occur, right?
I bought alloy Cane creek eesilk for commuter bike 2 years ago. After few months I bough CF eesilk for gravel bike. Very expensive but my ass thanking my wallet on every ride. I can ride cobblestone in the saddle without any discomfort.
My brother swears by his Specialized Future Shock and won't accept a bike that doesn't have something at least as good. I've looked this Redshift system for a while, but am leaning more towards RockShox suspension seatpost.
Perfect *haha* we as mtb riders had the same thoughts in the 90s. Your roadie guys can overjump the last 20 years of bike evolution and go direct to a xc mtb. Than you have skinny nobby tires, small disk breaks, low travel forks and if you want to a rear shock...... just smash on your dumb bent bars and you are ready....... shock seat posts.. omg ridiculous....
Every bump is just a small hill. The less of the bike has to go over that hill, the less forward momentum you lose. And the heaviest part of the bike, by far, is the rider. It's not just comfort making you go faster. The comfort just means that the bike is going over all those small hills, but you're not. Your mass can continue on a more straight path. Suspension actually makes you a LOT faster. I'm surprised road bikes don't have it, cus no way is the tyre enough on rough asphalt, for example. The kind that makes you vibrate. To make an 80kg pereson vibrate, takes a lot of energy. And it all comes out of your legs to make you vibrate up and down, instead of moving forwards. But why the seatpost and bars? Just put it in the forks like people have been doing for decades.
Ergon has the CF post for 10 years. Canyon put it on their bikes, naming it VCLS 2.0 Unlike this post, VCLS does not change the seatpost length, the distance to the bottom bracket. It is also lighter.
I had one on a commute bike but recently switched it to my gravel for longer rides. I have lower back issues, and it has really helped. However, I found it hard to set up with 100km+ rides, causing me some issues on my right hamstring that I can't resolve with height or position adjustments. So, I am still not sure it's ideal for ride position given the sag, and I am a heavy rider.
I've had the Redshift stem on my road bike for 4 years. The gravel bike doesn't get out much these days! You get used to the dip pretty quickly and it's worth it for the comfort on the deplorable uk rural road surfaces.
I did the badger divide last May and couldn’t feel my hands for a month afterwards… got the redshift stem afterwards and game changer…. Cuts a load of the vibrations out. Don’t have the seat post but use a Brooks cambium cut out which has a decent amount of give (although always a worry that a wardrobe malfunction could be v painful 😮). Chur 🤙
In theory if you set it up so your seat height is correct while you’re sat on the bike on level ground then I don’t see an issue with your seat moving by a couple of cm’s given that it should be almost immediately returning to neutral and presumably that would only be for the biggest of bumps anyway, with your typical imperfect road surface resulting in a much smaller deflection. It’s all a moot point for me anyway as neither my road bike or gravel bike have round seat posts!
My bike commute has some real choppy bits, and a lot of gravel on pavement. These are some of the most expensive components on my bike, I’ve had them a couple years, and they’ve been totally worth it. Just soaking up the biggest hits makes a huge difference in quality of life. Any health loss in bike fit has to made up by not having the bones rattled, I assume. I didn’t realize these had gotten popular though, May upgrade my seat post ring to locking.
A spring loaded saddle will literally give you more traction, as the bike will be able to follow the ground structure if it isn’t rigidly connected to your bones
You can adjust the height to be pretty much the same. Also, I doubt having the geometry change in such small amounts would do any harm to you long term. How many people have their seat heights adjusted "perfectly" in the first place? Moreover, instead of transferring potholes and bumps straight into your ass and spine, the suspension should put less strain and shock into your joints. Less jolts and you said it felt more comfortable. You're body will tell you and if you noticed that difference im sure long term it would appreicate it.
Its a shame most road bikes now have propriety seat posts that aren't round. Only allows this product work for the select few, like the specialized aethos. Bloody bike brands making road bikes parts non interchangeable unless its there brand!
It will be the next revolution in road bike tech that is for certain. Once they stop relying on the pneumatic tyer to do the job you/we will all be faster on the bike that's for sure. It is exactly the same principle as it is for mountain bikes but with high frequency rather than low. road bikes need suspension just like every other vehicle. 15mm would do the job
Just set the seat height and fore-aft with taking the sag into account (little bit higher than usual and slightly forward). Not sure about the stem though. My guess is that a stem spacer will do a similar thing to set your bar height back to the one recommended during bike fitting. As for the reach, it depends on how do you mount the stem (positive or negative drop), but I'm sure you can also mitigate that by adjusting the position of brake levers / shifters.
redshift suspension seatpost works well on my gravel bike, stern is ok but it sometimes move the body downward & slightly rotate your hands when it pivots i had seen others recommending the Vecnum Freeqence stern,
Always had a suspension seat post on my touring bike. New bike, no sus. I miss it and have realised, after hundreds of miles, that's why the comfort has gone. Adds a fair bit of weight but the trade off for touring is worth it.
Ive used the Red Shift stems on road and gravel bikes since they came out. Too many hand surgeries . They made a difference with 2 layers of padded tape.. MAy try a seat one on a gravel bike. Some monster holes in the shade on country road thanks for the videos
Yeah I have four of these seat posts and two of those stems. I honestly don't think I could go back to riding without them. RedShift is that good shit, there Arc Light pedals are another product worth there weight in gold.
Did you actually get around to testing the decathlon seat post? I couldn’t work it out from the video. I thought you had but then you a-pear at the end of the video saying they are sold out.
I've got the red shift seat post on my gravel bike specialized comp E5 and pared with a good seat it's really good. I have no discomfort at all after a ride.
Why would people think that this is shite? I had a bike when i was a kid that had springs on the saddle, and it was quite comfortable on not-so-perfect roads and it's simpler than this contraption.
It's an interesting idea, however I wouldn't trust the stem, a little change in the hoods angle can easily and unpredictably cause your hands to slip off the hoods, causing a serious accident.
Hi guys, love your show and all the gags😅 Anyhow down to business. The trick is on the Redshift or the NCX which I use the latter is you adjust the preload as to make the seatpost virtually rigid. That way it will only flex when you need it to instead of your back doing the flexing and your reach will stay the same. On the NCX you can also grind the back of the seatpost away so that it will fit into a D-shape seat tube which was a must for my well used back The Redshift stem in my opinion should be mandatory for safety Cheers Scott
I’ve been looking into these to relieve back pain from a herniated disk. Have a buddy who got it and it relieves a bit of the shock pressure to his spine.
I have used the Redshift seat post since i sponsored their GoFundMe and have tried them on both road (where it lives) and on hard tail mountain bikes. Still find it a must have.

I put Redshift stem and post on my Winter bike that i do Paris Roubaix on every year, they were a game changer, never been more comfortable on the cobbles, well worth the dosh!
For 5 months on my solo trip I've been using eeSilk from Cane Creek. I can't imagine riding without it now. It's expensive but no saddle sores after few thousand kilometers. Also I'm a proud owner of Redshift suspension stem which at beginning felt kind of weird. Especially with an Ortlieb Handlebar bag, but I've got used to it. And again I can highly recommend. No wrist pains after 70-80km a day.
The eesilk is the top of my wanted list...
@@markjthomson I have an EESilk on one bike and the Redshift on my #2 and wifes bikes, both are good but the Redshift is more comfortable
@@rickeverett3304 I'd agree with that assessment. Pretty sure the eesilk, especially in the carbon variant, is quite a bit lighter though. If that's actually important to someone
I have the Redshift seatpost and stem ,the standard versions... Maybe try changing the elastomers in the stem to firm up the handlebars! Also may suggest trying them on an aluminium or steel gravel bike, might make all the difference.
I have the original post with the springs, and I love it.
Honestly, I wouldn't swap to the elastomer version. Sure, you save a few grams. But the springs are really easy to adjust and get things just right.
The proof is that I just forget its there most of the time.
Btw: I'd consider the stem, but my bike has a Cannondale silk road headshock, so I'm good on that fro nt.
Cheers
Yeah you have to add greater resistance to the stem for road bikes because of the added weight to the front vs a gravel/touring bike. I think the weight guidelines in the manual are more for gravel/touring.
Wife and I really like our Redshift stems, may have to give the seat posts a try as well.
Didn't Girvin make the flex stem 20 years ago or so? Had one on my proflex MTB. The more things change......
I had the same issue with the stem moving too much and feeling like you would tip forwarded. However, I just added the firmer elastomer and now it's perfect. When I'm out of saddle or break hard it doesn't move much, but it moves enough to take a long of the road/trail buzz out. Also absorbs and takes the edge off the big bumps. Really love their system.
I love my redshift stem. Would never go back now.
I have a Redshift stem too and love it too! Wouldn’t dream of going without it now.
How is it with general road vibrations rather than just pot holes?
@@michaelfisher9760 really good. Im a heavy rider at 115kg, so I use the stiffest polymers. Run 25mm tyres at 100psi, so get quite a harsh ride normally. Used to suffer from hand numbness on longer rides. That's pretty much gone now. Just sucks up the road noise.
I've had the Redshift stem for about year and half now on my steel gravel bike and I absolutely love it. It does take the sting out of some heavier hits and in general makes me feel more confident when descending or when on fast chunky segments. It doesn't bob when out of the saddle either!
I've been using the stem and another brand seatpost for a couple of years on my gravel bike. With 650b wheels and bigger tires I can tackle some pretty gnarly conditions. Game changer.
For the stem, I found that when I used recommended elastomers from the instructions it was a little bit too squishy. If you add just a little bit more, to increase the stiffness, may improve the feel. I did this, and I barely notice the stem when riding smooth the road, but as soon as anything gets chunky, it, absorbs it all up.
The redshifts were on my radar then I forgot about them and now you have reminded me again. Thanks. I'm guessing you need to set the saddle up a bit higher so when you sit on it, the sag takes it to your actual bikefit height. Not sure what you can do about the stem though. Maybe if there is one that has a rubber insert for vibration dampening rather than suspension, so it doesn't move around so much.
I have both on two of my bikes and love them. Taking the time to experiment and get the setup to your liking is key. I have the seatpost setup so that there is barely no sag (unless I'm carrying extra water or other stuff). That way it keeps the same/normal geometry on smooth roads, and soaks up all the bumps and rough stuff. I have the stem setup so that it is very stiff in the drops, at the brink of sag on the bar tops, and a tiny bit of sag when on the brake hoods (this is possible because drop bars have different leverage at those points). This gives me the best of all worlds for sprinting, control, and comfort.
aren't you supposed to set them up for your normal saddle height accounting for the sag? so, if it sags 10%, then your your usual saddle height should be plus that 10%?
Manon Lloyd from GCN used these products for a UCI gravel worlds qualifier and gave it a thumbs up. Maybe you should set the saddle height up to compensate for the sag or set the spring preload so that It doesn’t sag under your weight just sitting on the saddle. If you have sag you’re reducing the suspension travel. It looks like a cool product. I’d like to try it.
Actually, GCN gets paid to give a thumbs up for the product that is being ‘displayed’ in a video.
I have the Pro stem, very satisfied so far. I decided not to go for the seat post as my GT Grade has kind of a built in suspension, thanks to those glass-fiber rods having a lot of travel, and feels comfy enough but might still change my mind one day.
I have GT carbon grade. Yes the 25mm of travel works on a frame that's less than a kilo. I have read a flex seat post doesn't really have any benefit. For the bars I went for Bontrager carbon with gel inserts rather than a stem. Also Maxxis 120 tpi 40mm tyres are so subtle!
@@SimonCurrey what a great bike we have! 😉
I have the suspension seatpost from Decathlon. The spring it comes with is very hard, and it doesn't provide that much comfort. You can adjust the preload, but even on the lowest possible, it's not doing much.
I ended switching it with a Cube RFR Suspension Seatpost. It's more plush and comfortable (they have 2 versions, for riders 60-90 Kg and 80-120 Kg). And it looks much better than the Decathlon one.
The only issue with these seatposts is their weight, I think they are well over 500g. But I prefer being comfortable.
I’ve got the stem suspension on my Cannondale Topstone 1 gravel bike and the seatpost suspension on my Giant Tallon Zero mtb and after a bit of juggling, now have both of them perfectly adjusted. I ordered a softer spring for the seatpost as at 70 kgs I found that the standard one was too hard. I’m 71 and the difference these two items have made to my riding comfort is immeasurable. Both easy to fit and adjust. Great video from you guys as usual.
7:07, read the manual...
I have the Redshift Pro Shockstem on both my road bikes (12 months). I ride mainly sealed rural country roads in Australia and they can be quite uneven and rough. The shockstem Pro takes the vibration out of the handlebars going over rough surfaces which then doesn't travel up through your arms, shoulders and neck which can often fatigue. You can adjust the movement of the stem by selecting the correct combination of rubber blocks inserted in the stem to match your weight. 5 Star rating from me.
Great Video as always! You should try out the Ergon one with the leaf spring design :)
ive been using the pro stem on my gravel/winter bike and its a revelation. After doing the King Alfreds way and having numb hands afterwards i thought i would try this in order to reduce hand fatigue, and hay presto, it does what says on the tin. You just have to try various elastomer combinations, i went for a harder elastomer which reduces bob but still gives enough suspension to remove hand fatigue. The seat post is also to be tried but not sure if it will rub on my Tailfin rear aero pack if on a bike packing trip. The conclusion is that it works and definitley worth trying out, especially on gravel rides or rough rough surfaces.
You need to remember that the seat post doesn’t just compress in line with the post, it also moves back, which reduces the amount of effective drop in relation to your pedals. You’ll still be closer, but not as much as you think. These sort of things have been around for ages in mountain biking, before rear suspension got good, so some of us old folk have gone through this discovery and figuring out geometry a long time ago. 😊
Yeah, the 10 cm travel CaneCreek posts really did the trick when a suspension frame was too costly or complex.
It's funny that roadies now consider 28 mm normal, but they'd gather to shame me if I'd turn up to a club crit with 28s. I did a club crit on 28mm Diamond Tufo cross thingies and they all just shook their "wise" heads. Fat tyres just work for cyclists. It's becoming the norm in city bikes as well, that used to be skinny tyres with crappy suspension forks.
I dunno, I did a bit of research and I came up with the combination of a Cane Creek eeSilk seatpost and a Cirrus Kinekt stem and it all works AMAZING with my aluminum (or: aluminium for you Brits) framed gravel bike (Marin Gestalt - not 1, or X, or whatever - just the base model). The seatpost has little to no "sag", while the stem does have a fair amount if you "lean in" too much (but the handlebar doesn't pitch forward like the one you used, as it uses a parallelogram design to prevent that). The setup is almost unnoticeable UNTIL you get into the "rough stuff". As much damping as possible for as little travel as is necessary.
Works...
I would suggest you revisit this.
the specialized terra seatpost that comes stock on the crux is a good medium between this and a rigid post. I put one on my bike and it's added a noticeable amount of smoothness on gravel and rough paved surfaces. It looks just like a normal seatpost as well.
If it's that hard to know if there's a fit problem, then there isn't really a fit problem. Not one anyone should care about anyway.
More comfortable = good thing. Self flagellation went out with 23s.
I weigh 100kg but set the elastomers in the stem for an 80kg rider which seems to work better, the other Redshift product I would recommend is the Cruise Control top grips.
Thanks for the video. Interesting as usually these components are tested on gravel bikes. Which make me think about my main doubt about buying one. Is it worth it if you already have a gravel bike with pretty generous clearance (50 mm). Or could I have the same comfort just by lowering my tires pressure without sacrificing weight and fitting.
I run the EESILK seatpost on my road bike and rthe EESILK gravel seatpost on my gravel bike. Great pieces of kit. Waiting for the 70mm EESILK stem to be sold in the EU. 80mm redshift stem is 10mm too long for me.
remember when Girvin Flex Stem came out. Given how still road bikes are a suspension stem will take the sting out of the road. Problem with that stem is what you alluded to. parallelogram stems solve that issue
Thank you for the informative video.
However: the background music is distracting and it's generally superfluous
Why am I riding my road bike on gravel? I wouldn't take my Tesla (POS) offroad. Just set the seat post up 1cm higher than. 69......oh yeah. So, it's .5cm off now and again.
I had a cheap suspension post on my old commuter bike. It worked a treat and was about £15. I've recently got a road bike after years of not cycling and love the efficiency and low rolling resistance.
It ain't comfy though.
What about the SR Suntour SP12-NCX Suspension Seat Post? it seems to work the same way (parallelogram), claims the same weight, but it's way cheaper...
Suntour NCX has also similar product whcih got lot of praise and is even much more cheaper.
As a disabled cyclist with shoulder & back issues, with out suspension I couldn't ride. I've run air sprung forks on my MTB for years and have suspension seat post & 50mm travel fork on my gravel bike. It makes long rides less fatigue inducing. Years ago both Girvin & Allsop experimented with these systems. The Allsop was hugely ugly!
I have the Redshift stem and love it on my gravel bike. I've pondered the seat post for a while but think after your initial thoughts I might just get it and see how I get on. Its certainly an interesting concept.
Go for it.
I scored the regular one (springs) second hand but nearly new, and it's one of my best buys ever. I reckon it's still worth it at full price.
Noob...suspension makes grip more reliable. Lower peak loads, not just on your hands and bum, but also for the tyres pressing the surface. On MTB's, suspension bikes get away with more tyre pressure, not just for comfort, but also grip.
One of the things I see is because the seat moves back a little on bumps instead of just down, the distance between your seat and pedals probably doesn't change much. It will change your knee angle slightly though. Every review I've been looking up hasn't mentioned it being an issue... I think I'm gonna get one for my hardtail MTB.
New Jimmy product rating system ; ‘not a heap of sh#%’. Praise indeed Jimmy. Quality review. How about old school saddle with springs to test, with a mahoosive comedy Carradice saddle bag for sandwiches and ginger beer?
I’m enjoying the bike so far ua-cam.com/users/postUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA My only real complaints are the brakes and the pedals. I feel like a bike designed for bigger people should have much larger pedals and more heavy duty brakes. I’ve only gotten two really good rides out of it, minimal downhill action, and the brakes feel like they’re already going out. A larger person has more momentum, so I think this wasn’t thought through very well. Also, I wear size 13-14 wide shoes. My feet cramp up on these pedals that are clearly made for smaller feet. Since I’m not a pro rider (and I don’t think many are who purchase this bike) I don’t think that the straps on the pedal are necessary at all. None of this takes away from the enjoyment I get from riding, however. I’ll just head to a bike shop to improve on a few things.
My seat post broke. The suspension stem turn out to have a play that does a 2 or 3 mm difference at the end of the handlebar. I guess I got a fake products. I also was at the bottom of the seatpost with both spring. This does not occur, right?
I bought alloy Cane creek eesilk for commuter bike 2 years ago. After few months I bough CF eesilk for gravel bike. Very expensive but my ass thanking my wallet on every ride. I can ride cobblestone in the saddle without any discomfort.
My brother swears by his Specialized Future Shock and won't accept a bike that doesn't have something at least as good. I've looked this Redshift system for a while, but am leaning more towards RockShox suspension seatpost.
Perfect *haha* we as mtb riders had the same thoughts in the 90s. Your roadie guys can overjump the last 20 years of bike evolution and go direct to a xc mtb. Than you have skinny nobby tires, small disk breaks, low travel forks and if you want to a rear shock...... just smash on your dumb bent bars and you are ready....... shock seat posts.. omg ridiculous....
Every bump is just a small hill. The less of the bike has to go over that hill, the less forward momentum you lose. And the heaviest part of the bike, by far, is the rider. It's not just comfort making you go faster. The comfort just means that the bike is going over all those small hills, but you're not. Your mass can continue on a more straight path. Suspension actually makes you a LOT faster. I'm surprised road bikes don't have it, cus no way is the tyre enough on rough asphalt, for example. The kind that makes you vibrate. To make an 80kg pereson vibrate, takes a lot of energy. And it all comes out of your legs to make you vibrate up and down, instead of moving forwards.
But why the seatpost and bars? Just put it in the forks like people have been doing for decades.
Ergon has the CF post for 10 years. Canyon put it on their bikes, naming it VCLS 2.0
Unlike this post, VCLS does not change the seatpost length, the distance to the bottom bracket. It is also lighter.
Back over the pond you go and try it across the states :)
other than recently / purposely-built greenways, road riding in the USA is getting more like Roubaix (w/o the romance of history) every day.
I had one on a commute bike but recently switched it to my gravel for longer rides. I have lower back issues, and it has really helped. However, I found it hard to set up with 100km+ rides, causing me some issues on my right hamstring that I can't resolve with height or position adjustments. So, I am still not sure it's ideal for ride position given the sag, and I am a heavy rider.
I've had the Redshift stem on my road bike for 4 years. The gravel bike doesn't get out much these days! You get used to the dip pretty quickly and it's worth it for the comfort on the deplorable uk rural road surfaces.
I did the badger divide last May and couldn’t feel my hands for a month afterwards… got the redshift stem afterwards and game changer…. Cuts a load of the vibrations out. Don’t have the seat post but use a Brooks cambium cut out which has a decent amount of give (although always a worry that a wardrobe malfunction could be v painful 😮). Chur 🤙
SR SUNTOUR New SP12-NCX ,I've been using one of these for over 2 years. It's a Godsend for my back
In theory if you set it up so your seat height is correct while you’re sat on the bike on level ground then I don’t see an issue with your seat moving by a couple of cm’s given that it should be almost immediately returning to neutral and presumably that would only be for the biggest of bumps anyway, with your typical imperfect road surface resulting in a much smaller deflection. It’s all a moot point for me anyway as neither my road bike or gravel bike have round seat posts!
My bike commute has some real choppy bits, and a lot of gravel on pavement. These are some of the most expensive components on my bike, I’ve had them a couple years, and they’ve been totally worth it. Just soaking up the biggest hits makes a huge difference in quality of life. Any health loss in bike fit has to made up by not having the bones rattled, I assume. I didn’t realize these had gotten popular though, May upgrade my seat post ring to locking.
A spring loaded saddle will literally give you more traction, as the bike will be able to follow the ground structure if it isn’t rigidly connected to your bones
Could you test out the Promax SP-877 Suspension Seatpost? Seems like the best budget option from a reputable bike parts manufacturer.
You can adjust the height to be pretty much the same. Also, I doubt having the geometry change in such small amounts would do any harm to you long term. How many people have their seat heights adjusted "perfectly" in the first place?
Moreover, instead of transferring potholes and bumps straight into your ass and spine, the suspension should put less strain and shock into your joints. Less jolts and you said it felt more comfortable. You're body will tell you and if you noticed that difference im sure long term it would appreicate it.
Bro, 2 cm is 20 millimeters. If I told you that I adjusted your saddle height 20 millimeters, you'd punch me in the face.
Its a shame most road bikes now have propriety seat posts that aren't round. Only allows this product work for the select few, like the specialized aethos. Bloody bike brands making road bikes parts non interchangeable unless its there brand!
It will be the next revolution in road bike tech that is for certain. Once they stop relying on the pneumatic tyer to do the job you/we will all be faster on the bike that's for sure. It is exactly the same principle as it is for mountain bikes but with high frequency rather than low. road bikes need suspension just like every other vehicle. 15mm would do the job
Setting saddle height would be the same as setting up a full-suspension MTB saddle height. People have been accounting for sag for a while.
Just set the seat height and fore-aft with taking the sag into account (little bit higher than usual and slightly forward). Not sure about the stem though. My guess is that a stem spacer will do a similar thing to set your bar height back to the one recommended during bike fitting. As for the reach, it depends on how do you mount the stem (positive or negative drop), but I'm sure you can also mitigate that by adjusting the position of brake levers / shifters.
great rapport between you, reminiscent of prime clarkson/hammond/may
What ever happened to that heat mouldable saddle?
redshift suspension seatpost works well on my gravel bike, stern is ok but it sometimes move the body downward & slightly rotate your hands when it pivots
i had seen others recommending the Vecnum Freeqence stern,
More Redshift please! The Kitchen Sink bars for example? With all the pads and grips, they look interesting and comfy.
I'm using redshift stem and it really makes a big difference.......
The back of the seatpost suspension seems like an awful skin / finger trap... Besides that, I'd definitely go for a stiffer setup without sag.
What with losing energy? I suppose that front amor is shaking up and down when you what to accelerate and use a bit strength
I have a Cane Creek eeSilk suspension seatpost on my cyclocross bike. It's great! 👍
News flash: Roadies discovers suspensions 30 years after mtbers. 😆
Well realistically touring guys have gotten half that travel out of brooks style saddles for eternity. Plenty ways to skin a cat.
Always had a suspension seat post on my touring bike. New bike, no sus. I miss it and have realised, after hundreds of miles, that's why the comfort has gone. Adds a fair bit of weight but the trade off for touring is worth it.
Ive used the Red Shift stems on road and gravel bikes since they came out. Too many hand surgeries . They made a difference with 2 layers of padded tape.. MAy try a seat one on a gravel bike. Some monster holes in the shade on country road thanks for the videos
Yeah I have four of these seat posts and two of those stems. I honestly don't think I could go back to riding without them. RedShift is that good shit, there Arc Light pedals are another product worth there weight in gold.
I use my arms as shock absorbers by bending them at the elbow and staying relaxed🤷🏻♂️
Did you actually get around to testing the decathlon seat post? I couldn’t work it out from the video. I thought you had but then you a-pear at the end of the video saying they are sold out.
If you could only have one, the stem seems like the smart option. I'm curious to try one.
I've got the red shift seat post on my gravel bike specialized comp E5 and pared with a good seat it's really good. I have no discomfort at all after a ride.
I have big, shiny, chrome, coil springs on the rear of my saddle. Anyone want to take a punt?
Why would people think that this is shite? I had a bike when i was a kid that had springs on the saddle, and it was quite comfortable on not-so-perfect roads and it's simpler than this contraption.
Surely Jimmy can measure the saddle height when Francis is sitting on it and you can adjust accordingly?
It's an interesting idea, however I wouldn't trust the stem, a little change in the hoods angle can easily and unpredictably cause your hands to slip off the hoods, causing a serious accident.
This is very hard to watch. 90% of the time we only see your faces, not the actual product or demonstration.
Hi guys, love your show and all the gags😅
Anyhow down to business.
The trick is on the Redshift or the NCX which I use the latter is you adjust the preload as to make the seatpost virtually rigid.
That way it will only flex when you need it to instead of your back doing the flexing and your reach will stay the same.
On the NCX you can also grind the back of the seatpost away so that it will fit into a D-shape seat tube which was a must for my well used back
The Redshift stem in my opinion should be mandatory for safety
Cheers Scott
Thanks, what an awesome idea.
I have a D-shape seat tube
Suntour sp12 seat post is really comfy. It just removes all road buzz
I’ve been looking into these to relieve back pain from a herniated disk. Have a buddy who got it and it relieves a bit of the shock pressure to his spine.
I have used the Redshift seat post since i sponsored their GoFundMe and have tried them on both road (where it lives) and on hard tail mountain bikes. Still find it a must have.
7:57 '... but 2 cm is still a lot'.
Can you actually hear yourself, dude?
Try a cane creek silk if your bothered about it changing your bike fit position they don't move in the same way and are excellent
