I know the design engineer for these bars and the number of 3D printed prototypes he made is mind boggling. One of his riding buddies is a physician and had the vision. He and the engineer played a large part in making this happen. Ergonomics and comfort were the main design goals. It sounds like they nailed it.
Just an observation: I didn’t see you using the handlebars on the hoods. I believe that is what roadies use 95% of the time. So, is there more comfort with hands on the hoods too?
The fact that this handle bar had mounting options for accessories in addition to the ergonomic design is certainly a game changer.
Not really. I've seen Chinese carbon bars with built-in mounting option. Only thing great about this bar is well considered ergonomics.
I've been using the Coefficient RR on my bike since April 2021 and although I have the luxury of reviewing bikes as part of my job, one of the things that I miss most when riding a test bike is these handlebars.
Great to see that others agree on the benefits offered.
I was particularly hesitant to change at first but it took only one ride to understand the benefits.
Happy to say: this is one of the best product reviews I've done... as the Coefficient RR handlebars remain a favourite.

Thanks Rob, have seen your review and couldn't agree more. Excellent and well thought out product! -N
As someone who studied product and industrial design it's great to see something like this, the ergonomics look really good - darnit Neil now I have to check another piece of gear...
check out the Eyropro - Neil has seen this but has a short memory.
@@zidaz01 Hi Zidaz, yeah I saw this video and had my two bobs worth about them
I've been using these since 2021 and they are just the most comfortable bars ever. I bought a set for my winter bike, as I wanted some more comfort and when I went back to my race back I really missed the comfort of the coefficient bars. Just a point of note, I used a slightly longer stem that normal to give my elbows some room when in the TT position. They are a proper pain to get the brake lines through.
Vibration absorption is really good?
I can still externally route the brake hose and shifter cables right?
@@azizhirkani7043 Yes, you can externally route the cable and hoses.
@@azizhirkani7043 I can't say it's better, but you hands are in a more natural position so the ride does not feel so harsh. Where theses bars are very comfortable is in the drops. There's a small indent for your thumb, and although it's very small, it makes a huge difference.
Coefficient's other bar is pretty good too! I have an unconventional bend in my right wrist due to injury so it didn't work for me but my left side it fit really well! It has the swept back & angled tops (the natural elbow tuck is real!) and a thumb notch in the drops that made for a solid grip & a bit of cushion if you were at the ends!
Coefficent copied the Eyropro which I own and have patents for - they just dont care about copying my design and selling the credit for the design.
@zidaz01 bother defending your patent or are you just gonna make fruitless claims?
OMG! It's my handlebar! I did a bike fit with Colby 2 or so years ago. This bar caught my attention and it wasn't too long until I had one installed on my bike. I definitely rate it.
Chris Froome's elbows have entered the chat!
Yess, rep Oregon! Stoked to hear that! My parents opened wind rider bikes just outside ptown in the 80’s as one if not the first mountain bike stores in Oregon/PNW. I grew up here and always loved seen the influence they made on the early biking community to inspire what it is now. Great video too, I never saw your content but I’ll have to subscribe. And maybe get these bars for my dad. He rides everyday instead of drives and is 72 now so I got him a used ebike to help with the all the hills around here. Bike is life💛
Ritchey also have a set of bars called 'evocurve', same back sweep in the tops. They aren't as fancy though as they are relatievly standard, good reach and not too deep drop. Also a bar to consider if this is too expensive and grotesque for ones liking 😅
actually the Coefficient bar is an up/down sweep as well so you can ride all day pain-FREE. :-)
The older Madone SLR (2020 model I think) has a slight backsweep on the bars, and I absolute love them. I’m tempted to try these on my Aethos
Damnit Neill, now I have to buy before they sell out! You are the DC rainmaker of bikefit advice afterall
some sizes are already sold out, fyi 😞
Handlebar ergonomics are still stuck in the 1980’s. These are a massive shift in the right direction,the backward sweep make sense. Pity most integrated cockpits sold on the current crop of bikes are rubbish.
I'd hate this sweep
@@veganpotterthevegan
The wrist resting in a state of slight ulnar deviation with the forward sweep is more anatomically appropriate but clearly not for all.
@@veganpotterthevegan Try it first! 😉
@@veganpotterthevegan different people different preferences I guess ☺️
Have you even looked at or used a modern handlebar beifr something so silly..
Have this handlebar on my new bike and have ridden ca. 400km with it...I am loving it!
My only pushback Neil and love your channel is...I believe the FSA Kwing is a better handlebar ergonomically. It incorporates many of the features the handlebar you review however with one MAJOR difference.
Where the shifter hoods intersect to the top crest of the handlebar on the Kwing, this bar surface is 'flat' and not a conventionally shaped round tube like yours shown and traditional handlebars. What FSA engineers figured out is...where the shifter hood intersects with the top of the handlebar...this land or perch the heel of the hand rests upon....having a flat surface off the back of the hood built into the handlebar...call it a ramp off the rear of the hood surface...a flat land is more comfortable to the heel of the hand versus a tubing radius which more point loads the heel of the hand. PSI's/force/deflection of the heel pad of the hand. The FSA Kwing is a brilliant handlebar, the best I have ever ridden.
Love your insight and wanted to share mine.
Cheers from America.
I have sampled the K Wing in the gravel version. It is quite well done.
Bars look great. Ergo adjustments make so much sense. Not sure about the $399 price tag….perhaps I’ll look for an alloy alternative…or an Ali alternative.😂
$400 is steep AF. They'll probably be the solution to my issues but too much to take a gamble. I wonder if there is an option to rent/loan/try these before buying.
@@larisonjohnson
Can you give a int about the link or product name?
I know links in youtube comments are automatically deleted in most cases.
Thank you.
@@christianholmstedt8770 Found them from Tookrock and Toseek. Of course now Ali puts them at the top of any search I do, so it’s hard to tell what words trigger them. I think the Toorock solution was called broken wind. Happy hunting!
@@larisonjohnson
I think I found it. Looks similar to the other version sold by the company making the one in the video.
Same idea and similar angles but njust not as 'aero' in design.
Found under the name Tookrock.
Thank you!
@@larisonjohnson actually the up/down curvature which makes the Coefficient bar unique is not incorporated in those ali bars. The coefficient bars are also made at the Factor factory so you're also paying for quality and reliability - which helps when descending like a MoFo down the mountain. :-)
Syntace Stratos 200 base bars had a very similar backsweep/downsweep design. They were a favourite in the local bike messenger scene back in the days.
Never thought they were good for messengers, having your wrists in that angled position (top bars) was not great for reacting imo. But they looked alright 😂
FINALLY! I've been saying "sweep back" handlebars for years! Its so obvious I really don't understand why it hasn't been done since year dot!
I ride 17 deg sweep on my MTB and it's a game changer.
I reckon this bloke actually knows what he’s on about, refreshing.
These look amazing. The only downside I see is the lack of aerobar attachment points. I love my aerobars, but not for the speed gains. I love them for the extra hand positions available for those metric and imperial century rides. It's more than just the hands that get uncomfortable, and being able to stretch out on the aeros and "relax" is something I've grown to love.
same here... nothing alse than round bars will come on my bike since riding 200-300k / day will just kill your wrists imho
But there's a round section on the bars no?
I’d be curious to see what your thoughts are on the Lamda Cross Wing handlebars. Those both look like very comfortable bars.
they way they sweep before dropping reminds me of the Nitto ADB-X track bars from the early 80s ngl
Hope to see slight angle sweeps in future handlebars! Many riders just blindly use whatever uncomfortable blocks of alloy/carbon are mounted.
Ritchey has been doing a similar concept to this for a couple of years with their top carbon standard bar. I don't know if it is used in the aero model though. I'd have to look that up.
I have this bars on my bike for about 1/2 year now. Very good overall. However you really need your time to set these up. I use them with a Force AXS groupset with everything routed internally. The hole in the middle in very small (you can see it in the video). While its not designed on purpose to route the braking cables through it- it works.
Can you run the break cables under the bars like a traditional bar?
@@MrMars121 I think you could do that. But there is no groove or something like that on the lower side of the bar so one would feel the hoses for sure. If you don't want to go via the small hole at the back I would use the cable guides (you can see those in the video).
I ride these on my Orbea 38vm Comfy on the tops and all day riding. Stable in the drops too
have been testing turning my hoods inward to get a better wrist angle when in the hoods, now I can get a better angle on the tops too.....
Awesome video! I have been looking to change the handlebars on my Aspero and these bars jumped to the top of my list! I ordered them over the weekend and cannot wait for then to arrive!
I’ve got an aspero too. If u don’t mind, can u update, this may also help with my right wrist ECU tendon injury
Looks very cool and comfortable. My main issue with these all the way flat top bars is there's no room to fit an aerobar. And since I cannot afford a TT bike, I will need a handlebar with that option.
Been saying that for years. Also on MTB's. Would like to see if they will rethink them as well, especially the last part where the grip is, if that is swept back a tange then it will be way more comfortable.
I love this bar. So many hand positions. Been using it for over a year now.
Well then...
I had a similar idea during my last long multi day ride for bars with a backsweep in the flats.
Nice to see someone actually had the idea first and did it even more thought through :D
I don't like any radical designs in bike industry but I think this handlebar actually looks good. They could just make this computer mount lower in my opinion. Thanks for this video. I might get one of these some day.
The computer mount is where it is largely for structural bracing on the web behind the computer to tie the two halves of the top together in a way that carbon fiber likes (a straight line). The mount can only drop so far before the computer hits that structural element… so that is where it ended up.
Be good if they also had a bit more support for the fore arms while on the hoods, like Remco. (A bike fitters review of those bars would be fantastic)
I sent them this line for their advertising. "We put the handlebars where you put your hands."
hahahah OMG
What a great find - nicely explained. Thanks.
Finally Neill Stanbury is complete. He rests his butt on a Selle SMP, which he kinda admits IS ugly. Now he rests his hands on a pair of Coefficient AR/RR, which he admits is a little space-ship looking. Thankfully, he endures the grotesque. Because now numbness in the butt and numbness in the hands are gone, for good. Neil is now in full-end-of-range comfort. We feel you Neil! We do!
Laugh in background is the best
The biggest advantage to "aero" drop bars is: we are finally getting some flat surface to rest our numb hands on. Round handle bars for cyclist are a pain in the.....well hands. We veteran cyclists have had to live with the most stupid bikes for half a century, and they are only getting more stupid. But once in while, we get something that is actually an improvement. Now given these handlebars are flat because of aero-dynamics, I doubt comfort was a thought in their little brains because the rest of the bars are round. I don't ride road bikes on the road anymore because after 50 years of stupidity, I don't want to. Now I convert a mountain bike for the road, use bar ends that are square giving me a flat surface, and aerobars so my hands are completely unstressed. The mountain bike comes with excellent road gearing for my mountainous country with 24-34-44 crankset, I add a 12-13-14-15-16-17-19-23 cassette for close ratio high intensity training but still have gears low enough for climbing in the steep high mountains of my Northern California wilderness. Then I add the strongest 26x2 tire in the world and strong wheels and I am off on the strongest road bike in the world.
I would disagree with Neil on the inward angle of the tops, which a lot of bars have although not to this extent. Having tried bars with an outward sweep (like Vision/FSA and SQLab) the wrist position feels way more natural, similar to having the shifters pointing inwards. The slight outward positioning of the elbows also feels like it opens up the chest a lot more, making it easier to breathe on climbs. All based on my personal experience of course...
Agree 100%
The tops are a narrower grip than your shoulders so your lower arm and hand naturally fit to a forward top sweep.
An mtb is the opposite - the wider than shoulder bars make a backsweep more natural to grip.
Your idle wrist angle changes with your elbow bend. People with poor fits and locked out elbows will want the opposite of people who ride in the Sphinx position with bent elbows.
@yoog nothing to do with locked out elbows or not. All to do with angle from shoulders to bar.
@@alexrandall9966 Hold your arms out straight with your palms facing down and your palms facing up. Which way feels more relaxed? Now bend your elbows and bring your hands to your shoulders, palms out and palms in. Which way feels more relaxed? With your arms outstretched, palms down will feel more relaxed. With your arms completely folded, your palms facing toward your chest will feel more relaxed. With your elbows bent 90 degrees, your forearms will also want to rotate 90 degrees.
If I grip a piece of tube and look at the angle between it and my arm it is obvious that the natural angle is more than 90°. So a backsweep makes sense to me. Even more so with the downsweep. A bend down and forward would be really awkward.
I tried some bars (FSA) with forward bend and that is definitely not compatible with my wrist.
I have the AR bar and it's the best feeling bar I have ever ridden
Probably the only thing I don't particularly like is the computer mount, putting the computer above instead of in-line with front of the bars, otherwise look cool.
I ride them on my steel frame. It looks wrong, but is soooo comfortable. Best hand positions ever, won’t go back after 2000 miles.
I have just ordered some on your say so Neil,they look aero and very comfy so i will let you know how i get on....expensive but hopefully cost effective!
You should really come see the industry here (Seattle/Portland). We’ve got all kinds of fun bits. Fixies, road, velo, mountain and gravel racing. My friends and I are still willing to find the limits of your elves build(s).
Hi Neil. Have you seen the pro plt ergo carbon? it has a similar concept but in a more conventional design. it is the most comfortable handlebar for me. greetings.
Get them Cam. We need these test NOW
My question is: what changes in bike fit when you switch to this bar. If I have a spot on fit on my bike right now, how would I have to change things to make it feel as good (and then better with the new bar)? i.e. stem length, stack, etc.
It is designed to be a drop in replacement. The contact points are very standard, so as long as the reach and drop off your current bar is similar to the coefficient bar, it puts your hoods in the same spot and then you just get the ergo benefits on the tops (and everywhere else, too!)
I like everything about this bar with the exception back sweep of the tops. To me this makes no sense. Ones shoulders would have to have a width of 2 inches apart for the extended arms to grip the tops without forcing the wrists to bend. If anyone has a normal width between their arms, when reaching for the tops, their arms will be angling in towards the stem. That means your wrist is going to have to make a severe turn to grab the tops of these bars. I am severely short-waisted so, I ride the tops most commonly. The good news about the Coefficient bars are the drops would be closer to me when using them but then again that can be easily solved by stem length. SQ labs 312R handlebar is mentioned in other comments I have read below, and I looked at them, and that design at least to me would much better suit my needs and does look a lot more ergonomic for anyone spending time on the tops. Overall the SQ Labs bar seems to make a hell of a lot more sense.
How are those bars for small hands (reach to shifters, ...) ?
The reach for shifters seems to be very long in the drops.
When you switched to this bar, was their any compensation needed for the stem length to get your position back to where it needed to be?
None needed. Stem mount is inline with the bend to the hoods. Reach is on the short side. Good IMO. You can also mount a GoPro underneath below the head unit mount. They offer varying mounts. After the initial nightmare of cable and hose routing I am very happy with these bars. Would like to put the other version on my CX bike.
just get the same size bar you're used to and keep the stem length as is.
I don't even have a bike anymore but looking at the design alone makes me want to get one once I bought a new roadbike.
Damn it, I was trying to buy another one used but now everyone's going to know about em. I actually lost an auction for one of these a few months ago and wound up trying out the next best thing I could find... the Pro PLT ergo carbon bar. Seriously the most comfortable bar I've used. Still waiting to try an RR though.
How would you size the stem compared to "normal" handlebars? Looks like a shorter stem is needed.
I thought exactly the same. Any take on this?
Just order your same size bar (Coefficient bars are measured standard c-to-c at the hoods, and keep your same stem length. Easy peasy!
@@philippwiehl9689 Just order your same size bar (Coefficient bars are measured standard c-to-c at the hoods, and keep your same stem length. Easy peasy!
I've had these bars for my gravel bike for over 6 months, and it changes the ride so much better on and off road, especially when you ride over 100 miles on gravel.
Quick observation: If there is a rise at the corners, where the flat section meets the section pointing towards the hoods, then that would be a recipe for discomfort in the palms over long rides.
Had a handlebar that had a rise and had to get rid of it. Good for short rides, but very uncomfortable over longer rides!
actually the bar works best for those who want to extend their rides - meaning comfort over the long haul. There is no rise where you are mentioning btw. I ride mine exactly on that spot and can go all day pain-free finally. yay
I've always noticed how a bit of backsweep completely eliminates the elbow poke, I try to add some myself by bringing the thumb over the top, ahead of the bars, but you would need a lot of trust in you bar tape to do that in the peloton 🤣
how is it possible you forgot about the Eyropro handlebar I sent you and you actually recommended it to your clients?
Fu. . in oath!
Well funny that SQ Lab does exactly the opposite with their 312R dropbars. They put frontsweep to the top of the bars to bring the wrist in a straight postion.
This handlebar is AMAZING! DAMN I need one..
This is great, would be nice if they made a model that mounts to steerer tube. Also, can someone overhaul mtb handle bar ergonomics?
Try the Slasa Bend (Bend II) with a 17 deg sweep. It's a game changer for me.
Coefficient is on it! Stay tuned...
It'd nice to see something purely designed with rider ergonomics in mind !
I have a question, moving from an regular alloy bar .. to this ... Same stem ... Would the reach be different? Also will it improve comfort in vibration since it's carbon? How good are these bars for vibration absorption?
I love my Ritchey Butano (latest version, V2). Flat top with a little bit of back sweep. Cheap too.
Brilliant idea
I've been riding this bar for almost two years now. It's the most comfortable bar I've ever used. Only complaint is some bar tape is too short to wrap all the way up (I don't like the feel of unwrapped carbon).
just get the custom grips to put on the tops and never have to worry about short tape again - or buy the Coefficient bar tape! 🙂
Paraic Mcglynn of Cyclologic helped design these
Looks like it could be improved by making the bar for mounting onto the bike narrower, that would make even more room for the knees.
Just don’t understand why they make the internal cable routing so difficult. The cable doesn’t have to be inside the bar when bar tape is on top of it. Just a cutout on the bottom part of the handlebar will do
It’s why I hate these bars
Am I correct in assuming that the design does not an effect on reach?
It seems really good! I hope one day they might create a handlebar like that but that also accept a TT bar mounted on it, for endurance rides!
They should really make an alloy version because I drop my bike sometimes and I'm too poor for new carbon bars every year.
Great review. I too have an all mechanical groupset. Was wondering if you had to install longer cables, as suggested in their instructions? I might just tape my existing cables to the bars underside to avoid tight corners.
Brilliant Design!
Too bad it's incredibly expensive for someone to buy to try. These would sell more if they made an alloy version if that's possible
Top shelf gloves are a must 👌
2 minutes in and I am sold…
Would love to see how to fit this bar vs a standard bar? Or what adjustments would I need to make when I swap this bar in vs a standard bar.
you just order the same size you currently ride since the Coefficient is measured C-C at the hoods. And with 31.8 clamp diameter. :-)
Think of the watts Froome could've saved!
hahaha since he wouldn't have to do that head bop thing to breathe easier! hahah
i like traditional old school round bars.
Too steep for my budget, but I love the thought and engineering behind the design of these bars.
Seems it helps to reduce shoulders internal rotation also.
Looks good!
Looks awesome
I was hooked until I checked out the website and the price! Need to be about 1/2 the cost before I’d be interested.
I love it! And love your channel mate!
I have bull horn bars because that's the real comfort position.
Ok, just ordered one from Pushys. See how they go!!
How after a year? Still do good opinion? I am in the place where I starrted to looking for a bar to my new project 😄
£400 quid, just wear good gloves and use cinelli handlebars
looks pretty smartly designed but i wish it had 36cm and flared options
not yet but there are talks of creating a 36. It's a new company so still growing.
There is a small flare. 2 cm difference between hoods and drops.
@@carlosflanders518 10° is pretty negligible. i think thats pretty standard on pretty much all road bars, you don't really notice it. 15+ feels flared
@@Carftymk ! really like 12 deg flare: 38 at hoods and 42 at drops. Helps the wrists and good control for cornering.
@@carlosflanders518 what bars do you have? it's hard to say without trying exactly but i think my ideal would be 37 hoods 44 drops
I've been looking for road bars with back sweep for ages! Being an MTBer its really awkward not having back sweep.
What bike is that? Looks amazing
Fixed Garmin mount means you can't rotate it to better angle to visibility. A small change in angle can change reflections enough to have a big impact on how easy it is to read
Yeah Garmin should follow the example of Wahoo. The effect you describe is way less there...
Coefficient is working on an adaptor for angle adjustment, fyi
@@christine9842 so easy to do in the middle of a ride? (Most mounts seem to be adjusted to a fixed position) feels like the easy solution is have a round section of tube there.
Would still need to figure out how to mount a light (light and motion seca so orientation matters) though looks like there would be enough room for the redshift utility mount for the shock stop stem to hold the Garmin and use the mount on the handlebar for the light
It is surprising Neill considers this handlebar as "best". It can be aero, sure, the downward bents are good, but the shape is actually anti-anatomical. Take a look for example at Ritchey Kyote handlebar, the idea is that within shoulder width the handlebar would go outwards, at shoulder width there is turn, and only then the handlebar goes inwards. If you get this handler (as in the video) the strain is on the wrists and you can easily check it by getting you chest next to handlebar.
you really need to put your hands on one to see its next-level comfort benefits! It helps people to extend their rides pain-free!
If the bar has modular option for adding bike light or camera mount under the headunit mount, this would be a perfect allrounder ergonomic handlebar I've come across.
It has both of it, check the website
Flat bars manufacturers should take notes
Very nice. 👍😎
PRO PLT ergo carbon has a similar design (less pronounced though)
Sure I get the pronation help, but what about the addition of ulnar deviation?
Thoughts?
