#AskGMBNTech I have a height adjustable Fox Talas 32 on my bergamont Threesome, but it's stuck at 120mm and doesn't want to come out to its full travel. I always put some oil(I don't know how to call it in english) on it, but it doesn't help. Whats the Problem?
#AskGMBNTech hi Doddy, First off love the show!! Basically my bible for all things tech and maintenance... I'm waiting on a new transition scout frame to arrive and have a question / request for your opinion on trail, offset and stem length. I've got a medium on order and the new carbon scout utilises a 40mm stem with a 37mm offset. Now, given that I'm ordering a frame set not a whole bike and currently have a 50mm stem paired with a fox 36 fork which has a 44m offset. Don't particularly want to try and a) buy and find a new fork in stock and b) buy another stem, yet I totally respect the engineers that designed the bike... Thoughts on how much of a difference a 44 not 37mm offset would make and 50mm not a 40mm stem would make when looking at the scout? Cheers for the help and stay safe!
@AskGMBNTech hi doddy I'm really confused as to why some bikes have a jockey wheel above the cranks. Bikes such as the aurum hsp c2, why do they have that jockey wheel surely it adds weight to no obvious benefit. Could you please enlighten me on this please. Thank you.
@@ffturbo Finished the bike a month ago, I broke a seatpost (and the saddle because of it) and a crank bolt, but the bolt was an installation error done by me 😒👍🏻
Favourite vehicle? That new Taycan is pretty slick, electric and all. As for Group B rally I'd have to go with the Lancia Delta S4. And that Singer 911 Safari sure is VERY drool worthy!
VW R32's are absolutely awesome! But that is my bias coming from owning a 1.8t. Any touring wagon or hot hatchback to be honest. And you guys definitely get all the good ones across the pond.
Favorite vehicle. My Truck. Hauling yard rubbish, getting Firewood, bikes over the tailgate, pulling a camper, loads of kids things, getting through deep snow. It’s literally Saved me and enabled me more times than I can think.
Stuff I went with so far: Wheels: Nukeproof Horizon V2 ~450€ for front and rear, or any branded super budget if you don't care about engagement (this is worth spending a bit more on though). Bars: Brand-X Riser or Flat bars ~15€ - 18€ not the widest but the price is a steal. Dropper: Brand-X ~190€ at least for the larger ones. Drivetrain: Microshift Advent-X Cassette, Derraileur & Shifter + Shimano M5100-1 1x10 + Shimano Deore XT MT800 ~230€ and lighter than Shimano XT
My new forks (Lyrik) make a loudish slightly troubling whoosh sound when moving, worse with faster rebound. What noises should we worry about and what's normal? #AskGMBNTech
Doddy... would greatly appreciate an in depth vid on "How to choose new wheels for you bike build". Things to consider, avoid, tips and much more :) Cheers
Favourite vehicle: I’m only 14 but my dream car is a Ford ranger so I can take my friends to the bike park since there’s non with one riding distance in our area
I was going to suggest a dirty/clean drivetrain test as well. ## I deep-cleaned the chain on my single speed commuter the other day, and next morning it felt like I had easier gear. 140 + - links with a little bit of resistance each makes a big difference, especially if your chain is getting rusty, imo .. Possible method: bike with a power meter, ride a lap at constant (controlled) speed with a chain from some unattended bike, then clean and lube the chain and repeat at the same speed. Measure the power difference. + Unattended is a relative term. Look at the bikes that park in front of Tesco's... ;-!
Regarding the high pitch noise from the wheel. I have the exact same issue on TWO different DT wheels (xm1650 & xm1501), both brand new. Both wheels are in the shop waiting to hear on a solution. I have a thread over on the MTBR forum in the wheels section.
Favourite vehicle: the lancia stratos. It was the only car ever built purely for rally. Any transformers G1 fans will know wheel jack. He transformed to the stratos. Definitely search UA-cam for videos. It was a beast of a car.
A small word about transmission - chain Chain can be one of cheapest of the product line. For example Sram 10 series: 1030, 1050, 1079, 1090. Tested every one since 2012 (when my 10spd bike arrived). They working exactly same at 10spd transmission, same shifting performance. Difference is weight and rust protection. But not worth spending extra money for me. And lightest "90" series can be damaged easier than "50" or "30"... This happen to me ;) But my favorite "value for money" is basic X series KMC chain. Maybe a bit heavy, without rust protection, but never fail. And shifting performance is outstanding at Sunrace casette.
If my memory is correct, there was a time (1990s?) that stock trials bikes in competition were required to have seats and derailleurs. It was an effort to keep them looking like a mountain bike.
@@andym436 back in the day there were ‘stock’ bikes which has 26” wheels and looked like a normal bike and there were ‘mod’ bikes which were 20” and seatless
Hi doddy, I might have an answer for Marek. I’ve seen some skeaking on disc brakes because the brake calipers aren’t fitted correctly because of the paint on the frame. This can be easily corrected with the park tool disc brake mount facing set DT-5.2. It’s worth a shot!
just a suggestion on a video you were saying for the winter, how about just a normal week, 2 identical bikes, brand new, you ride both 1 hour per day, so you will be riding 2 hours a day, same route, same day, alternate what you will be riding first, the other one will have no cleaning, no lubing at all, straight from the buying it, and the other will be treated like a queen.
Steeper seat tube keeps the seat farther forward allowing it to be more out of the way for the rider to get low and back. And really the seat is only used for strolling around the top of the course, or resting at the bottom, or to lean on during the push back up.
Hi Doddy, love the show As for the vehicle, if I can't go for a mtb, I'd go for a BMX. But if I had to go for a car, I really like subaru rally cars. Cheers!
I bought the Microshift Advent x 10 speed drivetrain. Loved it for the first five months or so, great trigger feel and sound gear changing, but the derailleur broke. The clutch stopped keeping the chain tensioned enough, so chain dropped continually. It was easy to see that the chain had become too slack on the drivetrain. Took derailleur to four mechanics, all said can't repair it and one even said don't buy another one. Tried to claim under warranty, so sent Microshift a comprehensive video of the issue and was told it looks normal. Took it all off and bought Shimano XT. I will be sending the derailleur back to them so they can see how badly it malfunctioned. Not the best experience.
To the guy who has a squeak in his DT Swiss wheels, take the freehub off and there is 2 bearings inside with a spacer between them, the noise will more than likely be coming from there. I had this issue with a brand new bike with similar dt Swiss wheels.
Very hard question. For me to use everyday and easy on maintenance, I'd probably have a BMW E30, But for Group B Rally cars, My favorite is the Peugeot 205 T16. For my fantasy car, it's a McLaren F1.
For the DH bike seat angle, I believe the seat angle is really slack to the seat in a position where the seat can be gripped between the knees on extreme descents. I can't say I've ever done it but I believe that's the logic.
SRAM NX 11-speed system cannot be beat for the price. Very smooth shifting. Since I don’t need a 52t dinner plate for my lowest gear (I raced open/pro singlespeed XC for five seasons) then the 42t fits the bill perfectly for me.
I've done the "no maintenence test" this winter. Every day, snow and rain, ridden hard and put away wet, never even washed it before last weekend. Result: worn out chain and casette. thats it really. chain could be twisted past 90 degrees over the chainstay, and it did no longer shift properly. new cassette and chain on there and cleaned and lubed up the rest and the bike's as new again... I now question if its even worth the time it takes to wash and lube it every two weeks, I mean they're cheap drivetrain parts.. Then again its nice to have a nice and clean bike to ride..
In relation to the high pitched squeak in the drivetrain, my friend had a similar problem which turned out to be a hair stuck between two parts of the hub which made a high pitched squeal when the wheel spun.
Never too old for lego Doddy, 46 and I still have to have some every Christmas, got the Quattro last year!😁👍 As for fav car, I'm just looking forward to chucking the bike in the back of my mk1 escort van when I finish restoring it.🤣
Fave all time car.... Porche 928, first seen coming round a corner in Abingdon back in 1978!!! That image lodged in my mind to this day! (But never owned one)
Favourite vehicle? 2020 Mercedes f1. The efficiency, performance. Engineering masterpiece. If we're thinking usability though, gotta be the Porsche 911
I spot the sport quattro, and the question is read 😂 insane car, that sound! And saw the offroad Porsche. What a beautiful brute! About the budget stuff, ergotech has nice rugged handlebars with safety indication. And cheap. Tyres i found a lot of people sell good sets second hand. (At least here in holland) Upgrade brakes? Try bigger rotors. Adds a bit of weight but great results in performance and modulation. Cheap chainrings, pretty nice stuff on Ali. Manitou usually got nice budget forks.
Side Note - (@ 19:00 mins.)Turns out the SRAM B-Gap adjust template tool is slightly different for the AXS mechs... not sure why. Its purple rather than red. It might be a case of SRAM selling the same thing twice in two colours, or there could be some differences... I'll dig mine out to check, but worth being aware of.
Even on forks, while obviously not as good, some budget options are pretty decent for plenty of people. The rockshox recon forks are a pretty good value, if you're doing basic riding
Marek that high pitched sound you describe is normal on DT swiss 36 ratchet I think its the internal springs which are making slight resonance, happens to my wheels and I've heard the same sound on some youtube videos!
My 2nd comment which is rare if ever, Nice 1 Doddy that was a good episode with some proper q&a's m8, Quick note on kelvin, i have worked on my own bikes for about 40 years, from wheel building to welding bits of frame & even to this day i have referred to kelvin on a few things, even though i have probably come across even the most bizzar of problems there is still always something to surprise myself with. Kelvin does things the correct way which is always useful to know, he is like the Haynes car manual for bikes, or should i say the bible of bikes.
Cheaper group set is the way to go. I run 105 on my daily commute gravel bike and slx on my single speed and the original cranks on my downcountry still yet to wear them out
As far as automotive vehicles, when I was in the Army I had a 1984 VW GTI, but I saw a 1988(?) VW GTI Wolfsburg Edition in Germany that I just drooled over.
If your hub (or seatpost) is the correct diameter or width, then no. There should be less than a millimetre of movement in the frame between the fully open and fully closed positions of the QR, when the hub or post is in. If, however, you are trying to get a narrower hub between the dropouts, and are clamping the frame around that narrower axle, it will force the frame stays together and put tension on the weld around the BB yoke. This may eventually cause a stress riser and cracked chainstay, but won't cause the frame to be permanently bent, as the distance a QR will travel when closing, even with a narrower than required hub, won't be enough to reach the point of plastic deformation of the frame, and it will spring back to it's original shape. If you clamp a QR seatpost clamp around a smaller diameter seatpost than is supposed to be fitted, it can ovalise your seat tube at the clamping point, and prevent you from ever getting the right size one in. It won't cause a broken frame, but will be annoying. You can crush hubs even if they are the right size if you are a complete beast, but I've not heard of it happening. The real issue with an over -tightened QR is that it's virtually impossible to get them undone again.
#AskGMBNTech Hi Doddy, two part question.. I have a 2005 Trek Session that I want to slacken out a bit. It still runs the original Manitou Travis 180mm with a 1.5 inch tube all over. Is there an angled headset for this? Next option would be to get a new fork with a tapered tube and a 27.5 inch wheel, is there an angled headset for this concoction as well? I just want to slacken the bike, and not necessarily raise the front too much.
For tires, CST (a chinese tire brand) owns Maxxis. I won't be surprised if they are made in the same factory. If you want affordable performance, go CST.
My Rockshox reverb dropper has failed (blown seal) 3 times. I know they make a lot of them, but not a great ratio for me. Brand X Ascend worked flawlessly since day 1 on my other bike.
#askgmbntech. I've been looking at a 1993 Marin Pine FRS, and wanted to get your thoughts on fitting modern-ish air fork internals to the original Manitou carcasses, if you will. That way I keep the small axle to crown dimensions, wicked retro looks, and rear fork (shock) compatibility, but get a more progressive and sensitive ride. thanks!
I think air spring will get complicated because the Manitou is an elastomer fork and was never designed to be airtight. I‘d go for coil springs. Doddy had that on an old Rock Shox and it seemed to work good. I don‘t know if there is a hydraulic damper for a Manitou 1 but with such little travel you might get away without one.
@@chrisridesbicycles I was thinking it may be possible to insert an airtight sleeve containing the internals into the fork lowers to keep it airtight, and mucking around with modern seals. It wouldn't normally be an issue for me, who loves OE specced bikes but I want an FRS to actually ride, not just to drool over.
@@judechandler5102 I guess you will have to build much of it from scratch since modern forks have bigger diameters and the internals will not fit into the old Manitou. Good luck though. Send it in if you are successfull. I‘d love to see an old silver-and-anodized Marin in working condition.
It's worth buying good bars & stem for i have snapped many, my worst one was when I got off the train in North Wales for a week of mountain biking, got of train cycled across Barmouth bridge on route to mom & dads place and bang bars snapped, this was about 30 years ago and do you think I could find a replacement.......no spent hole frellin week cycling on the roads with a tree branch as a set of bars which to be fair were bloody great, just didn't trust them on my rock hopper comp as there was a lot of flex due to using willow as would of snapped if anything eles
#AskGMBNTech I bought a new KMC 9s chain because the existing one I'm using is worn out per the chain wear tool. My problem is, the chain skips when pedalling. What bugs me is when the old chain is put back, it doesn't skip. Thanks a million!
Sounds like your cassette is worn aswell. Check the teeth of the cassette, if there not uniform, often looking like a sharks fin, its too worn and should be replaced as well. If the cassette is worn by the same amount as your chain it will skip less, but you should replace both as not doing so will wear your chainring prematurely.
Favourite vehicle? A classic Mini. I have one, plus the Lego model, plus the same Audi as you. Oh and I've had a passenger ride in an ex-works S2 on a rally stage. They are indeed completely bonkers!
i got hi pitch squeal from sealed bearing, i checked the bearing inside and i found the grease getting wet, replacing grease or just add more grease on it kill the squeal
I’m on your wavelength Doddy: Favourite: 1986 Land Rover County V8 (110), parked in my mum’s carport. Dream: Yeah, something all wheel drive, turbo and 5cyl.
Car wise it would have to be either a 1970 Dodge Challenger RT in White (and then people could call me Kowalski) or possibly a Hudson Hornet. But just recently I've learned about the Icon A5 Sport Plane and think I really need one of these (learning to fly might be a bit of a cost).
#AskGMBNTech hi I'm looking to get a chain guide as I keep dropping chains. I have a jamis Dakar a2 and the chainring is a suntour SR and you can only just see there used to be a wider tooth every 4 teeth.i can't find any more in stock and wouldn't know how to replace it anyway. Can you make a video on how to Identify the chain guide mounting holes and which guide I should buy. Thanks
So for your vehicle question i would choose a BA - 350 wich is a heavely modified Ford F-350 with lots of Suspensiontravel, fat Tires and tunend Diesel Engine. It is big, wide and even halfway practical for lugging Stuff around. If you want to know more about it ask UA-cam for a Video
Great, informative vid as always. Easy vehicle choice for me. Lowered VW Transporter Sport line. Kitted out for bike and living in. Wales, Fort William, Les Gets.... Oh shit I've just woken up... Oh well😢 keep safe all
#AskGMBNTech Hi Doddy. I will soon be upgrading to my first dual sus mtb. Watching your video's, you have mentioned using WD-40 to drive out moisture from pivots. Looking online, I see many people say that WD-40 in pivots is horrible for the bearings. Could you please school us on when and how to remove moisture safely? Love your work!
I love shimano and I’ve got a shimano slx 11 speed 11-46 cassette. The cog before the 46 tooth is 37 tooth. Too big a jump imho. The sunrace equivalent has a 40 - 46 jump. Much more usable. In my case I’d prefer the sunrace to the shimano.

It might be a case of SRAM selling the same thing twice in two colours, or there could be some differences... I'll dig mine out to check, but worth being aware of.
Even on forks, while obviously not as good, some budget options are pretty decent for plenty of people. The rockshox recon forks are a pretty good value, if you're doing basic riding
Marek that high pitched sound you describe is normal on DT swiss 36 ratchet I think its the internal springs which are making slight resonance, happens to my wheels and I've heard the same sound on some youtube videos!
My 2nd comment which is rare if ever,
Nice 1 Doddy that was a good episode with some proper q&a's m8,
Quick note on kelvin, i have worked on my own bikes for about 40 years, from wheel building to welding bits of frame & even to this day i have referred to kelvin on a few things, even though i have probably come across even the most bizzar of problems there is still always something to surprise myself with. Kelvin does things the correct way which is always useful to know, he is like the Haynes car manual for bikes, or should i say the bible of bikes.
Cheaper group set is the way to go. I run 105 on my daily commute gravel bike and slx on my single speed and the original cranks on my downcountry still yet to wear them out
I currently own an M4 which I am absolutely in love with.
Great show, doddy✌. I think The dirty/maintained drivetrain vid will be interesting, especially seeing the end result showing the damage
Fave car is a 1980's Citroen 2CV two-tone. I adore them as they're soo cute!
As far as automotive vehicles, when I was in the Army I had a 1984 VW GTI, but I saw a 1988(?) VW GTI Wolfsburg Edition in Germany that I just drooled over.
SUPER LUBE GREASE IS AMAZING !!!!!!!!!!!!
2 Choices - Spray on or THICK Grease : Both Clear and Synthetic
The Brand-X Ascend externally routed dropper posts are great. Yes, heavy, but I’ve never had any problems. Giant Contact dropper has been a hassle.
1984 VOLVO 242 DL.
Not turning any heads but solid and sturdy.
Should deffo do a factory tour of superstar components in lincoln
#ASKGMBNTECH is it possible to bend/ weaken a frame by over tightening a quick release?
If your hub (or seatpost) is the correct diameter or width, then no.
There should be less than a millimetre of movement in the frame between the fully open and fully closed positions of the QR, when the hub or post is in. If, however, you are trying to get a narrower hub between the dropouts, and are clamping the frame around that narrower axle, it will force the frame stays together and put tension on the weld around the BB yoke. This may eventually cause a stress riser and cracked chainstay, but won't cause the frame to be permanently bent, as the distance a QR will travel when closing, even with a narrower than required hub, won't be enough to reach the point of plastic deformation of the frame, and it will spring back to it's original shape.
If you clamp a QR seatpost clamp around a smaller diameter seatpost than is supposed to be fitted, it can ovalise your seat tube at the clamping point, and prevent you from ever getting the right size one in. It won't cause a broken frame, but will be annoying. You can crush hubs even if they are the right size if you are a complete beast, but I've not heard of it happening. The real issue with an over -tightened QR is that it's virtually impossible to get them undone again.
@@judechandler5102 And then you need to use a tyre lever or something to get them undone! 😭
@@gmbntech and then the rubber mallet you need goes missing so your only option is to use a hammer and you end up striking the frame😥
@@tonymcnally9355 damn. You went down one long road of bad luck. sorry about that m8
Norton domiracer always been a bucket list bike for me.
Favourite vehicle Gtr r34
Should defo do that for next winter and see the difference and compare your drivetrain afterwards
#AskGMBNTech Hi Doddy, two part question.. I have a 2005 Trek Session that I want to slacken out a bit. It still runs the original Manitou Travis 180mm with a 1.5 inch tube all over. Is there an angled headset for this? Next option would be to get a new fork with a tapered tube and a 27.5 inch wheel, is there an angled headset for this concoction as well? I just want to slacken the bike, and not necessarily raise the front too much.
Favorite (road) vehicle is the Porsche 959 (or the Audi RS4 avant for the realistic dream). Favorite vehicle of all time is the F-4 Phantom.
Lamborghini Aventador. For sure. But I’m old enough to love the Quattro and yes, incredible Walter Röhrl driving that thing insanely
For tires, CST (a chinese tire brand) owns Maxxis. I won't be surprised if they are made in the same factory. If you want affordable performance, go CST.
my favourite has to be a delta integrale...but your quattro is very much up there!
Favourite Vehicle: Mazda 787b just the sound alone would do it for me
My Rockshox reverb dropper has failed (blown seal) 3 times. I know they make a lot of them, but not a great ratio for me. Brand X Ascend worked flawlessly since day 1 on my other bike.
Favourite vehicle? Cousins old Celica GT4, Mercedes Unimog that my uncle used to gang mow with, my sadly missed XR4i. I could go on....
Shimano 12 speed mechs have a line marked on them to help set the B tension screw. At least my SLX has.
VW Caddy van, can just pop bikes in and out so easy, and it doubles as weekend accommodation, better than a tent!
Obviously a Lancia! Especially the 037, the last rear wheel drive to win the championship before the 4 wheel drives took over indefinitely.
#askgmbntech. I've been looking at a 1993 Marin Pine FRS, and wanted to get your thoughts on fitting modern-ish air fork internals to the original Manitou carcasses, if you will. That way I keep the small axle to crown dimensions, wicked retro looks, and rear fork (shock) compatibility, but get a more progressive and sensitive ride. thanks!
I think air spring will get complicated because the Manitou is an elastomer fork and was never designed to be airtight. I‘d go for coil springs. Doddy had that on an old Rock Shox and it seemed to work good. I don‘t know if there is a hydraulic damper for a Manitou 1 but with such little travel you might get away without one.
@@chrisridesbicycles I was thinking it may be possible to insert an airtight sleeve containing the internals into the fork lowers to keep it airtight, and mucking around with modern seals. It wouldn't normally be an issue for me, who loves OE specced bikes but I want an FRS to actually ride, not just to drool over.
@@judechandler5102 I guess you will have to build much of it from scratch since modern forks have bigger diameters and the internals will not fit into the old Manitou. Good luck though. Send it in if you are successfull. I‘d love to see an old silver-and-anodized Marin in working condition.
It's worth buying good bars & stem for i have snapped many, my worst one was when I got off the train in North Wales for a week of mountain biking, got of train cycled across Barmouth bridge on route to mom & dads place and bang bars snapped, this was about 30 years ago and do you think I could find a replacement.......no spent hole frellin week cycling on the roads with a tree branch as a set of bars which to be fair were bloody great, just didn't trust them on my rock hopper comp as there was a lot of flex due to using willow as would of snapped if anything eles
#AskGMBNTech I bought a new KMC 9s chain because the existing one I'm using is worn out per the chain wear tool. My problem is, the chain skips when pedalling. What bugs me is when the old chain is put back, it doesn't skip. Thanks a million!
Sounds like your cassette is worn aswell. Check the teeth of the cassette, if there not uniform, often looking like a sharks fin, its too worn and should be replaced as well.
If the cassette is worn by the same amount as your chain it will skip less, but you should replace both as not doing so will wear your chainring prematurely.
Maintenance comparison sounds good 👍
Favourite vehicle? A classic Mini. I have one, plus the Lego model, plus the same Audi as you.
Oh and I've had a passenger ride in an ex-works S2 on a rally stage. They are indeed completely bonkers!
My favourite vehicle? Subaru sti 22b. Offroad 4 seater beast.
I have heard that bike discs don’t get hot enough to burn off automotive brake cleaner. I would use bicycle specific brake cleaner.
i got hi pitch squeal from sealed bearing, i checked the bearing inside and i found the grease getting wet, replacing grease or just add more grease on it kill the squeal
I’m on your wavelength Doddy:
Favourite: 1986 Land Rover County V8 (110), parked in my mum’s carport.
Dream: Yeah, something all wheel drive, turbo and 5cyl.
Group B - Ford RS200
Car wise it would have to be either a 1970 Dodge Challenger RT in White (and then people could call me Kowalski) or possibly a Hudson Hornet. But just recently I've learned about the Icon A5 Sport Plane and think I really need one of these (learning to fly might be a bit of a cost).
#favorite Vehicle- 1998 GTS 500 Dodge Viper or Ken Bloc’s Hoonicorn the stuff he does in that is insane!!
#AskGMBNTech hi I'm looking to get a chain guide as I keep dropping chains. I have a jamis Dakar a2 and the chainring is a suntour SR and you can only just see there used to be a wider tooth every 4 teeth.i can't find any more in stock and wouldn't know how to replace it anyway. Can you make a video on how to Identify the chain guide mounting holes and which guide I should buy. Thanks
So for your vehicle question i would choose a BA - 350 wich is a heavely modified Ford F-350 with lots of Suspensiontravel, fat Tires and tunend Diesel Engine. It is big, wide and even halfway practical for lugging Stuff around. If you want to know more about it ask UA-cam for a Video
Sorry to ruin your Group B favourite, but the Audi nemesis: Lancia 037, probably the most beautiful car of the era 😗
Peugeot 205 T16! Absolute mental car if you ask me.
Favourite car . Lancia Stratos.. Nothing else compares.
Audi Quattro you say? Of course, the counter argument would be - Lancia 037! They were so sick!!!
I actually nicknamed my xc ht Lancia 037 😊
Great, informative vid as always. Easy vehicle choice for me. Lowered VW Transporter Sport line. Kitted out for bike and living in. Wales, Fort William, Les Gets.... Oh shit I've just woken up... Oh well😢 keep safe all
I bought my son that same Lego Audi Quattro! Love that car!
My favorite car isn’t a car it’s a truck, a Ford Raptor looks cool and you can carrier bikes too.
This was a really good video thanks.
The one's I own my Kawasaki Concours 1400 and my Kona EV. But I always loved the Subaru Rally cars all blue with yellow.
My favorite vehicle is a Ford raptor 2 door or a stingray corvette 1963 those are super beautiful cars it’s insane
#AskGMBNTech
Hi Doddy.
I will soon be upgrading to my first dual sus mtb.
Watching your video's, you have mentioned using WD-40 to drive out moisture from pivots.
Looking online, I see many people say that WD-40 in pivots is horrible for the bearings.
Could you please school us on when and how to remove moisture safely?
Love your work!
I love shimano and I’ve got a shimano slx 11 speed 11-46 cassette. The cog before the 46 tooth is 37 tooth. Too big a jump imho. The sunrace equivalent has a 40 - 46 jump. Much more usable. In my case I’d prefer the sunrace to the shimano.
"A lunatic that can ride an insane amount of miles for two weeks" sounds like a challenge for Hank from GCN
Sounds like a job for Lachlan Morton
my exact thought :)
