Hi Doddy! I am looking to upgrade my fork on my 2008 Kona Caldera. It has a 100 mm of travel and I am looking to get a longer travel fork. I am most worried about the BB height. The BB height is 300 mm right now. Can you give me some geometry numbers, some suggestions on forks, and what bike group would you categorize it as. Like enduro. #askgmbntech
Hey Doddy & GMBN Tech guys, thanks for featuring my question - I only do basic jibs, 2-foot huck to flats & drops, nothing that extreme (like Blake) so, I really have no clue what happened to those hubs 🤣 Anyway, I already purchased a DT Swiss hub, and it works like magic!
#askgmbntech Hi Doddy, loving the show! When you’re in the middle of 2 bike sizes would you recommend the smaller size adapted to be bigger e.g. with longer stem or a bigger dizer adapted to be smaller, e.g. with a smaller stem? Thanks
Hey GMBN. I've been MTBing since '91 . Cheers Doddy (and the gang) for your weekly show . Even when I can't get out you make me feel I have been . Keep it coming.
I've destroyed two Microspline hubs this year (got warranty on both) on a Yamaha PW-X2 Ebike. The first one was a Shimano Deore hub, this one lasted about 1000km, and then it started creaking like crazy under torque. That was replaced with a Deore XT FH-M8110-B version, which lasted about 20-30km (two rides) before it started creaking. Finally had enough and got a DT Swiss 240 Hybrid hub (reinforced for Ebikes), has about 500km on it now, and still no issues with it. The only issue I had that it required another wheel to be built and a new rotor because it meant going from CL to 6 bolt.
Fork question....remove.volume spacers if ur sag is set correctly, not just drop pressure, as then sag is off effecting the handling in corners and pedalling as well.
Another great video Doddy. I always thought the answer to a Sram/Shimano cockpit was having to use a 22mm clamp for the shifter. Also in answer to the request for a longer dropper post, you're correct that there are quite a few 200mm droppers, including the latest Fox Transfer (although Crank Brothers doesn't seem to be one of them; the Highline maxes out at 170mm). If every millimetre counts, the Oneup Dropper 210mm is probably the best option.
I'm a heavy rider. Both lack of finesse and weight. Every free hub failed until I found DT. Only have had one failure since. 350 way cheaper than 270, same system.
Wasn't using all my travel on my 130 Revelation and it felt harsh over small bumps, more sag just made it feel unsupported. Removed 2 of the 3 factor fit tokens and it felt much better. I've since added the 2021 piston mod and gone to 140 airshaft and removed the last token. I now use a decent amount of travel for the half arsed attempt at aggressive riding I do and it feels pretty good. Still not as good as those slow mo's GMBN have of Neil and Blake sending it down rough sections and the fork just gliding up and down with the bars steady. I'd love me some of that.
From the south of the Philippines here. There's little to none in the way of dedicated bike parks, but the massive countryside is essentially like living in a trail center. Spoilt for choice. More relaxed and friendly attitudes towards bikes and cyclists too as a whole, both for road and mtb. None of the angry cyclist-hating drivers I often read about in Western countries. And no winter riding worries too. Be good to see you guys here (and the GCN crew as well come to think of it). The South has tons of hidden gems, especially because a lot of outsiders think it's dangerous here (generally it's not).
Shimano FH-MT510-B #microspline hub: I have no idea how, but it came loose while taking the rear wheel off my Orbea Laufey 2020, less than a month after purchase. Put it back on, a few rides later it started creaking like crazy, until it got stuck while descending some gnarly trail. I had to get the wheel off, and used the axle to gently unlock it. When I got home I disassembled it, found it was full of oxidation. Cleaned it, re-greased it, creaking was still there, plus one of the pawls developed some slipping, until the whole thing was unusable. Luckily Orbea replaced the whole rear wheel, which i haven’t used yet since while waiting for replacement I pulled the trigger on a pair of Hunt Endurowide, which have made my Laufey more lively especially on the climbs, and a hell of a lot louder on the descent. OEM wheels are 2.6kg heavy, the Hunts are around 2.1, and that’s a difference that can really be felt.
#AskGMBN how much of a difference does a goatlink (derailleur extension) make on the shifting performance? What modifications to the setup would you make if you used one (B tension, H and L screws, cable tension)?
The GoatLink lets you run a larger cassette than the mech is specced for, other than that it makes no difference to shift performance. I installed one so I could run an 11-50 Sunrace cassette with an 11 speed XT mech and it works pretty much flawlessly. Every so often I'll find I can't shift out of 1st and it's because the b tension has released a bit, so I give it a quick tweak and away I go. I should probably throw some loctite on their and fix that problem. In terms limit screws and cable tension it makes no difference. I guess if your derailleur hanger was misaligned it would multiply the issue, but assuming your hanger is straight and true they are great at what they're designed for.
My trail weight is about 110kg and I destroyed a Stan’s Neo hub with microspline within a couple of rides. It literally exploded and all that was left was shattered metal when I took it apart. I was running a 51t cassette but wasn’t even pedalling very hard. I put a Hope Pro4 on after that and it’s been perfect 👌🏼
I have chewed up an xt microspline hub the same way. It lasted 2 months in summer on an ebike. Its away for warranty but there is a problem with them if you search the internet.
Drop a spacer (and remember to add 5psi from your perfect psi) in your fork if you aint doing 10ft hucks to flat. Like Doddy says these modern forks are made for aggressive riding, if your doing light trail/ XC you wont use it all, probably not even the last say 30-35%. Plus any 35mm+ stanchion fork is made to be jumped and dropped hard it's just what they are designed for hence the extra weight. It's just so many people buy a trail bike as a do it all or for learning, when they are intended for much, much more so the forks seem near impossible to use most of the travel.
#GMBNTech #AskGMBNTech Could you do a show on head badges? I find myself fascinated by them. How have they evolved over time? Who has the best one? Is it ok for some companies not to have one? Canyon, for example, simply paint it on....
If I increase the air pressure in the forks to recommended for my weight it never bottoms out but if I reduce the pressure by 10-20psi recommended it can bottom out
You know, in my experience, most dropper posts move a little TOO fast up and down. So using some thicker than normal grease might actually help it behavior in a bit more of a sensible way.
#askgmbntech Having a lot of trouble with forks freezing up & going rigid at temperatures below freezing in the winter rain & snow. Do you have any tips for keeping suspension operational in winter? Will it help to perform lower leg service at all? The forks all feel great whenever the temperatures are above freezing.
It's ovious that the suspension fluids are probably freezing (rebound), but I have no idea how would you prevent that, so it would be interesting knowing that.
Hi Doddy, I've lived in Cambodia for my whole life and only moved to the UK (Bristol) recently, the mountain biking scene there is very big with lots of races taking place. For more enduro and downhill focused stuff, Cambodia isn't really the place and has near to no trails for that. The community is mainly XC orientated but it would be wonderful if you visited :) Regards, Alex
#askgmbntech Hi Doddy, great show as always. Looking to buy my first full face helmet. Could you do a section on how a full face helmet specifically should fit, how much it should actually move when worn? Can’t find any videos that actually demonstrated how much one should move when properly fitted. Examples of good fits and bad fits would be brilliant.
YES. Microspline is absolut sh#,§. The spring on my Newmen hub failed on the FIRST climb. So at 950 metres elevation I was to turn around an make my way to the car with a fixie. And Newmen admit they had quiete a few hubs fail
known issue with Shimano XT microsplines, on Newmans, on the E-mtb Cube Stereo HPC 160. There's a note on Shimano's website for how to resolve the issue. I have had it repaired twice. It's holding now but I went with new Stans/Hope wheels regardless, as more dependable.
I got a set of those cable cherries from Forager Cycles I love them, they are a nice little touch. No more looking for a cable end at the bottom of the bin!
@Mircospline Hubs It looks like there is a lot of grease in there. That would be incorrect maintenance. Freehubs only function correctly with minimal grease. Also the DT Swiss 350 is cheaper and also has the ratchet system. And this issue should be independent of the mircospline system (although I prefer the XD-body)
Yeah that confused me thought all DT Swiss wheels are star ratchet but the 350 does indeed use a 3 pawl system, mine are old style HG hub body so hoping it does not happen on mine but I've heard others (they come OEM on a bunch of entry-mid range trail bikes) say they can strip pretty badly. TF tuned are the DT Swiss reps for the UK I believe so shoot them a message and see if they could rebuild under warranty if authorised (believe its 24 months warranty from new) if OP has it.
@@tommycooperfish the standard 350s should be ratchet. the 370 are 3paw. However you can convert a 370 to ratchet. I guess they use the same outer shell and only the mechanism is diffferent. I personally use 350s since 2015 and never had a problem
@daszenkerle if your fork is seted up with 25% and it feels to firm it could be air trapped in the lowers to remove it let all the air out and then try to move a little de seals and then try to insert a plastic strap i don't know how are they called in english, hope y could help you
#askgmbntech Hello. I am thinking of switching to clips for the season 2022. This year getting new bike (canyon grand canyon 8) and stamp2 pedals and just wanna make sure that clips would be better. I will probably buy new crankbrothers Mallet E shoes (couse I walk a lot off the bike and do a lot of miles on it) and Mallet DH pedals (Superbruni edition. Looks awesome) couse I love bigger platform pedals and feel safer that way. So I just wanna know if that would be "pairable" becouse I am woried thet shoes would just grip to much on the pedals or even won't sit on the pedal the right way. Thank you so much. You are awesome.🤘
Hi Doddy, how are you? Just wonder why can I only measure 135mm of exposed stanchions on a Fox 32 Talas RL OpenBath (2010) that should have maximum travel of 140 mm? It seems to me that I only have 130 mm-ish of useable travel. I read in some online web board and they converted Talas to Float, will that help to regain that lost travel? #askgmbntech BTW, I come from Chiangmai! That trail you were talking about must be at 'Doi Suthep' (the mountain with a temple on the top). They organised international enduro series the year before, maybe you and GMBN folks can go race there when the situation is better.
Hey, watch all your shows, they're the best information on UA-cam for budding mountain bikers. I live in Singapore and if you ever make your way to this party of the world I'd be honored to take you guys to the many tracks we have here. Bukit timah is a mainly 1 black diamond track about 6km long. Then there's pulau ubin, am offshore island with a great single and double black 4km track there. There is also double black track kent ridge, but that tends to be quite horrific in upkeep. There also several km of tracks of single black diamond around chestnut north, with chestnut south being an easy 2km fast track with nice fast zones. There is quite a bit here for such a small island. Only thing you need to worry about is the heat! Exerting yourself in the jungle at usually around 30 degrees isn't as easy as you'd think. Hope you guys can come over, I'll be your host :)
I've destroyed 2 stans hubs since I bought my bike in February. The first one I destroyed the durasync freehub body. One of the pawls snapped and destroyed everything inside. The second time I had a speedsync freehub body and ended up spinning the gear with the teeth on it. Stans has been really good about warranting it but still I've destroyed 2 hubs. No issues since I got a whole new wheel in August. I have a X01 10-50 tooth cassette with a 32T chainring.
Haha I did some of that "bonkers crazy stuff" you mentioned in the late 80's early 90's. I was thick in the middle of it. Good times. Looking back knowing that we pulled it off... doesn't feel so crazy. But it absolutely was. Wish I had all of it on film. Unfortunately we only filmed the large events and it's all registered to one of the power 3.. Cbs, Nbc & Abc here in America and it's all copyrighted material... well accept my very fond memories of it of course. Bonkers indeed...later Doddy.
you can, but the reliability comes from the tire bead-rim interface being optimized. Bodging a tubeless setup will work but has chance of a tire coming off the rim
Philippines is so rich in potential for Mountain biking. we got lots of hilly terrain and yes, mouintains specially in the Island of Luzon. Its a small country. Not bigger than Texas ( In Land area) so start vlogging in a mountain or local trails near you.
Hey Doddy, I'm Waiting for my new Scott Ransom 920 to arrive. So not cannot confirm exactly what is used, however it is specked for SRAM NX Eagle transmission and Shimano M6120 brakes from the factory. And they appear to be mounted on the same clamp. So I suspect Syncros may have what you need to mount SRAM and Shimano on the same integrated clamp, (I also could not confirm this , I don't see any small parts on the site.....)
Can you also discuss how your tune might have to change as the temperature plummets? I had my suspension feeling dialed over the summer. But now when it’s in the 20’s fahrenheit it’s feeling harsh again. Is this a known thing? Do we have to redial it for cold temperatures? If so is it mostly likely the air pressure or the rebound or both? #AskGMBNTech
#askgmbntech how do you know when your problem is a tech issue or technique issue. I have problems keeping my feet on the peddles over jumps The peddles seam to feel like they fall away in the air. I have Shimano GR500 Flat MTB Pedals AU and Giro Jacket II shoes. Is it something to do with my technique or is it something to do with the compatibility of my shoes and peddles?
It's all your technique, flat pedals are not supposed to vertically attach to your shoes, that's the point of not clipping in. You should probably practice pedaling though, since peddling experience doesn't help much on a mountain bike unless you're trying to sell it.
#askgmbntech I know the geometry question has been asked a million times, but could you go in depth as to how proportions that are outside of the norm might affect bike fit? I have a long inseam for my height and a short torso (5'9" and a 33inch inseam). Different bike shops tell me I should both size up and size down with long legs. What I've personally worked out is I need a high stack and reach that's longer than a normal medium but shorter than a normal large. Further, I've found I really like long chainstays but a lot of my shorter legged friends think I'm nuts and love them as short as possible. I'm wondering if there's a reason for that.
#AskGMBNTech even though i land from a very high place i barely use 50% of my travel and the fork is a Marzocchi Jam Comp Its an oil shock and leaks black goo on the Stanchions.
Alright this is not entirely an mountain bike question but do you know of any other products (not even for a bike) use miyaki friction reducing products if you can call them that. Also why do no other suspension companies use a Kashima coat? #askgmbntech
Hi Doddy #askgmbntech I also had an issue with a Shimano XT M8110 microspline freehub on my couple of months old Whyte 909v2 earlier this year. As you probably know this freehub only 'clicks' at lower speeds and is near silent when freewheeling fast. Mine started making intermittently 'clicking' at faster speeds and sounded crunchy (like an un-lubed chain) under load. Bike shop had heard of issues and returned back wheel and another they also had in to Shimano for warranty replacement of the rear hub internals. No probs since (fingers crossed)
#askgmbntech hi doddy, i have a problem with either my riding style or my suspension, it is recommended to run 30% on the rear but that seems so incredibly soft, i bottom that out just by bunnyhopping. To NOT bottom out i need Like 20% but that feels harsh. I have this problem on all bikes i ride. I weigh 70kg btw
#askgmbntech what is the difference between a shock that's mounted upside-down like the new Norco optic and one that's right side up like the trek slash? Any insights into the tune or leverage ratio that makes them want to mount it that way?
Simple: like almost every body else, you bought a bike, which has, if set up correctly, about 2 to 3cm unnecessary suspension for you. So don't worry it's just the way it is.
Because you are not riding hard enough or your fork is severely overpressured. First one is absolutely fine, the second one is something you need to look at it. See? I answered the question.
#askgmbntech why don't we see forks that have more travel then 200mm, it looks like there would be space on the bike for more travel like 220mm or even 250mm
So piggybacking off the question of “why no double crowns?” Why are we not seeing double crown forks with more travel? It seems like the 10mm of extra travel from a single crown to a double crown is practically nothing so why not longer?
Hey Doddy loving the show, am rebuild a 99 Santa Cruz heckler, using modern components but looking to find out what you think the best 1" 1/8 forks are with at least 100mm and preferably 20mm pull through.. Gonna be used for xc, freeride and some mild dh. #AskGMBNTech #askgmbntech
Hey Doddy. Love the show. I’ve been a fan since MTBUK. My everyday ride is just a few metres from my house but it’s a type of clay that packs the tires in five minutes if it rains. Ergo... end of ride. I’ve asked everyone if they have a solution. Your my last resort. Can you help me?
#askgmbntech I have a hardtail mtb, and under certain pedaling conditions (which is unidentifiable), sometimes some component creaks or clicks. Previously I had that was from another bike but that had a loosened bottom bracket. However this new one has no play in the bottom bracket whatsoever. I have reviewed all those identifying videos off of GMBN and GCN, but handle and steering components are solid, as well as seat and rear cassette and hub components. Am I missing somewhere to look for? I am from India and the bike in question is one Montra Rock 1.1 (not popular outside the country I assume).
#askgmbntech Hi, i recently tried to bring my old hardtail back to life, but struggled to get the front derailleur to work properly (despite watching your videos :/). Its a 3x9 deore xt drivetrain with cheaper shimano shifters and a new large chainring on the alivio crankset. Now the problem is, that i cant get the front derailleur to cover all the gears. On the biggest chainring it keeps rubbing against the chain unless i put a lot of tension on the cable. Thats when shifting quality between the smaller gears suffers. What could be the problem? Do some chainrings stand out further and thus increase the distance between the gears? Thanks a lot and merry christmas from Germany!
@ How do I assemble an SLX SL-M7000 I-Spec II 11-speed gear shift lever on a Sram matchmaker. I know several adapter form WOLFTOOTH and ProblemsSolver but i don't know which to choose.
It went together easily in less than an hour. ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Make sure the front fork is forward or the pedals will hit the front tire. Tires are both a little soft so it needs air before I ride it. The rear wheel didn't come with a clamp regular bolts hold it on. The front had the clamp. No scratches out of box. Rims are a little off with a slight wobble. They could have spent more time with the spoke tool fixing the run out. So far out of the box I'm happy with it. I did replace the pedals with a nice aftermarket set. After riding it a bit my A$$ is a bit sore so I ordered another seat. Overall I'm nearly 60 and didn't ride a bike in 30 years. I like my new 29" Schwinn. It will be used for casual rides with my friend.
#GMBNTech #AskGMBNTech Doddy, love the channel and have been a subscriber since day one. What is your take on MTB apparel? Has it progressed at the same pace as bicycle tech? I am finding it difficult these days to get a "minimalist" kit. Any advice on who makes normal trail riding gear with minimal straps, buckles, lightweight and stretch? Thank you!
Hey Doddy, I will be living in a city for a few months, which does not have a lot of good MTB-spots but some pumptracks and Skateparks. I usually ride a lot of downhill in bikeparks, now I still want to be active and ride and I am looking for the best choice of bike for the city for pumptracks, fooling around and just riding around. I like dirt bikes, but I hate it that you cannot ridem them around like a normal MTB. Now I am thinking of getting a hardtail trail bike. Can a hardtail be as much fun as a dirt bike on a pumptrack or in a skatepark ? I am thinking of something like the canyon stoic, which recently came out. #askgmbntech
#askgmbntech I have a 120mm Rock Shox Revelation fork on my 2019 Marin Rift Zone 3 that I cannot get to bottom out on the hardest of rides. I have even taken all of the air out and tried to compress it all the way down..still no dice. I have recently removed 2 of the 4 volume spacers, but the way I understand it, those will only give me a more linear feel in my travel and won't do much to increase or decrease the travel. What else can I do?
#askgmbntech If I were to change my 130mm travel, 51mm offset forks for 150mm travel forks, should I reduce the offset to 42mm so as to counter the slacker head angle? Thanks
#AskGMBNTech I wonder if a mtb with only rear suspension exists and if it does , is it going to be faster when sprinting . Maybe even easier to pedal on the road
#AskGMBNTech Hi Doddy writing this comment again because I forget to tell you that my fork does not have a bottom out line but does on the shock. My question is were is the bottom out line on a fork like the RockShox Lyric. Wondering because on 8 stairs that I jump I do not know if I bottom out because I do not know the bottom out line. Thanks. I love the show!
#askgmbntech I am after my first proper mountain bike, I have found a fair few but some have SRAM Gears and others Shimano which ones better in your opinion?
#askgmbntech i just got a new Trek Slash 8 with a RockShox Super Deluxe Ultimate shock. Here my question: when I push my rear bike suspention fast, there is a little and very quite clicking and sucking noise. It's really quiet but I am super paranoid bc it's my new baby. So is it normal there are quiet sucking noises in ur rear shock?
#askgmbntech i have a schnell coupe 1.0 whose fork is stuck also the pedals are broken i mean i can't use the fork suspension but the bike is very close to me and i love riding it so what should i do should i buy a new bike which i am thinking about buying a trek marlin 5 or should i just replace my forks and pedals
#askgmbntech I am building a nukeproof scout 275 and I have to choose between a rockshox lyrik rct3 160mm and a rockshox lyrik rc dual position 160-135mm. I heard that the dual position one just blasts trough the travel bottoming out. Which one do you think is better and what other recommendations do you have?

I'm a heavy rider. Both lack of finesse and weight. Every free hub failed until I found DT. Only have had one failure since. 350 way cheaper than 270, same system.

Yea I read some bad reviews on the XT hub on JensonUSA and WWC. Seems like the SLX is more robust and almost as many POE
It looks like he packed the freehub with more grease than an 18 wheeler's wheels bearings.
Might be or it just looks like it because it's full of gunk
Drop a spacer (and remember to add 5psi from your perfect psi) in your fork if you aint doing 10ft hucks to flat. Like Doddy says these modern forks are made for aggressive riding, if your doing light trail/ XC you wont use it all, probably not even the last say 30-35%.
Plus any 35mm+ stanchion fork is made to be jumped and dropped hard it's just what they are designed for hence the extra weight. It's just so many people buy a trail bike as a do it all or for learning, when they are intended for much, much more so the forks seem near impossible to use most of the travel.
#GMBNTech #AskGMBNTech Could you do a show on head badges? I find myself fascinated by them. How have they evolved over time? Who has the best one? Is it ok for some companies not to have one? Canyon, for example, simply paint it on....
If I increase the air pressure in the forks to recommended for my weight it never bottoms out but if I reduce the pressure by 10-20psi recommended it can bottom out
You know, in my experience, most dropper posts move a little TOO fast up and down. So using some thicker than normal grease might actually help it behavior in a bit more of a sensible way.
Cheers great video will put that right into action
You should try Phat tire adventures in Dalat, Vietnam, you will enjoy that area!
#askgmbntech Having a lot of trouble with forks freezing up & going rigid at temperatures below freezing in the winter rain & snow. Do you have any tips for keeping suspension operational in winter? Will it help to perform lower leg service at all? The forks all feel great whenever the temperatures are above freezing.
It's ovious that the suspension fluids are probably freezing (rebound), but I have no idea how would you prevent that, so it would be interesting knowing that.
Interesting that air pressure comes up again. I think because it's important. Always will be. Good vid, great info. Thanks sir. 🙋
Hi Doddy,
I've lived in Cambodia for my whole life and only moved to the UK (Bristol) recently, the mountain biking scene there is very big with lots of races taking place. For more enduro and downhill focused stuff, Cambodia isn't really the place and has near to no trails for that. The community is mainly XC orientated but it would be wonderful if you visited :)
Regards,
Alex
Another cool Q and A session Doddy 👍😎 cheers
#askgmbntech Hi Doddy, great show as always. Looking to buy my first full face helmet. Could you do a section on how a full face helmet specifically should fit, how much it should actually move when worn? Can’t find any videos that actually demonstrated how much one should move when properly fitted. Examples of good fits and bad fits would be brilliant.
Easy fix....Get some fox 40's!! :D

Hi again
Damn you are everywhere

YES. Microspline is absolut sh#,§. The spring on my Newmen hub failed on the FIRST climb. So at 950 metres elevation I was to turn around an make my way to the car with a fixie. And Newmen admit they had quiete a few hubs fail
known issue with Shimano XT microsplines, on Newmans, on the E-mtb Cube Stereo HPC 160. There's a note on Shimano's website for how to resolve the issue. I have had it repaired twice. It's holding now but I went with new Stans/Hope wheels regardless, as more dependable.
Destroyed a Shimano deore microspline after only 2 rides. Switched to a Stan’s micro hub and no problems after thrashing it for 2weeks
I got a set of those cable cherries from Forager Cycles I love them, they are a nice little touch. No more looking for a cable end at the bottom of the bin!
always great advice! thanks!
@Mircospline Hubs
It looks like there is a lot of grease in there. That would be incorrect maintenance. Freehubs only function correctly with minimal grease.
Also the DT Swiss 350 is cheaper and also has the ratchet system.
And this issue should be independent of the mircospline system (although I prefer the XD-body)
Yeah that confused me thought all DT Swiss wheels are star ratchet but the 350 does indeed use a 3 pawl system, mine are old style HG hub body so hoping it does not happen on mine but I've heard others (they come OEM on a bunch of entry-mid range trail bikes) say they can strip pretty badly.
TF tuned are the DT Swiss reps for the UK I believe so shoot them a message and see if they could rebuild under warranty if authorised (believe its 24 months warranty from new) if OP has it.
@@tommycooperfish the standard 350s should be ratchet. the 370 are 3paw.
However you can convert a 370 to ratchet. I guess they use the same outer shell and only the mechanism is diffferent.
I personally use 350s since 2015 and never had a problem
Regarding the short travel dual crown fork, what immediately jumped to mind was the Rond WP forks
Ohlins now have their dh fork that goes down to 120mm if you want to
@@ApostolosK06 I am sure, but the ones I am referring to had like 75mm. Which was a downhill fork back then
@daszenkerle if your fork is seted up with 25% and it feels to firm it could be air trapped in the lowers to remove it let all the air out and then try to move a little de seals and then try to insert a plastic strap i don't know how are they called in english, hope y could help you
Maybe it could have some tokens or volume spacers
#askgmbntech Hello. I am thinking of switching to clips for the season 2022. This year getting new bike (canyon grand canyon 8) and stamp2 pedals and just wanna make sure that clips would be better. I will probably buy new crankbrothers Mallet E shoes (couse I walk a lot off the bike and do a lot of miles on it) and Mallet DH pedals (Superbruni edition. Looks awesome) couse I love bigger platform pedals and feel safer that way. So I just wanna know if that would be "pairable" becouse I am woried thet shoes would just grip to much on the pedals or even won't sit on the pedal the right way.
Thank you so much. You are awesome.🤘
4:15 SURYC69 asks for a Sram Brake to Shimano Shifter adaptor. Doddy proceeds to show an adaptor exactly the other way around 😂
Hi Doddy, how are you? Just wonder why can I only measure 135mm of exposed stanchions on a Fox 32 Talas RL OpenBath (2010) that should have maximum travel of 140 mm? It seems to me that I only have 130 mm-ish of useable travel. I read in some online web board and they converted Talas to Float, will that help to regain that lost travel? #askgmbntech
BTW, I come from Chiangmai! That trail you were talking about must be at 'Doi Suthep' (the mountain with a temple on the top). They organised international enduro series the year before, maybe you and GMBN folks can go race there when the situation is better.
Air in lowers causing suck down. Use cable tie down seals method
Im from the Philippines 🇵🇭! I love GMBN.😊🤙🏽
Any good trails there ?
Droppers post maintenance, Super Lube works great
Hey, watch all your shows, they're the best information on UA-cam for budding mountain bikers. I live in Singapore and if you ever make your way to this party of the world I'd be honored to take you guys to the many tracks we have here. Bukit timah is a mainly 1 black diamond track about 6km long. Then there's pulau ubin, am offshore island with a great single and double black 4km track there. There is also double black track kent ridge, but that tends to be quite horrific in upkeep. There also several km of tracks of single black diamond around chestnut north, with chestnut south being an easy 2km fast track with nice fast zones. There is quite a bit here for such a small island.
Only thing you need to worry about is the heat! Exerting yourself in the jungle at usually around 30 degrees isn't as easy as you'd think. Hope you guys can come over, I'll be your host :)
I've destroyed 2 stans hubs since I bought my bike in February. The first one I destroyed the durasync freehub body. One of the pawls snapped and destroyed everything inside. The second time I had a speedsync freehub body and ended up spinning the gear with the teeth on it. Stans has been really good about warranting it but still I've destroyed 2 hubs. No issues since I got a whole new wheel in August. I have a X01 10-50 tooth cassette with a 32T chainring.
Haha I did some of that "bonkers crazy stuff" you mentioned in the late 80's early 90's. I was thick in the middle of it. Good times. Looking back knowing that we pulled it off... doesn't feel so crazy. But it absolutely was. Wish I had all of it on film. Unfortunately we only filmed the large events and it's all registered to one of the power 3.. Cbs, Nbc & Abc here in America and it's all copyrighted material... well accept my very fond memories of it of course. Bonkers indeed...later Doddy.
#askgmbntech. Hi Doddy! Can you convert any bike to tubeless without buying tubeless ready wheels, and just using tubeless tape on lower spec ones?
you can, but the reliability comes from the tire bead-rim interface being optimized. Bodging a tubeless setup will work but has chance of a tire coming off the rim
Philippines is so rich in potential for Mountain biking. we got lots of hilly terrain and yes, mouintains specially in the Island of Luzon. Its a small country. Not bigger than Texas ( In Land area) so start vlogging in a mountain or local trails near you.
Hey Doddy, I'm Waiting for my new Scott Ransom 920 to arrive. So not cannot confirm exactly what is used, however it is specked for SRAM NX Eagle transmission and Shimano M6120 brakes from the factory. And they appear to be mounted on the same clamp. So I suspect Syncros may have what you need to mount SRAM and Shimano on the same integrated clamp, (I also could not confirm this , I don't see any small parts on the site.....)
Can you also discuss how your tune might have to change as the temperature plummets? I had my suspension feeling dialed over the summer. But now when it’s in the 20’s fahrenheit it’s feeling harsh again. Is this a known thing? Do we have to redial it for cold temperatures? If so is it mostly likely the air pressure or the rebound or both? #AskGMBNTech
#askgmbntech how do you know when your problem is a tech issue or technique issue. I have problems keeping my feet on the peddles over jumps The peddles seam to feel like they fall away in the air. I have Shimano GR500 Flat MTB Pedals AU and Giro Jacket II shoes. Is it something to do with my technique or is it something to do with the compatibility of my shoes and peddles?
It's all your technique, flat pedals are not supposed to vertically attach to your shoes, that's the point of not clipping in. You should probably practice pedaling though, since peddling experience doesn't help much on a mountain bike unless you're trying to sell it.
trickstuff does mix adapters too
freeride just means you're free to ride what you want, how you want, no rules
Just the way life should be!
GMBN should try Malaysian trails sometime, we got some nice dh trails here, one of the best in southeast Asia
#askgmbntech
I know the geometry question has been asked a million times, but could you go in depth as to how proportions that are outside of the norm might affect bike fit? I have a long inseam for my height and a short torso (5'9" and a 33inch inseam). Different bike shops tell me I should both size up and size down with long legs. What I've personally worked out is I need a high stack and reach that's longer than a normal medium but shorter than a normal large. Further, I've found I really like long chainstays but a lot of my shorter legged friends think I'm nuts and love them as short as possible. I'm wondering if there's a reason for that.
#AskGMBNTech even though i land from a very high place i barely use 50% of my travel and the fork is a Marzocchi Jam Comp Its an oil shock and leaks black goo on the Stanchions.
Needs a professional overhaul!
Alright this is not entirely an mountain bike question but do you know of any other products (not even for a bike) use miyaki friction reducing products if you can call them that. Also why do no other suspension companies use a Kashima coat? #askgmbntech
Hi Doddy #askgmbntech I also had an issue with a Shimano XT M8110 microspline freehub on my couple of months old Whyte 909v2 earlier this year. As you probably know this freehub only 'clicks' at lower speeds and is near silent when freewheeling fast. Mine started making intermittently 'clicking' at faster speeds and sounded crunchy (like an un-lubed chain) under load. Bike shop had heard of issues and returned back wheel and another they also had in to Shimano for warranty replacement of the rear hub internals. No probs since (fingers crossed)
Darcy Hennessey Turenne. Just mention Dary's new name and you'll be outta trouble, Doddy!
I’ve got manitou circus comp forks and they’ve never bottomed out because they’re stiff af even in the softest setting it’s like a air fork locked out
#askgmbntech hi doddy, i have a problem with either my riding style or my suspension, it is recommended to run 30% on the rear but that seems so incredibly soft, i bottom that out just by bunnyhopping. To NOT bottom out i need Like 20% but that feels harsh. I have this problem on all bikes i ride. I weigh 70kg btw
Add low-speed compression damping on the 30% sag air pressure. Try an intermediate pressure too, like 25% or so.
Doddy with a mustache is both intriguing and disturbing. Honestly.
I'm from the PH, and the city I'm in doesn't have much trails for mtb-ing :
9:04 i'm guessing that might be a giant trance
come here guys indonesia.. and maybe guys you try bikepark gunung pinang.. in indonesia..
Doddy wolftooth does shimano/sram adapters, cheers from Colombia
#askgmbntech what is the difference between a shock that's mounted upside-down like the new Norco optic and one that's right side up like the trek slash? Any insights into the tune or leverage ratio that makes them want to mount it that way?
Simple: like almost every body else, you bought a bike, which has, if set up correctly, about 2 to 3cm unnecessary suspension for you. So don't worry it's just the way it is.
#askgmbntech Would you ride Lady Cannings and Greno woods in Sheffield in a video?
#askgmbntech if the 27.5 tire is lighter than a 29er why don’t xc racers go with a mullet or reverse mullet so they can pinch a few grams
Happy New year my dear friend 🥰
Because you are not riding hard enough or your fork is severely overpressured. First one is absolutely fine, the second one is something you need to look at it. See? I answered the question.
#askgmbntech why don't we see forks that have more travel then 200mm, it looks like there would be space on the bike for more travel like 220mm or even 250mm
So piggybacking off the question of “why no double crowns?” Why are we not seeing double crown forks with more travel? It seems like the 10mm of extra travel from a single crown to a double crown is practically nothing so why not longer?
Hey Doddy loving the show, am rebuild a 99 Santa Cruz heckler, using modern components but looking to find out what you think the best 1" 1/8 forks are with at least 100mm and preferably 20mm pull through.. Gonna be used for xc, freeride and some mild dh. #AskGMBNTech #askgmbntech
Can you show off your nukeproof mega?
Hey Doddy. Love the show. I’ve been a fan since MTBUK. My everyday ride is just a few metres from my house but it’s a type of clay that packs the tires in five minutes if it rains. Ergo... end of ride. I’ve asked everyone if they have a solution. Your my last resort. Can you help me?
#askgmbntech I have a hardtail mtb, and under certain pedaling conditions (which is unidentifiable), sometimes some component creaks or clicks. Previously I had that was from another bike but that had a loosened bottom bracket. However this new one has no play in the bottom bracket whatsoever. I have reviewed all those identifying videos off of GMBN and GCN, but handle and steering components are solid, as well as seat and rear cassette and hub components. Am I missing somewhere to look for? I am from India and the bike in question is one Montra Rock 1.1 (not popular outside the country I assume).
#askgmbntech
Hi, i recently tried to bring my old hardtail back to life, but struggled to get the front derailleur to work properly (despite watching your videos :/).
Its a 3x9 deore xt drivetrain with cheaper shimano shifters and a new large chainring on the alivio crankset. Now the problem is, that i cant get the front derailleur to cover all the gears. On the biggest chainring it keeps rubbing against the chain unless i put a lot of tension on the cable. Thats when shifting quality between the smaller gears suffers. What could be the problem? Do some chainrings stand out further and thus increase the distance between the gears?
Thanks a lot and merry christmas from Germany!
@ How do I assemble an SLX SL-M7000 I-Spec II 11-speed gear shift lever on a Sram matchmaker. I know several adapter form WOLFTOOTH and ProblemsSolver but i don't know which to choose.
@askgmbntech why do my brand new rockshox forks make a squelchy and sucking noise.and my lockout doesnt seem to change anything
It went together easily in less than an hour. ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L Make sure the front fork is forward or the pedals will hit the front tire. Tires are both a little soft so it needs air before I ride it. The rear wheel didn't come with a clamp regular bolts hold it on. The front had the clamp. No scratches out of box. Rims are a little off with a slight wobble. They could have spent more time with the spoke tool fixing the run out. So far out of the box I'm happy with it. I did replace the pedals with a nice aftermarket set. After riding it a bit my A$$ is a bit sore so I ordered another seat. Overall I'm nearly 60 and didn't ride a bike in 30 years. I like my new 29" Schwinn. It will be used for casual rides with my friend.
#GMBNTech #AskGMBNTech Doddy, love the channel and have been a subscriber since day one. What is your take on MTB apparel? Has it progressed at the same pace as bicycle tech? I am finding it difficult these days to get a "minimalist" kit. Any advice on who makes normal trail riding gear with minimal straps, buckles, lightweight and stretch? Thank you!
New Watch?
#askgmbntech. How to pump your rear suspension
Shock pump
Hey Doddy, I will be living in a city for a few months, which does not have a lot of good MTB-spots but some pumptracks and Skateparks. I usually ride a lot of downhill in bikeparks, now I still want to be active and ride and I am looking for the best choice of bike for the city for pumptracks, fooling around and just riding around. I like dirt bikes, but I hate it that you cannot ridem them around like a normal MTB. Now I am thinking of getting a hardtail trail bike. Can a hardtail be as much fun as a dirt bike on a pumptrack or in a skatepark ? I am thinking of something like the canyon stoic, which recently came out. #askgmbntech
I would like to put a galfer 246mm rotor on my motion France fork, but can't find an adaptor for it. Can you help?
#askgmbntech I have a 120mm Rock Shox Revelation fork on my 2019 Marin Rift Zone 3 that I cannot get to bottom out on the hardest of rides. I have even taken all of the air out and tried to compress it all the way down..still no dice. I have recently removed 2 of the 4 volume spacers, but the way I understand it, those will only give me a more linear feel in my travel and won't do much to increase or decrease the travel. What else can I do?
#askgmbntech If I were to change my 130mm travel, 51mm offset forks for 150mm travel forks, should I reduce the offset to 42mm so as to counter the slacker head angle? Thanks
#AskGMBNTech can you change any bike to an mullet bike or on some will the changes to the geometry make it unrideable
Too bad you couldn’t use the actual footage of the guys in BC inventing free ride. The Moment documents it all.
JOHN JEDD please send doddy those failured hubs :D
#AskGMBNTech I wonder if a mtb with only rear suspension exists and if it does , is it going to be faster when sprinting . Maybe even easier to pedal on the road
#AskGMBNTech Hi Doddy writing this comment again because I forget to tell you that my fork does not have a bottom out line but does on the shock. My question is were is the bottom out line on a fork like the RockShox Lyric. Wondering because on 8 stairs that I jump I do not know if I bottom out because I do not know the bottom out line. Thanks. I love the show!
Its the top of the stanchion...or a few mm from the top for latest ones
#askgmbntech I am after my first proper mountain bike, I have found a fair few but some have SRAM Gears and others Shimano which ones better in your opinion?
#askgmbntech i just got a new Trek Slash 8 with a RockShox Super Deluxe Ultimate shock. Here my question: when I push my rear bike suspention fast, there is a little and very quite clicking and sucking noise. It's really quiet but I am super paranoid bc it's my new baby. So is it normal there are quiet sucking noises in ur rear shock?
#AskGMBNTech
what is the perfect size for a bike shed including a bike stand and cupbords any help would be awsome thnx
#askgmbntech i have a schnell coupe 1.0 whose fork is stuck also the pedals are broken i mean i can't use the fork suspension but the bike is very close to me and i love riding it so what should i do should i buy a new bike which i am thinking about buying a trek marlin 5 or should i just replace my forks and pedals
#askgmbntech I have a rockshox pike and the threads on my rebound adjuster bolt are stripped and I’m not sure how to get it out. Any ideas?
#askgmbntech I am building a nukeproof scout 275 and I have to choose between a rockshox lyrik rct3 160mm and a rockshox lyrik rc dual position 160-135mm. I heard that the dual position one just blasts trough the travel bottoming out. Which one do you think is better and what other recommendations do you have?
