My Manitou Mattoc forks have recently started to make a slushy noise, like stepping into sludge when compressed. The fork is maybe half a year old so not really overdue for a service, is that something to worry about?
#askgmbntech Hi guys my forks have started making a shaking sound when ever I put the front brakes on its like my stanchions are shaking inside the lowers of my forks. should I get it checked out?
#AskGMBNTech, Hi guys. I’ve recently got a MTB and have considered going tubless. Can I set my current wheels up as tubless given the inner tubes in there now are schrader valves, and therefore a wider valve hole than a Presta valve would be? Thanks a lot.
#AskGMBNTech Hi guys, love all things tech related, so fascinating! I have recently purchased a Vitus Mythique 27 VRS, i wobble the rear wheel yesterday as something felt wobbly, and there was a slight nocking noise. I had done a full bolt check before to make sure that everything was tight. The bike was removed off CRC recently, is that an indication that the bike is faulty? Thanks.
Thank you for the time stamps. It makes getting to information so much better and less time consuming then sitting through a bunch of information I don't need at the moment.
Didnt actually expect an answer, so THANK YOU! Unfortunately, i had to sell the Trek, as the frame was trash. BUT i did just buy a new Canyon Spectral AL 5.0. Crisis averted!
it was trash for sure, I had two of the same bike, in 17.5/18.5, it was flexy and hanger bent just by riding it. but frame size, and rider weight plays a role too, at 86kg with all gear on it was too flexy for me.
I struggled with an arm pump. Decided to do indoors boulder climbing during off season for fun. Found out my forearms, palms and fingers got a lot stronger and it translated to not feeling the arm pump so quickly. Pull ups are great for arm strength.
Thanks for answering my question! I'll probably stick with middle of the road headsets since I don't ride super hard and would rather spend that extra money on something that I can feel when I'm riding.
Henry mentioned the bearing tolerance difference between a cheap vs an expensive headset which is a factor. However an even more important and often overlooked factor when it comes to bearing performance is material grade and quality. Good quality precision bearings basically require the Rolls Royce of high grade / high purity "Bearing" steels which are made from raw ore and alloying elements with very few inclusions or impurities. Whereas cheap bearings are often made with shitty recycled steel that can have any number of random impurities. To give a real world analogy a ball rolling over an impurity near the surface of a bearing race is like a race car driving over a speed bump on an otherwise smooth racetrack. If you hit it in the right spot at the right speed or hit it too many times in the same spot it could cause a catastrophic failure. In the world of bearings, MTB applications are very low speeds with low cycles so a middle of the road headset is probably a good bet for moderate use. They probably won't be using the purest steels in the bearings but it will still be exponentially better than a cheap low quality steel that may be used in low cost headsets.
I had an FSA Pig open bearing headset on my Banshee Scream. Never serviced it and it was on there for 15 years before I sold the frame. If I dropped the forks out of the crowns (Monster T) the bars would stay wherever I put them, it was that gritty. However, with the forks in I couldn't feel any of the grittiness. It was never loose so that's just the way I kept it :)
Back in the early 90's when steerer tubes were threaded I got so fed up with constantly tightening the headset on my Saracen Trekker that I splashed out £50, a considerable amount back then, for a Mavic locking headset. It was worth every penny too.
Just had to replace my oe fsa headset (nasty exposed bearings), as it went rusty within the year. I bought a Nukeproof top for £20, and it's a million time better - sealed bearings and a rubber seal. The bottom is a Hope external £30, and it's another leap ahead, with sealed bearings and rubber seals.
@@maximilianpult4016 I don't think you can just swap the bearing type, I think you need to swap the race/cup too. Chances are that if the exposed bearings have gone bad, they will have damaged the cup they sit in to. So you will need to get the whole thing anyway.
For dropper cost "contraction" - couldn't you add some sort of spacer inside to limit the travel? I don't know about this one in particular, but I had a similar problem installing a 9Point8 dropper on a fat bike and the company has some spacers that reduce the travel at the top - so your maximum extension is limited. In my case I lost 20 mm of height, which came in handy when I wanted to change saddles.
Jakub, if you don't care much about aesthetics and just want to temporarily achieve proper saddle height, you can create a bodgy 'limiter' to the dropper post by tying a thick string (like a shoelace) from the saddle rails to your seat collar or seat-tube. Set the string length in such a way that it'll stop the dropper post to the 'ideal' saddle height. As I said, it ain't pretty nor permanent, but it's a legit bodge until you can buy the suitable dropper post length.
For arm/hand fatigue - try tweaking your shocks. If the rebound is too slow, a big hit to the fork will absorb a lot but then subsequent bumps could feel really rough if the shock isn’t resetting quickly enough. That’s helped me with hand fatigue
@will bennett - have a listen to the downtime podcast from 19th November 2019 with Laura Robson, the Syndicate Physio - she talks quite a bit about arm pump - a lot of it is core strength and bike position rather than the usual change your grips and move your brakes
The best way to pick a dropper length if you are unsure, is to see what size the bike has from the factory and get that length. Thats what Ive done on two bikes and never had an issue. For the arm pump get a set of revgrips. I had arm pump problems but not anymore. Those are the only grips Ill run.
I had the problem with my 150mm dropper being slightly too high on my large YT jeffsy and didn’t want to drop to a 125. It was aluminum so I used a pipe cutter and cut 25mm out of my seat tube if it’s bottoming out on the seat tube and it works perfect!
Won't work on this particular frame due to the insert design of the seat tube. Did you double check for *clearance* (saddle-rear tire) when bottoming out your shock before cutting or did you just wing it?!
#AskGMBNTech Bike Geometry Question Why are the GEO measurements not given with weight or SAG applied on the bike, be it full SUS or Hard Tail ? For eg. wouldn't Stack height, BB height (or drop) or even chain stay length measurements be affected when recommended SAG is applied? Given different rear ends have different travel paths could applied SAG even change in the overall wheel base, especially with very slack head tubes with long travel forks and certain rear linkage? Also as another eg. an aggressive HT with a 150-170mm fork, when 20 -30% sag is applied that can be up to almost 40mm less than its resting height won't that make the Stack height dramatically less and make the head tube angle steeper just by getting on it? Thanks in advance.
#AskGMBNTech I tried to set-up my wheels tubeless and they leaked air from the join could this mean that my rims are damaged and if so do they need replacing? Also how do you increase small bump sensitivity on an air fork?
No you just likely have sleeved wheel. You need to tape it better. Small bump sensitivity: assuming you don't have an upper level for the best solution is to upgrade the damper assembly. If you have a decent fork you might be able to adjust the damper settings and or change the shim stack in the damper. On a longer travel fork a volume spacer in the air spring may help.
Are they tubeless rated rims? Then they shouldn't leak => return them! If not try using wider tubeless tape, reaching well into the grooves where the beads of the tire gonna sit. Soldering (and sanding smooth!) the joint from the inside worked for me as well.
9:10 bike sizing is a important thing, having too short reach might result in arm pump, having too low cockpit, having brake levers at a steep angle, but with too short reach you can't have them flat, cus that would make it painful , at put wrist at an extreme angle. So long enough reach, having brake levers flat, results in relaxed upper body and arms, it makes a huge difference I went from a way too short bike to a Geometron G1 Large, which fits me properly. New bike is not always the right answer, but sometimes it actually is if it's a reach issue, you need a new frame. also for hand pump, keep in mind if you use mechanical brakes the return spring might be so strong that it's heavier to press the lever, that's something I noticed, my fingers were fatiguing faster, I switched back to hydraulic, but then switched back to mechanical, but my fingers no longer were fatiguing, so that's due to my fingers being stronger probably due to a lot of more braking and working out. Another thing to check is if you have issues with joint misalignment, this can cause movement restrictions, arm pump. So if you have these issues and use too narrow handlebar your elbow , shoulder might pop easier, misalignment, but also if you ride very technical terrain and move a lot it can happen too, but with a too narrow handlebar it will happen very often. These are issues I suffer from. I also have very floppy wrists, which means it can pop up and down, and I can temporarily lose the power and full range of movement in the index finger, so I missed turns cus I could not brake properly. but I have resolved this with wrist supports on both wrists, I use Troy Lee Designs WS 5205 Wrist Support. It has reduced the play in the wrist, and has eliminated the braking problems. of course there is still some slight misalignment but nothing major that hinders riding, so just easy pop to pop it back, but the issue I had before was so bad it could be felt, and heard sometimes. But as mentioned in this video, you might have different problem, that might not be fixed with these methods and might be some internal problem in the arms.
I think that forearm workouts could help a lot if you are experiencing arm pump and you've already tried with different grip ticknesses and brake lever angles. I've found that calisthenics helps to solve a lot of riding issues.
#askgmbntech I have quite violent vibration through my fork lowers under progressive braking. Usually going downhill on roads/fireroads. The forks are 2015 Fox talas 110/140. If I tighten my headset anymore it effects my steering. Running slx front brake with a shimano 203 rotor. Should I be worried my forks are about to fall apart?
Carbon bars over alloy will help with arm pump. The carbon absorbs a bit of the front end chatter. Nothing major but I does help. Curious if anyone knows how titanium bars do in this department?
I have a 2018 cannondale hardtail that I've been gradually upgrading (1-by conversion, dropper post, wide-range rear cassette), and next on my list is a fork. I currently have a decent 100mm straight-steerer coil and I'd like to slack it out with some more travel and upgrade to air, but all of the forks I have looked at have tapered steerers. The head tube has the shape and spacing for tapered forks, but the stock fork is a straight tube, and the stock headset is a 1 1/8 inch semi-integrated (I don't know the exact model but I will be checking on it soon). Will I need to buy something like the Cane Creek 40 EC44/40 Bottom Headset in order to run a tapered fork (or something else for that matter)? #AskGMBNTech
On the arm pump, I'd suggest trying reduced high speed compression damping or getting a better fork that doesn't spike so much if this is the issue. Also Powerballs are good for hand strengthening.
To the dude with the Trek Fuel EX and stem length question, I have a 2016 Fuel EX 27.5 and found that the stem was too long and bar too narrow as well. I replaced the stem with a 42mm one and added 750mm bars. The handling was all over the place and the bike just didn't feel rigt, pretty shit to be completely honest. I've since bought a 55mm stem with 780mm bars and the bike feels and handles sooo much better. It's not an exact science and you'll just have to find what works for you unfortunately
#AskGMBNTech Do you guys know of any good quality discreet GPS tracking devices that I can mount somewhere on my bike? I just spent a big chunk of change on a custom Santa Cruz Bronson build and I'm a little bit paranoid since my last bike was stolen. I know some GARMIN trip computers have a tracking feature but a smart thief could recognize it, rip it off and discard it. Currently I have a Tile Sticker tracking device mounted but it only works if another tile user is nearby and does not have GPS functionality so I'm not sure how well it will work in rural areas.
#AskGMBNTech . My nephew has a Raleigh Tokul 24. Comes with a Shimano Tourney 7spd derailleur. It does not have a clutch so he gets a ton of chain slap and noise when landing jumps (even with rubber on chain stays). Any ideas on a direct derailleur replacement/upgrade or other means of decreasing the chain slap?

#AskGMBNTech I got a new 2020 cube jump bike and recently the forks are moving back and forward when I use the back brake what is the cause of this and how can I fix it.
#AskGMBNTech My front wheel moves in fork dropouts when I brake hard on my front brake, it's the left side that moves down a bit. I tried doing the quick release really tight but that didn't work. I would appreciate some help with this especially giving the importance of the front wheel.
Thankyou soo much for the reply Henry have some new pads on order going to fort William in 2 weeks if sturgeon lets us in so will have an experiment with brake / bar angles hope fully won’t come to seeing a doctor but we will have to see 😂
#AskGMBNTech I've been a paintball player for the better part of two decades, as a result, I have heaps of DOW33 grease.

#AskGMBNTech hi, i have a 2015 cube stereo 140 with 2015 140mm fox 32, the air cap on the top has a plastic tube on the bottom of the cap which means i cant fit volume spacers and i would like to. i believe the only option to be to get a new, 2020 top aircap. what are your thoughts on this and any other suggestions. thanks!
@Jakub Augustynowicz try removing some of the stufing in the saddle to bring you back down to 10-20mm, or look at the nukeproof saddle the dh one not much padding in it and kinda hard but should work for you cost about 25 uk pounds
or he could actually order a new one and bodge his current one while waiting by limiting the stroke with a shoelace tied from the saddle rails to the seat tube.
#AskGMBNTech i have a trek x-caliber 8 2020 model,and i wanted to change the current fork from 100mm to 120mm-130mm,but when i ask trek's helpline,they say i should stick with the current fork. so why can i not change it to a longer fork on a xc-bike? and how do i know if a hardtail can fit a fork that is 120-140mm of travel?
#AskGMBNTech I have a 6 month old Canyon Strive and then I'm putting pressure on the pedals there is a cracking sound coming from either the bottom bracket area or the rear wheel area. Also when im putting my front wheel against a wall and but pressure on the pedals the bottom bracket flexes like 5mm to one side. Is this flex normal and did i just get unlucky with the bottom bracket or could the cause for this be a crack in my frame.
Well probably the bottom bracket which is easy to change or if you're really unlucky the bottom bracket shell is out of spec ( crappy tollerence, hole Misaligned or the hole are not quite round) and if the shell is out of spec you're only solution is a warranty claim .

#AskGMBNTech: Hi thank you guys for this show. We gotta know a lot of things from this. Good luck. By the way, I have a bike with a 3X chainring (saiguan 42T) and 7X Cassette (suangin TZ). The problem is when I put the chain to the largest chainring and the smallest cassette, it starts to slip ( no impact on other gears). So, can you please give advice on this problem
@@doncrescas Dude said largest chainring + smallest sprocket = no cross chaining here! Where is it slipping - in the front or the rear?! Check for worn drivetrain. _(cassette and/or chain)_ Maybe try re-adjusting your b-tension screw (get the upper jockey wheel closer to the cassette) as well. After that LBS/new parts.
#AskGMBNTeck I've got a 2017 skott aspect 950 and it's running an 80$ santour fork. It's good for xc but I want to do more aggressive riding. Is it worth upgrading to a better one? I am going to get a new bike in the next few years.
They are designed to bottom out sometimes so no but yes if you have way too little pressure! Usualla suspensions have rubber bump stops that take the hit if you bottom out so metal doesn't hit metal because then something could break
Anybody have a problem putting air in they're front fork. It is a 2017 Rockshox Pike and it takes air but barely and it does not seem like it ever get enouph at all. Thanks

#askGMBNTech What are the differences between changing the stem angle and changing the number of spacers on the headset, in order to change the height of handlebars? Would the two options perform/feel different?
Assuming the distance from the handlebars to the stearer tube were the same it won't matter. However the short stems that are now common tend to have no rise. The other option is to get handlebars with more rise.
hi there @GMBN TECH i have a request if i may, i am looking to build up an alloy frame muddy fox storm and was wondering if Doddy or any of the guys may have some old spares they may be willing to donate. i am running a 26" wheel at the minute with a 21 speed set up and disk brakes, tho would like to change the crank set to give me a bit more ground clearance as i like to go through dirt tracks with some high stumps. my main issue is the shocks, as the front forks are really bad for bottoming out and the way they spring back is brutal. the rear shock is a standard 750LBS IN and it is a bit too solid for my weight as im only 9 stone, trust me it does not make for a comfortable ride. i could probably change the saddle to help with the comfort but would need to take a look through your review videos for some tips when picking the right one for me. any assistance that can be offered will be greatly appreciated and i would be more than happy to send pics and or video of the work being complete and some time spent in the dirt tracks here in glasgow scotland.
@ Hi, love the content, been trying to get in since months. I am in market for a new bike. The bikes in my budget are all hardtails. the 2 bikes I have shortlisted to. The GT is 1 degree slacker and 10mm longer reach, while the Polygon has 20mm more travel with a better model fork. Rest of the spec is similar. I ride enduro mainly, on rocky trails, What would be better for me? #AskGMBNTech
#askgmbntech I have had a nightmare of a time keeping derailleurs going for more than a few rides. NX, GX, XO1, Shimano, it doesn't matter; they always blow out or bend or pop out from under me. Riding with some very good people I have been told my shifting technique is spot on. At 220lbs, am I just too heavy of a person for aggressive riding? This has caused me to look into gearboxes. A common complaint with them is drag/friction. Has anyone tried isotropic finishes on the gears to reduce this? Looking for a good fix to stay on the trails!
@@Bpf1893 yes, i purchased the park tool hanger straightening tool and have had shops straighten/replace it i don't one how many times. That is also a recurring problem.
Yes and you’ll have a ton of fun! But you probably won’t be winning any races. I’d say 130-150 for fun-focused jovial riding and 160-180 if you’re looking for a serious speed sled to just barrel through the features. Go for the former if you climb most of what you ride and go for the latter if you shuttle/chairlift and/or plan to race at all. I’m on 145 rear, 150mm front and find it’s more than capable of crushing the gnarliest trails here in the North Shore. Best of luck!

Thanks for answering my question! I'll probably stick with middle of the road headsets since I don't ride super hard and would rather spend that extra money on something that I can feel when I'm riding.
So, you were serious asking about headset's bearings?!..
Henry mentioned the bearing tolerance difference between a cheap vs an expensive headset which is a factor. However an even more important and often overlooked factor when it comes to bearing performance is material grade and quality.
Good quality precision bearings basically require the Rolls Royce of high grade / high purity "Bearing" steels which are made from raw ore and alloying elements with very few inclusions or impurities. Whereas cheap bearings are often made with shitty recycled steel that can have any number of random impurities.
To give a real world analogy a ball rolling over an impurity near the surface of a bearing race is like a race car driving over a speed bump on an otherwise smooth racetrack. If you hit it in the right spot at the right speed or hit it too many times in the same spot it could cause a catastrophic failure.
In the world of bearings, MTB applications are very low speeds with low cycles so a middle of the road headset is probably a good bet for moderate use. They probably won't be using the purest steels in the bearings but it will still be exponentially better than a cheap low quality steel that may be used in low cost headsets.

I don't think you can just swap the bearing type, I think you need to swap the race/cup too.
Chances are that if the exposed bearings have gone bad, they will have damaged the cup they sit in to. So you will need to get the whole thing anyway.

I had the problem with my 150mm dropper being slightly too high on my large YT jeffsy and didn’t want to drop to a 125. It was aluminum so I used a pipe cutter and cut 25mm out of my seat tube if it’s bottoming out on the seat tube and it works perfect!
Won't work on this particular frame due to the insert design of the seat tube.
Did you double check for *clearance* (saddle-rear tire) when bottoming out your shock before cutting or did you just wing it?!
Just winged it and haven’t regretted it.
@@henry06x 😅👌🏻
170$ Headset can also double as a jewelry (but only if you have one of the 1% of top coolest girlfriends)🤩
OK 😂
Yeah but Chris king ones etc are very nice though the bearings so smooth.

#AskGMBNTech
Bike Geometry Question
Why are the GEO measurements not given with weight or SAG applied on the bike, be it full SUS or Hard Tail ?
For eg. wouldn't Stack height, BB height (or drop) or even chain stay length measurements be affected when recommended SAG is applied? Given different rear ends have different travel paths could applied SAG even change in the overall wheel base, especially with very slack head tubes with long travel forks and certain rear linkage?
Also as another eg. an aggressive HT with a 150-170mm fork, when 20 -30% sag is applied that can be up to almost 40mm less than its resting height won't that make the Stack height dramatically less and make the head tube angle steeper just by getting on it?
Thanks in advance.
#AskGMBNTech I tried to set-up my wheels tubeless and they leaked air from the join could this mean that my rims are damaged and if so do they need replacing? Also how do you increase small bump sensitivity on an air fork?
No you just likely have sleeved wheel. You need to tape it better.
Small bump sensitivity: assuming you don't have an upper level for the best solution is to upgrade the damper assembly. If you have a decent fork you might be able to adjust the damper settings and or change the shim stack in the damper. On a longer travel fork a volume spacer in the air spring may help.
Are they tubeless rated rims? Then they shouldn't leak => return them!
If not try using wider tubeless tape, reaching well into the grooves where the beads of the tire gonna sit.
Soldering (and sanding smooth!) the joint from the inside worked for me as well.
9:10 bike sizing is a important thing, having too short reach might result in arm pump, having too low cockpit, having brake levers at a steep angle, but with too short reach you can't have them flat, cus that would make it painful , at put wrist at an extreme angle.
So long enough reach, having brake levers flat, results in relaxed upper body and arms, it makes a huge difference I went from a way too short bike to a Geometron G1 Large, which fits me properly.
New bike is not always the right answer, but sometimes it actually is if it's a reach issue, you need a new frame.
also for hand pump, keep in mind if you use mechanical brakes the return spring might be so strong that it's heavier to press the lever, that's something I noticed, my fingers were fatiguing faster, I switched back to hydraulic, but then switched back to mechanical, but my fingers no longer were fatiguing, so that's due to my fingers being stronger probably due to a lot of more braking and working out.
Another thing to check is if you have issues with joint misalignment, this can cause movement restrictions, arm pump.
So if you have these issues and use too narrow handlebar your elbow , shoulder might pop easier, misalignment, but also if you ride very technical terrain and move a lot it can happen too, but with a too narrow handlebar it will happen very often.
These are issues I suffer from.
I also have very floppy wrists, which means it can pop up and down, and I can temporarily lose the power and full range of movement in the index finger, so I missed turns cus I could not brake properly.
but I have resolved this with wrist supports on both wrists, I use Troy Lee Designs WS 5205 Wrist Support.
It has reduced the play in the wrist, and has eliminated the braking problems.
of course there is still some slight misalignment but nothing major that hinders riding, so just easy pop to pop it back, but the issue I had before was so bad it could be felt, and heard sometimes.
But as mentioned in this video, you might have different problem, that might not be fixed with these methods and might be some internal problem in the arms.
I think that forearm workouts could help a lot if you are experiencing arm pump and you've already tried with different grip ticknesses and brake lever angles. I've found that calisthenics helps to solve a lot of riding issues.
#askgmbntech I have quite violent vibration through my fork lowers under progressive braking. Usually going downhill on roads/fireroads. The forks are 2015 Fox talas 110/140. If I tighten my headset anymore it effects my steering. Running slx front brake with a shimano 203 rotor. Should I be worried my forks are about to fall apart?
I used to have this issue on my last forks. It shouldn’t fall apart but still give them a call
Sounds like a warped front rotor and worn fork lower bushings.
Carbon bars over alloy will help with arm pump. The carbon absorbs a bit of the front end chatter. Nothing major but I does help. Curious if anyone knows how titanium bars do in this department?
I have a 2018 cannondale hardtail that I've been gradually upgrading (1-by conversion, dropper post, wide-range rear cassette), and next on my list is a fork. I currently have a decent 100mm straight-steerer coil and I'd like to slack it out with some more travel and upgrade to air, but all of the forks I have looked at have tapered steerers. The head tube has the shape and spacing for tapered forks, but the stock fork is a straight tube, and the stock headset is a 1 1/8 inch semi-integrated (I don't know the exact model but I will be checking on it soon). Will I need to buy something like the Cane Creek 40 EC44/40 Bottom Headset in order to run a tapered fork (or something else for that matter)? #AskGMBNTech
Is there any Problem with not extending the dropper post all the way?
On the arm pump, I'd suggest trying reduced high speed compression damping or getting a better fork that doesn't spike so much if this is the issue. Also Powerballs are good for hand strengthening.
#AskGMBNTech What colour is brake residue. (How can you tell what is oil/contaminants and what is brake residue)
To the dude with the Trek Fuel EX and stem length question, I have a 2016 Fuel EX 27.5 and found that the stem was too long and bar too narrow as well. I replaced the stem with a 42mm one and added 750mm bars. The handling was all over the place and the bike just didn't feel rigt, pretty shit to be completely honest. I've since bought a 55mm stem with 780mm bars and the bike feels and handles sooo much better. It's not an exact science and you'll just have to find what works for you unfortunately
#AskGMBNTech Do you guys know of any good quality discreet GPS tracking devices that I can mount somewhere on my bike? I just spent a big chunk of change on a custom Santa Cruz Bronson build and I'm a little bit paranoid since my last bike was stolen. I know some GARMIN trip computers have a tracking feature but a smart thief could recognize it, rip it off and discard it. Currently I have a Tile Sticker tracking device mounted but it only works if another tile user is nearby and does not have GPS functionality so I'm not sure how well it will work in rural areas.
comparing my bearings to them, mine was actually a bit expensive??
#AskGMBNTech . My nephew has a Raleigh Tokul 24. Comes with a Shimano Tourney 7spd derailleur.

Thankyou soo much for the reply Henry have some new pads on order going to fort William in 2 weeks if sturgeon lets us in so will have an experiment with brake / bar angles hope fully won’t come to seeing a doctor but we will have to see 😂

Whats a average price getting suspension frame bearings changed? Local workshop to me wanted £130. Seems steep to me
depends on frame, some bearing kits can be up to £70, then factor in labour costs, changing linkage bearing can be a fairly long process.
Sealed vs open?
#AskGMBNTech I've been a paintball player for the better part of two decades, as a result, I have heaps of DOW33 grease.

hi,
i have a 2015 cube stereo 140 with 2015 140mm fox 32, the air cap on the top has a plastic tube on the bottom of the cap which means i cant fit volume spacers and i would like to. i believe the only option to be to get a new, 2020 top aircap. what are your thoughts on this and any other suggestions. thanks!
@Jakub Augustynowicz try removing some of the stufing in the saddle to bring you back down to 10-20mm, or look at the nukeproof saddle the dh one not much padding in it and kinda hard but should work for you cost about 25 uk pounds
or he could actually order a new one and bodge his current one while waiting by limiting the stroke with a shoelace tied from the saddle rails to the seat tube.

#AskGMBNTech I have a 6 month old Canyon Strive and then I'm putting pressure on the pedals there is a cracking sound coming from either the bottom bracket area or the rear wheel area. Also when im putting my front wheel against a wall and but pressure on the pedals the bottom bracket flexes like 5mm to one side. Is this flex normal and did i just get unlucky with the bottom bracket or could the cause for this be a crack in my frame.
Well probably the bottom bracket which is easy to change or if you're really unlucky the bottom bracket shell is out of spec ( crappy tollerence, hole Misaligned or the hole are not quite round) and if the shell is out of spec you're only solution is a warranty claim .
For the bottom bracket to flex like that is not normal at all. Either the bb is broken or not seated properly or it is a frame issue as mentioned.

how many ball bearing should i used in a traditional headset that has 25.4mm fork diameter? Is it 20pcs or 16pcs ball bearing? #AskGMBNTech
#AskGMBNTech: Hi thank you guys for this show. We gotta know a lot of things from this. Good luck. By the way, I have a bike with a 3X chainring (saiguan 42T) and 7X Cassette (suangin TZ). The problem is when I put the chain to the largest chainring and the smallest cassette, it starts to slip ( no impact on other gears). So, can you please give advice on this problem
It's called cross chaining and you shouldn't do it.
@@doncrescas Dude said largest chainring + smallest sprocket = no cross chaining here!
Where is it slipping - in the front or the rear?!
Check for worn drivetrain. _(cassette and/or chain)_
Maybe try re-adjusting your b-tension screw (get the upper jockey wheel closer to the cassette) as well.
After that LBS/new parts.
@@geemail369 yes I seem to have misunderstood him. If he meant slipping off the cassette it could be the limit screw
@@doncrescas Yea, he's also talking the chain slipping without "affecting the other gears". I wonder ... 🙃
#askGMBNTech I’ve recently got a Cube Stereo 120. The 30t chainring is too small. I’d like to change it to a 34t. Should I change the chain as well?
You'll probably need to as you won't have enough links in the chain :-)

#AskGMBNTech Hi Doddy or Henry! Can Bottoming out Suspension Forks damage it and on what part does it bottom out. Thanks guys!
They are designed to bottom out sometimes so no but yes if you have way too little pressure! Usualla suspensions have rubber bump stops that take the hit if you bottom out so metal doesn't hit metal because then something could break

ive taken my wheelset to two different bikeshops for trueing and both have told me "we can try but we reccomend you replace your rims/wheelset"
second bikeshop did do a good job with the trueing bit it seems my wheels have some stupid problem as they are struggling to retain spoke tension (current riding is basically just dirt roads with maybe one rocky section where the biggest rock is about the sise of the average human foot)
so 3 rides in and the spokes are becoming spaghetti again (REEEEEEEEE)

#AskGMBNtechI have recently started mountain biking and my hands slip around on the grips (I have tried different gloves) as well as the grips being too thin. Could you recommend some grips please?
Slipping in general or due to sweat?!

#askGMBNTech What are the differences between changing the stem angle and changing the number of spacers on the headset, in order to change the height of handlebars? Would the two options perform/feel different?
Assuming the distance from the handlebars to the stearer tube were the same it won't matter. However the short stems that are now common tend to have no rise. The other option is to get handlebars with more rise.
Cool

hi there @GMBN TECH i have a request if i may, i am looking to build up an alloy frame muddy fox storm and was wondering if Doddy or any of the guys may have some old spares they may be willing to donate.
i am running a 26" wheel at the minute with a 21 speed set up and disk brakes, tho would like to change the crank set to give me a bit more ground clearance as i like to go through dirt tracks with some high stumps.
my main issue is the shocks, as the front forks are really bad for bottoming out and the way they spring back is brutal.
the rear shock is a standard 750LBS IN and it is a bit too solid for my weight as im only 9 stone, trust me it does not make for a comfortable ride.
i could probably change the saddle to help with the comfort but would need to take a look through your review videos for some tips when picking the right one for me.
any assistance that can be offered will be greatly appreciated and i would be more than happy to send pics and or video of the work being complete and some time spent in the dirt tracks here in glasgow scotland.
@ Hi, love the content, been trying to get in since months. I am in market for a new bike. The bikes in my budget are all hardtails. the 2 bikes I have shortlisted to.

#askgmbntech I have had a nightmare of a time keeping derailleurs going for more than a few rides. NX, GX, XO1, Shimano, it doesn't matter; they always blow out or bend or pop out from under me. Riding with some very good people I have been told my shifting technique is spot on. At 220lbs, am I just too heavy of a person for aggressive riding? This has caused me to look into gearboxes. A common complaint with them is drag/friction. Has anyone tried isotropic finishes on the gears to reduce this? Looking for a good fix to stay on the trails!

Can i do enduro with 130mm?
Yes and you’ll have a ton of fun! But you probably won’t be winning any races. I’d say 130-150 for fun-focused jovial riding and 160-180 if you’re looking for a serious speed sled to just barrel through the features. Go for the former if you climb most of what you ride and go for the latter if you shuttle/chairlift and/or plan to race at all. I’m on 145 rear, 150mm front and find it’s more than capable of crushing the gnarliest trails here in the North Shore. Best of luck!
