About 6 weeks ago it happened to me. It broke my derailleur. Lucky it only broke my cheap SRAM SX derailleur. Also lucky i was not far from my van. You make very informative content.
Great content. Thankfully I found your video before I had any damage. My rail had 11 miles on it after a ride in the woods and it came loose. I could move the Rear Derailleur by hand. I checked the product support page for the Trek Rail and sure enough the Derailleur Hanger should be Torqued to 25Nm. Great call and great catch!!! Trek should put out an advisory on the Trek product page as I'm sure this is happening to a whole lot of people!!!!
Hello All, quite a few rail owners have asked me if this is a defect or fault, no it's not. this is a serviceable part and as such like any other serviceable part on your bike it should be checked to make sure its bolted securely in place. During a normal service in my workshop any nut, bolt or fastener is checked for tightness. This hanger is designed to move backward on a heavy impact only. By making sure that it’s secure ant tight enough will stop it moving during normal use. If you don't feel confident in checking it or any other part of your rail your LBS will be glad to help i'm sure.
Seems like trek dose not wana own responsibility for a bad design.. like when I broke my 2nd F/S carbon top fuel. Trek would not talk to me but kept emailing bike shop I out lived my limited lifetime warranty.. even Giant bicycles replaced & upgraded my 3 cracked frames no questions asked, till I moved on to bigger enduro bikes
So let me get this straight. You’ve managed to crack/break not 1 but 5 different frames from different manufacturers? Where as most people will never have an issue with 1. I think the issue was intended use and probably not the bike. Like jumping 4 stories when a motorcycle with more suspension travel would be the better choice, or enduro bikes.
Nice one Dave. Not happened to me yet, but I do check my Rail bolts every month or so. They seem to be far worse than my Levo or any other bike I've had for working loose.
I bought rail 9 3 months ago, did around 400k I check everything every 100k seems everything still tightening up, but thank you for your help and I will make sure to check every while and then 👌🏻
Thank you so much for this information. Just this week I have bought a Trek rail 7 gen 3 and saw your video. Thought I'd just check it to see if it was loose . Not loose but more importantly not fully torqued up. I'll be checking this periodically. Thanks again.
Such a valuable contribution, thanks so much, it's not just that bike but any that use the same axle/hanger set up, I just pulled the axles out of my brand new Trek Roscoe (absolutely love this bike btw) to remove wheels to transport to a ride and found the hanger moving, thought it was weird and found your video, I removed the cap, cleaned it and refitted correctly with a little loctite so it won't unwind but is going to come apart ok later if needed, cheers from Australia for this excellent tip 👍
Hi, thanks for watching and your comments, Its a nice feeling when whatn you do people from as far away as Australia watch your stuff, im humbled, thank you
Beware I tightened this on a Trek Fuel EX8 2022, the same set up only last Saturday as part of my service checks and it snapped the nut well before 25nm which is a silly torque for a nylon nut to handle. Cycle shops I’ve spoke to informed me I’m not the first. I cringed as that torque wrench was getting near set. Has any one else snapped there’s ?
absolutely true. i also already snapped 2 of these on 2 bikes. they break so easily. i cant even reach 25nm this is why i torque em lower just not to snap them.
@@TheYorkshireBikeMechanic we've had it before and the tarmac melts, great for the fans but the racers are mad hot, I'll watch your vid properly now, on the motorbikes to day on a staycation my brother is over and were doing one day on EBIKE and next on motorcycle, yesterday we did 49 miles and 4000+ climbing and I still had 2 bars left, mostly in eco.
Hi Sean, Yes I have, any rail with the same hanger configuration is at risk unless its tightened up. It doesn't necessarily need to be as tight as the torque spec but tight enough not to move during normal use.
Can you get a metal replacement hanger? Just to ask you a question because you know all there is to know about Trek Rails. Trek rail 9.9 XO wireless 2020. Looking at buying a used one hardly used is this a good bike. Was there any frame or problems with this model. Cheers Trevor.
@@TheYorkshireBikeMechanic Great info and content. Mine was loose and when started torquing, the plastic hangar sheared. Only got up to 10Nm so must've been cracked. Do you know who makes the CNC replacements? The only one I could find was the Pilo Engineering Replacement. Thanks again.
Hi Dave another great video is right that the derailleur dose not swing back when you have made this adjustment.meaning should the derailleur still swing backwards on the bolt that fixes the derailleur to the hanger . Or should that be locked tight . Hope I have explained myself. Thanks Dave
Hi Barry, the derailleur should still swing back but the actual hanger should remain in the same place unless it's had an impact, in that case it may swing back. hope this helps.
Brilliant mechanical advice as usual Dave, you are the best! Thanks so much, I will check this on my rail if it ever arrives... Still waiting since October ordering and I am slowly going nuts (urgently need a torque wrench). How are the deliveries in the UK by the way? Here in Belgium it's pretty pathetic. My LBS (great shop nevertheless) keeps saying it will arrive very soon. The 2022 model has been advertised so I am not sure how I feel about waiting for last year's model...... Don't want to make myself unhappy but it's getting harder and harder..
@@TheYorkshireBikeMechanic finally called my LBS since the last announced ETA of theTrek Rail 9.8XT that I ordered last October and paid a 500€ deposit on, is a month overdue. Answer, sorry but you will have to wait until April next year (that's 18 months delivery time) for that bike! We are negotiating with Trek to provide an alternative. Are you kidding? I have seen that the price has inflated by 500€ since I ordered. My guess is that they are withholding to make me cancel my order and sell the bike instantly at the full price!!
Hi Dave, so I watched your TH-cam vid on checking your hanger tightness and decided to check my trek rail 7. Took my rear wheel off, Set my torque wrench to 25 NM and started to tighten, then boom! Rear hanger exploded and snapped off. Ok I thought, I have a spare hanger and bolt I’ll just change it. But the bolt will not unscrew from the frame, it looks like part of the plastic hanger is still attached and I can’t get it off. Any ideas?.
Hi Rachel, I’m sorry your hanger has broken off, more often than not it will need drilling out so that the bolt releases the broken hanger I’m afraid. It’s a fairly simple procedure if you are competent. You would expect that if a bolt is marked with a torque setting it should achieve that torque, can I ask, did you buy your bike from a high street retailer and collected it already built or was it an internet purchase delivered in a box
@@TheYorkshireBikeMechanic Hi Dave, the bike is about a year old now and I bought it from a dealer already built up. 25NM torque seems way too much for a plastic hanger to bolt to.
@@rachelrobinson4923 Hi Rachel, I agree 100% the bolt just needs to be tight enough to stop the hanger moving during normal use. I have added a warning description to the video. if your any where near Halifax Im happy to fix it for you free of charge.
@@TheYorkshireBikeMechanic hey thanks Dave, it’s not Rachel though it’s just her TH-cam account! I’m Peter her husband. We live in York so a bit of a drive to Halifax but if I can’t get it sorted locally I’ll take you up on that. Just thinking if this had happened out on the trail, despite having a spare hanger and bolt I wouldn’t have been able to fix it. Food for thought for Trek rail owners.
@@rachelrobinson4923 ok let me know if you need it repairing I’m happy to do it free of charge, I have hangers in stock too if you need to purchase one.
Does the thru axle attach into this bracket? Could tightening/removing the axle cause some of the looseness if the axle is overtightened? Thanks for the insight!
Hi, thanks for your comment, the axle does screw into the bracket but the bracket if correctly fitted will not move when fitting the axle but dont over tighten the axle.
Hi Trevor, here ya go www.chainreactioncycles.com/nukeproof-sram-udh-alloy-tough-hanger/rp-prod206071?gs=1&sku=sku837180&gclid=CjwKCAjwtcCVBhA0EiwAT1fY7_RKtsxL5tlA2w9anEyhFJd-Y0F4zQKHkSa2KBYhkXSXLTLveO-2DhoCrW8QAvD_BwE&gclsrc=aw.ds
aint wrong about the heat i went out on my e-bike and hit the trails to cool off seems trek have many issues with the rail e-bikes i have a haibike all mtn 3 and not had any issues at all so far
This happened on my 9.7 a couple months ago. Derailleur hit a large rock, going slow so not hard, hanger spun back, Derailleur scraped the paint off the ends of the chainstay and seatstay. After some struggle untangled the chain and got it rotated back down into place. Since I hadn't pedaled hard no other damage than paint. Tightened the hanger when I got home as it was pretty lose, but not to the torque spec as that just seemed too high. Bike shop should have tightened before sale!
Hi Royston, that true they don't. the other point which should be made is that if your torque wrench is old and has not been calibrated or tested care should be taken as false readings can be given, Thanks for watching and making a good point.
Same thing with Canyon spectral:on. Mine was loose and when I tightened it to 25nm I manages to strip the threads. It's secure with the wheel on but I suppose I'm better off with buying a new hanger.
Thanks for the info. I believe mine has moved but firm as the chain is currently too slack in the top gear. I’ve just been looking at Trek’s Quick Reference - Rail Alloy. It’s stating 15 Nm for the Derailleur Hanger.
@@TheYorkshireBikeMechanic thank you ive been looking for a good reversible toque wrench to do bb, cranks etc but hard to know if most of the ones you see do both ways.
Tungsten carbide cone head drill bit was bought to get it out after months meaning sram udh,so luckily didnt drill into frame or the blue bearing which i didnt know was there ,now 24.4 nm nip up set on wrench was what snapped it out,Now the next saga is putting the new udh in how much torque to st the udh at,i know its 25nm but ive seen so many people say 15 or 20 nm,any suggestions👍
@@TheYorkshireBikeMechanic im thinkin of selling it,250 miles on the clock,i wanted a scott patrion,its due to health i bought it dont need so called mountain bikers selling me a display bike and telling me after 6 hours sorry but we cant release the bike to you and they didnt say heres your money back ,they used to sell 10 or 20 grand racers a few years back,what does that tell you.anyhow daveill set it to 18 nm?cheers👍
Has anyone got any advice on how to remove it if it's snapped? There's almost no material left on the inside to grip with mole grips to allow me to slacken the Allen bolt. At a proper loss for how to get it out 😵💫
Hi Ryan, sorry your having trouble, The best way to get it out is the drill it out, it can be tricky, if you don't feel confident about doing it take it to your LBS
The SRAM UDH is a pig! Mine snapped way before 25 nm and I had to drill it out. Now my Axle is stuck in the replacement UDH-all the boltheads are stripped. Taking it to the shop tomorrow to drill it out
@@niccyhdb I had to take mine to the bike shop, they said they've had the issue a few times now and had to make a special tool to get it out. they said there is a tool you can buy but it costs a fortune.
Two year old vid.. i was doing bolt check. Snapped hanger with wheel in. Now nut stuck with some of the thread.. just spins. Got replacement cant remove it.. Not torn up frame teyin hack saw all sorts to it... What do i do? Trek rail 5
Hello the hanger broke , it Still seats on the thread inside... I cant loose it because i cant hold the other side its turning inside, how do i replace or even get him off?
@@TheYorkshireBikeMechanic did IT Yesterday, 1.5hour of hard work , but finally get it out. I saw a lot of people had problem with tightening... 25nm is a lit for plastic thread what do you think? I tightened it by a torque wrench but comments said , torque wrenches dont have moment at reverse tightening (left) , i hope you can understand me, sorry for poor english
Bugger tightened mine up and the plastic snapped off just past the thread, stuffed up the bolt as well getting it out- where the best place to get a hanger and the 8mm bolt part that screws into it.
Mine also snapped and we’re not alone, 25nm is a crazy setting for nylon, they used to be metal and I’m guessing it’s the same bolt used with the new nylon type hangar with 25nm labelled on when it’s half that in reality.
my brand new trek 9.7 nx rear udh has tore in half while tightening,i cant unscrew the end cap,the trek shop is 10 mile away,oh by yhe way it got tightened by 2 Halfords mechanics and trek mcr said it was released all perfect,most bolts even the front dbonair cap was loose and more,what should i do its floored me this,thnx dave
@@TheYorkshireBikeMechanic i just got a new replacement today off trek Piccadilly Manchester big help ,it was me tightened it up ,i set the torque wrench to 24 .4 nm as it was moving,its had its 1st aftersales check up as the hanger was loose and many other bolts from the day i bought it, but half of the udh end cap is still in the rear and it spins both ways so its a case of drillin the last endcap out like some people have done and its brittle carbon,thanks for gettin back so quick,thats quality aswell,anyhow dave toodle pip and see what happens next👍
Mine does not have a nut on It, the axle thru bolt screws in to the actual dropout hanger, when you remove the back wheel. The whole mech with hanger come of the frame. Is this wrong and should it have the nut on the hanger tightened to frame. Rockrider am 100s sram nx 11 spd
So what position is it supposed to be in? This just happened to me this weekend. only noticed it cause the rotor came loose andnhad to tighten it. turns out the whole back end was loose basically. 😮
Hi, thanks for watching. The idea of the UDH is that if your derailleur is knocked it will twist out of the way up towards the back wheel, so in its normal position it should be as far forward as it will go, the flat edge against the flat edge.
My Trek 9.7 came out of Trek Poole after a first service. Then a week later less than a mile into my ride in Wales changed up a gear on the trail, then BOOM the derailier went into the cassette and back wheel . It bent the chain as well. Had it repaired at a local bike shop who luckily had the spares at a cost £140.00. Loose Mech hanger. The Trek bike shop are basically not interested because i didn't take the bike back to them for repair. What else was i mean't to do? ruin my day and drive 3 hrs back to them.
Hi Adrian, Such a shame and what rubbish customer service, I really dont get why a main dealer should be so negative, you spent all that money, it would cost them hardly nothing to give you the money back that you spent, instead they have left you annoyed, my view is a customer is potentially for life. Thanks for your comments, you need to write a shitty letter to Trek.
@@TheYorkshireBikeMechanic So after a Email to Trek head office i have to contact the manager at Trek Poole to book my Rail in for a new XT derailier, and probably a chain ( Deore was fitted as a replacement) the supply of a spare hanger and a complimentary service when its next due. I guess i can't complain about that. Thanks for your reply.
I have a 2022 rail 5 and the rear hub bearing has worked lose. Lots of play. I took it to the local trek mechanic and he said that the bearing is not a sealed unit and thinks it’s not suitable for all the power going through it. I have asked him to upgrade it to what ever he thinks is best. There is a few owners who have reported the same problem
Hi, Thanks for watching and your comments. The industry is slowly realising that ebike rear hubs need to be designed for the ebike market, most hubs are normal bike hubs and struggle to cope with not only the power but accidental shifting under power. Good hubs come at a cost but they are well worth it in ebike applications, however maintenance is still key.
@@TheYorkshireBikeMechanic thanks for the reply.ive just came across your channel this morning and its great.hopfully get the bike back this weekend.ill post back to let you no the results
Oh crap, mine was loose, I set the torque wrench to 25nm started tightening and the plastic hanger snapped straight off! How can it be 25nm bolted into a plastic hanger?
Hy there. I wanna buy a spare hanger for my rail 7/2020....does anybody knows the spare part no.? I have searched for spare parts list, but I've got nothing yet. Thanks... from Europe.
@@TheYorkshireBikeMechanic well thanks for the videos! Drilling sounds really bad, ive put the bike to a trek dealer for warranty. Is this something u have had to deal with on a Trek? Im guessing its more to do with Trek design of that area rather than a Bontrager part fault. Feels like ive got the runt of the litter the power assistance output fluctuates twice a second as i view it on the display, apparently the speed sensor has an issue revealed by the dongle that plugs into computer. I moved the speed sensor slightly when ridewrapping it but thought input it back in pretty much same place 🙈
@@TheYorkshireBikeMechanic the bike was returned to Trek at i think Milton Keynes, they have said that the chainstay is cracked where the thru axle is. That explains allot. I did consider assisting the local to me Trek dealer in the task of drilling the thru axle out, so pretty glad i never. I guess it must of cracked when tightening the wheel on or cracked out on the trail. Warranty is key with carbon!
I noticed mine on my 9.8 was loose Torqued it to the left 25Nm and it destroyed the lip of the drop out and the plastic edge of the hanger at the same time… 😢
@@TheYorkshireBikeMechanic would love to know your opinion on turning a trek rail into a mullet. 29 front and 27.5 on the rear. Thinking of putting a 2.8 tyre on the back to try keep the geometry similar
@@ryanemtb4420 Hi Ryan, There are quite a few considerations to take into account, but in a nut shell a lot of downhill riders do it because is makes the front end slacker, also the 29 wheel will give better grip, on the downside you will lower your bottom bracket height, also the derailleur will be lower and you will get more pedal strikes, On the rail like most e-bikes the motor clearance isn't like a normal MTB it's much lower. The 2.8 tyre might be too close to your seat stays. Quite a few things to consider, but is you get get hold of a 27.5 rear wheel give it a try but be aware of the above info. On a last note, the rail is quite a capable bike and will do most things you need it to. My personal opinion, it's not for me. Dave
Hi, thanks for watching, it depends if checking pivot bolts and fastening for correct tightness is part on their pre delivery inspection procedure, it also depends on if you bought your bike over the internet and was delivered in a box.
Why isn’t it right in the first place ? ........isn’t there an inspection process to check things or are they built by incompetent people ? ....makes you wonder what else is wrong ....these are expensive bikes ...you would expect a quality build !
Hi, this is a very good question. If you buy your bike from a high street retailer already built up and you collect it from store then you should expect that it has been fully psi’s (pre delivery inspected) everything should be checked for tightness. If you buy online and have your bike delivered in a box, unless you have agreed with the place where you bought it from that they should pdi it it is up to you to make sure that a competent person will build up your bike and pdi it. It all still depend on your terms of sale and you should check this also.
@@TheYorkshireBikeMechanic well.......found it was loose, got torque wrench out set it to 19....(I never torque to full torque in one go.....) and crack....hanger sheered off. Hour later finally drilled fixing bolt from swing arm, and new hanger arriving tomorrow . So glad you made this video pal . Saved me a fortune
Hi, Thanks for watching, When fitted and tightened to the correct torque it works well but the torque seems a bit too high snapping the bolt sometimes.
I have same on my cube,checked it from new,lucky i did as it was over tightened as the collar snapped inside the nut,couldnt tell, Only found out when setting up from tubeless! Replaced it,and got a spare from when out,these plastic hangers are crap!
It’s designed to rotate on an impact protecting the derailleur itself. The one in the video is too loose, but it’s movement should be expected. www.sram.com/en/sram/models/ac-drhg-mtb-a1
Hi Austin, thanks for watching, it shouldn’t move at all during normal use when it’s correctly torqued up even by hand, unless under impact like you say, but this issue is where the retaining bolt is loose to begin with, some are more than loose, I’ve seen them when the hanger has sheared the plastic surround. You can’t believe how many are not torqued correctly causing massive damage.
We Rail owners really appreciate your help. Thank you so much

Hi Rachel, I’m sorry your hanger has broken off, more often than not it will need drilling out so that the bolt releases the broken hanger I’m afraid. It’s a fairly simple procedure if you are competent. You would expect that if a bolt is marked with a torque setting it should achieve that torque, can I ask, did you buy your bike from a high street retailer and collected it already built or was it an internet purchase delivered in a box
@@TheYorkshireBikeMechanic Hi Dave, the bike is about a year old now and I bought it from a dealer already built up. 25NM torque seems way too much for a plastic hanger to bolt to.
@@rachelrobinson4923 Hi Rachel, I agree 100% the bolt just needs to be tight enough to stop the hanger moving during normal use. I have added a warning description to the video. if your any where near Halifax Im happy to fix it for you free of charge.
@@TheYorkshireBikeMechanic hey thanks Dave, it’s not Rachel though it’s just her TH-cam account! I’m Peter her husband. We live in York so a bit of a drive to Halifax but if I can’t get it sorted locally I’ll take you up on that.
Just thinking if this had happened out on the trail, despite having a spare hanger and bolt I wouldn’t have been able to fix it. Food for thought for Trek rail owners.
@@rachelrobinson4923 ok let me know if you need it repairing I’m happy to do it free of charge, I have hangers in stock too if you need to purchase one.
Does the thru axle attach into this bracket? Could tightening/removing the axle cause some of the looseness if the axle is overtightened? Thanks for the insight!
Hi, thanks for your comment, the axle does screw into the bracket but the bracket if correctly fitted will not move when fitting the axle but dont over tighten the axle.
Yes ,and is that the reason it is leftthreded ?
I’ve got the Trek Rail 9 GX 2022 and mines well loose! Phew thanks for your help!
Glad I could help!
That is a bad design, oh gosh! Do you think it will loose if you remove the wheel? Great tip to check it!
Thanks for watching, it should stay in place once the wheel is removed.
Thank you for this excellent advise - I will check mine tomorrow
Hi, thanks for watching and your comment
great content, just bought me a used rail 5, have seen some videos where the battery jumps out, is this something I should be afraid of?
Hi, Thanks for watching, if the locking mechanism is working correctly and well maintained you should be ok but check it.
Do you have a link for a better derailleur hanger. It’s for a trek rail 9.8xt. Cheers Trevor.

aint wrong about the heat i went out on my e-bike and hit the trails to cool off seems trek have many issues with the rail e-bikes i have a haibike all mtn 3 and not had any issues at all so far
I'm new to tools and bikes 😅 l
Please could you tell me what tool you used to tighten that part of the bike. Thanks 😊
Hi, Thanks for watching and your comments, it's an 8mm hex key
This happened on my 9.7 a couple months ago. Derailleur hit a large rock, going slow so not hard, hanger spun back, Derailleur scraped the paint off the ends of the chainstay and seatstay. After some struggle untangled the chain and got it rotated back down into place. Since I hadn't pedaled hard no other damage than paint. Tightened the hanger when I got home as it was pretty lose, but not to the torque spec as that just seemed too high. Bike shop should have tightened before sale!
It does seem a rather high torque.
@@TheYorkshireBikeMechanic They definitely know it's a failure point with a torque spec that high.👍 they decided it's not going anywhere now 💪😎
cheers Dave, BTW not telling you how suck eggs, some torque wrenches dont work on lefthand threads, as I found out when tightening my Hanger bolt
Hi Royston, that true they don't. the other point which should be made is that if your torque wrench is old and has not been calibrated or tested care should be taken as false readings can be given, Thanks for watching and making a good point.
Great video. Can it be tightened with the wheel still on? Thanks
Hi thanks for watching, the wheel needs to be out first.
Same thing with Canyon spectral:on. Mine was loose and when I tightened it to 25nm I manages to strip the threads. It's secure with the wheel on but I suppose I'm better off with buying a new hanger.
Hi thanks for watching, yes defiantly get a new one.
hi dave ..are all the bolts on a trek rail anti clock wise
Hi Irene, No but the gear hanger locking nut is
Thanks for the info. I believe mine has moved but firm as the chain is currently too slack in the top gear. I’ve just been looking at Trek’s Quick Reference - Rail Alloy. It’s stating 15 Nm for the Derailleur Hanger.
Hi, yes torque settings have now been reduced especially for the ally ones, thanks for your comment
@@TheYorkshireBikeMechanic so is it 15Nm or 25Nm
Great job Dave! GOOD HEADS UP!!
Thank you
What torque wrench did you use in this video? Guessing it can torque cw and acw?
Hi, It's a Halfords professional 8 -60 nm, reversable
@@TheYorkshireBikeMechanic thank you ive been looking for a good reversible toque wrench to do bb, cranks etc but hard to know if most of the ones you see do both ways.

Tungsten carbide cone head drill bit was bought to get it out after months meaning sram udh,so luckily didnt drill into frame or the blue bearing which i didnt know was there ,now 24.4 nm nip up set on wrench was what snapped it out,Now the next saga is putting the new udh in how much torque to st the udh at,i know its 25nm but ive seen so many people say 15 or 20 nm,any suggestions👍

Has anyone got any advice on how to remove it if it's snapped? There's almost no material left on the inside to grip with mole grips to allow me to slacken the Allen bolt. At a proper loss for how to get it out 😵💫
Hi Ryan, sorry your having trouble, The best way to get it out is the drill it out, it can be tricky, if you don't feel confident about doing it take it to your LBS
@@TheYorkshireBikeMechanic yea mate I'm thinking that might have to be the road I go down. Only riden the bike for a week.
The SRAM UDH is a pig! Mine snapped way before 25 nm and I had to drill it out. Now my Axle is stuck in the replacement UDH-all the boltheads are stripped. Taking it to the shop tomorrow to drill it out
@@niccyhdb I had to take mine to the bike shop, they said they've had the issue a few times now and had to make a special tool to get it out. they said there is a tool you can buy but it costs a fortune.

@@TheYorkshireBikeMechanic did IT Yesterday, 1.5hour of hard work , but finally get it out. I saw a lot of people had problem with tightening... 25nm is a lit for plastic thread what do you think?

Glad you enjoyed it
Bugger tightened mine up and the plastic snapped off just past the thread, stuffed up the bolt as well getting it out- where the best place to get a hanger and the 8mm bolt part that screws into it.

@@TheYorkshireBikeMechanic yes have one on order
Mine also snapped and we’re not alone, 25nm is a crazy setting for nylon, they used to be metal and I’m guessing it’s the same bolt used with the new nylon type hangar with 25nm labelled on when it’s half that in reality.
my brand new trek 9.7 nx rear udh has tore in half while tightening,i cant unscrew the end cap,the trek shop is 10 mile away,oh by yhe way it got tightened by 2 Halfords mechanics and trek mcr said it was released all perfect,most bolts even the front dbonair cap was loose and more,what should i do its floored me this,thnx dave

Mine does not have a nut on It, the axle thru bolt screws in to the actual dropout hanger, when you remove the back wheel. The whole mech with hanger come of the frame. Is this wrong and should it have the nut on the hanger tightened to frame. Rockrider am 100s sram nx 11 spd
Hi Stuart, can you send me some photos, dave@cycle-fast.co.uk
You pay all that money for a bike and get these problems!
i thought they changed it
it easy to modify it so it is not possible to rotate !!
good one
Hi thanks for watching, I don’t know if any modification
So what position is it supposed to be in? This just happened to me this weekend. only noticed it cause the rotor came loose andnhad to tighten it. turns out the whole back end was loose basically. 😮
Hi, thanks for watching. The idea of the UDH is that if your derailleur is knocked it will twist out of the way up towards the back wheel, so in its normal position it should be as far forward as it will go, the flat edge against the flat edge.
@TheYorkshireBikeMechanic thanks! So basically all the way down? (Clockwise if your in that side)
Great tip! when I have a new bike I aways check all tork and this in particular was not so tigth (25N)
Glad it helped!
My Trek 9.7 came out of Trek Poole after a first service. Then a week later less than a mile into my ride in Wales changed up a gear on the trail, then BOOM the derailier went into the cassette and back wheel . It bent the chain as well. Had it repaired at a local bike shop who luckily had the spares at a cost £140.00. Loose Mech hanger. The Trek bike shop are basically not interested because i didn't take the bike back to them for repair. What else was i mean't to do? ruin my day and drive 3 hrs back to them.
Hi Adrian, Such a shame and what rubbish customer service, I really dont get why a main dealer should be so negative, you spent all that money, it would cost them hardly nothing to give you the money back that you spent, instead they have left you annoyed, my view is a customer is potentially for life. Thanks for your comments, you need to write a shitty letter to Trek.
@@TheYorkshireBikeMechanic So after a Email to Trek head office i have to contact the manager at Trek Poole to book my Rail in for a new XT derailier, and probably a chain ( Deore was fitted as a replacement) the supply of a spare hanger and a complimentary service when its next due. I guess i can't complain about that.
Thanks for your reply.
Anybody know if the trek slash is the same? Thanks
Why did you need to remove the wheel to do that mate?
It was easier to explain about other matters related to the rear wheel and its position
@@TheYorkshireBikeMechanic ahh I see, fair enough!
I actually snapped the hanger trying this, turns out my torque wrench doesn't work in reverse lol
I have a 2022 rail 5 and the rear hub bearing has worked lose. Lots of play. I took it to the local trek mechanic and he said that the bearing is not a sealed unit and thinks it’s not suitable for all the power going through it. I have asked him to upgrade it to what ever he thinks is best. There is a few owners who have reported the same problem
Hi, Thanks for watching and your comments. The industry is slowly realising that ebike rear hubs need to be designed for the ebike market, most hubs are normal bike hubs and struggle to cope with not only the power but accidental shifting under power. Good hubs come at a cost but they are well worth it in ebike applications, however maintenance is still key.
@@TheYorkshireBikeMechanic thanks for the reply.ive just came across your channel this morning and its great.hopfully get the bike back this weekend.ill post back to let you no the results
Thanks a lot, must check my remedy now.

Oh crap, mine was loose, I set the torque wrench to 25nm started tightening and the plastic hanger snapped straight off! How can it be 25nm bolted into a plastic hanger?

My rear thru axle on my trek Fuel Exe has seized and no amount of force is removing it, the bikes only 1 month old
Hi, thank you for watching and your comments, its a possible drilling job then im afraid
@@TheYorkshireBikeMechanic well thanks for the videos!
Drilling sounds really bad, ive put the bike to a trek dealer for warranty. Is this something u have had to deal with on a Trek? Im guessing its more to do with Trek design of that area rather than a Bontrager part fault. Feels like ive got the runt of the litter the power assistance output fluctuates twice a second as i view it on the display, apparently the speed sensor has an issue revealed by the dongle that plugs into computer. I moved the speed sensor slightly when ridewrapping it but thought input it back in pretty much same place 🙈
@@TheYorkshireBikeMechanic the bike was returned to Trek at i think Milton Keynes, they have said that the chainstay is cracked where the thru axle is. That explains allot. I did consider assisting the local to me Trek dealer in the task of drilling the thru axle out, so pretty glad i never. I guess it must of cracked when tightening the wheel on or cracked out on the trail. Warranty is key with carbon!
I noticed mine on my 9.8 was loose Torqued it to the left 25Nm and it destroyed the lip of the drop out and the plastic edge of the hanger at the same time… 😢
Great vid
Thanks Ryan
@@TheYorkshireBikeMechanic would love to know your opinion on turning a trek rail into a mullet. 29 front and 27.5 on the rear. Thinking of putting a 2.8 tyre on the back to try keep the geometry similar
@@ryanemtb4420 Hi Ryan, There are quite a few considerations to take into account, but in a nut shell a lot of downhill riders do it because is makes the front end slacker, also the 29 wheel will give better grip, on the downside you will lower your bottom bracket height, also the derailleur will be lower and you will get more pedal strikes, On the rail like most e-bikes the motor clearance isn't like a normal MTB it's much lower. The 2.8 tyre might be too close to your seat stays. Quite a few things to consider, but is you get get hold of a 27.5 rear wheel give it a try but be aware of the above info. On a last note, the rail is quite a capable bike and will do most things you need it to. My personal opinion, it's not for me. Dave
@@TheYorkshireBikeMechanic I appreciate the expert advice. Iv decided to stick with the 29
TY!

Thanks for watching and your comments, lol
Did I see a bent spoke??
Hi, yes you did
Surely the bike shop would tighten this
Hi, thanks for watching, it depends if checking pivot bolts and fastening for correct tightness is part on their pre delivery inspection procedure, it also depends on if you bought your bike over the internet and was delivered in a box.
Saaaayyyyy whaaaaaa?!
Why isn’t it right in the first place ? ........isn’t there an inspection process to check things or are they built by incompetent people ? ....makes you wonder what else is wrong ....these are expensive bikes ...you would expect a quality build !
Hi, this is a very good question. If you buy your bike from a high street retailer already built up and you collect it from store then you should expect that it has been fully psi’s (pre delivery inspected) everything should be checked for tightness. If you buy online and have your bike delivered in a box, unless you have agreed with the place where you bought it from that they should pdi it it is up to you to make sure that a competent person will build up your bike and pdi it. It all still depend on your terms of sale and you should check this also.
A couple of my riding mates have these treks and I'm really surprised how shit they are the build quality is really poor
Me ... rushes to shed to check rail so I don't damage the eagle axs
Hi, yes I think I would have done the same.

Isnt this just a bad engineering
Hi, Thanks for watching, When fitted and tightened to the correct torque it works well but the torque seems a bit too high snapping the bolt sometimes.
this would have saved my carbon chainstays..unfortunately trek said it was my fault and crash damage.. plenty of $$$$$

Replaced it,and got a spare from when out,these plastic hangers are crap!
Hi Pete, thanks for your comments
It’s designed to rotate on an impact protecting the derailleur itself. The one in the video is too loose, but it’s movement should be expected.
www.sram.com/en/sram/models/ac-drhg-mtb-a1
Hi Austin, thanks for watching, it shouldn’t move at all during normal use when it’s correctly torqued up even by hand, unless under impact like you say, but this issue is where the retaining bolt is loose to begin with, some are more than loose, I’ve seen them when the hanger has sheared the plastic surround. You can’t believe how many are not torqued correctly causing massive damage.
