Noisy Trek Rail, Rear end rumble diagnose & fix

[@matt45540]

Not a single bike mechanic in the US has offered to service my hub, I first brought it in at 600 mi. I can't really find a shop to rehub a wheel they all want me to buy a new one. You're clearly a master mechanic!

[@TheYorkshireBikeMechanic]

Thank you

[@YorkshireEmtb]

It amazes me how people can spend thousands on a bike , claim to be a mtb'er...and not know basic bike maintenance.....I mean it still has a dork disk on....love your video as always.

Nailed on observation

[@TheYorkshireBikeMechanic]

well spotted, nor for long

[@jamjar1106]

I would hardly suggest being able to diagnose, then the replace a front ring, free hub, cassette and chain as being 'basic bike maintenance'. What does it matter what people refer to themselves as anyway... I don't think we need snobbery within the enjoyment of riding your own bike how you want to ride is as an individual.

just installed a new bosch motor in my 21 trek rail 9.9 yesterday after 1700 miles she needed a refresh.

Ey where buy the motor ? Thanks!

I love that most of your business and videos are Emtb’s, living in Canada we don’t have very good Emtb mechanics I have to learn from you!! Lol Thx Dave!!!

Hi Steve, Im pleased you found my videos useful, any questions just ask, or if you get stuck Im happy to fly out to visit you, as long as you pay for the travel, lol.

Another great episode Dave 😁

[@TheYorkshireBikeMechanic]

Thanks Gary

[@steriospeaker]

Awesome video. I love watching these. Have you done a video on what routine maintenance I could/ should be doing on my own mtb? I’m never quite sure - what to wash, what to lube, when to change bearings, what lube to use……. Etc….. Thanks 👌🏻👍🏻🥇⭐️🤙🏻👊🏻

[@TheYorkshireBikeMechanic]

Hi Dave, Will see what I can do

[@mfren6253]

Dave’s videos shows the importance of regular maintenance and proper installation. I replace the consumables when needed but the hubs, even Bontrager hubs, should last a few thousand kms/miles with occasional maintenance. I think my Bontrager hub has 10k+ kms without an issue. I kinda wish it would fail so I can upgrade to i9’s hydra 32 spoke. Maybe if I stop maintaining the hubs. 🤔

[@TheYorkshireBikeMechanic]

Hi, Yes that will defiantly work, lol

[@justing6614]

Love ur videos

[@TheYorkshireBikeMechanic]

Thank you

[@matt45540]

Would always be nice to know how many miles these have. I'm at 1600 and mine starting to sound pretty rough, I at least wore out my stock tire 😂

[@gamz1]

Had a new rear wheel replaced under warranty on my trek 5, the hub lasted less than 350 miles so they gave me a new wheel.

[@TheYorkshireBikeMechanic]

Hi, That was the right thing to do if its in warranty, always try trek first.

[@orangedog73]

Those Bontrager hubs are absolute bobbins. I swapped my Rail hubs for Pro 4s after about 300 miles, Trek did give me £150 against a warranty claim, but they still insist on putting crap parts on expensive bikes.

[@getstrongby4038]

It's quite annoying tbh Are the hope wheels a lit better?

[@orangedog73]

@@getstrongby4038 Yeah, bombproof and easy to maintain.

[@getstrongby4038]

@@orangedog73 good stuff, was it just the hope hubs or the whole wheel you switched?

[@orangedog73]

It was just the hubs, I changed the wheels on my Rail to Fortus 30s anyway and kept the Bontrager rims with Pro4 Hubs as spares.

[@getstrongby4038]

@@orangedog73 yeah I'm looking at the wheels too, but might have to just get the hubs as I've just got hope cranks and chainring lol

[@mtbboy1993]

The hope Pro 4 hub was a nice upgrade, much easier to work on. I confirm they will last for years if maintained.

[@TheYorkshireBikeMechanic]

Thanks for watching and your comments

[@Extremegaz25]

Howdo dave, it seems to me that trek bearings aren't that good, I own and use regularly my trek rail 7, I love it, i replaced all the bearings in the rear wheel/ free hub at 1000 mile and I've got 1500 on now with same cassette and front gear, just changed chain incase it snapped, I've got a slight annoying noise what's just developed and I think its bearings in the frame, you can hear it free wheeling and under load.

[@TheYorkshireBikeMechanic]

Hey up. Hope your ok, frame bearings take a lot of punishment, especially the two main pivots near the bottom bracket.

[@Extremegaz25]

@@TheYorkshireBikeMechanic cheers dave I'll give it a check before me next ride, I'll let you know!

[@J0nny61]

Dave, that was brilliant, I've never ever seen a 14 mm Allen Key, didn't realise they existed. Will my Hope Pro Hub 4's need any maintenance?

[@TheYorkshireBikeMechanic]

Jon, Yes it certainly will, its easy to do. its the freehub body that will need more maintenance.

[@mtbboy1993]

the rotor does not sound too bad, I usually put mine up in a truing stand and true the rotor, I have the Parktool rotor add on. but new rotor for every ride would be crazy. I somehow manage to bend a rotor quite often. I have 223mm Trickstuff Dähle now, I've experienced a squeak with them, instead of a tick tick. I've not experienced that before. I was used to the rick tick of Hope rotors. I will probably bend all rotors. not sure what is causing it. But in some rides it can be sticks or something getting in there. But I've always experienced a bit of rotor warping.

you cannot see the gap in second video because of the angle of the camera, so did u check ur video befor posting it

Received my Trek rail like this from brand new. Took it back to the stealer and it’s still no good. Are the hubs an issue?

My Boost 148 free hub (Trek Powerfly 4) has the same problem with *ONLY 151 miles* on the clock !!!

[@timgearing5121]

Hi Dave, did you end up replacing the disc rotor? Cheers.

[@timgearing5121]

It’s 7am where I am in sunny QLD. Have a good night 😁

[@TheYorkshireBikeMechanic]

Yes I did, put a new 180mm on

[@GNX157]

How long does that 14mm Allen key need to be to reach the freehub to loosen it? Also, Does it need to be the bare key like you used or would a stub Allen key as part of a 1/2 socket and extension work?

[@TheYorkshireBikeMechanic]

Hi, it needs to be a bare key, you will find 14mm keys are a set length

[@GNX157]

@@TheYorkshireBikeMechanic I’m looking at tool hex socket extended length that’s 7 inches over all and the hex beam about 6. Would that work? GEARWRENCH 1/2" Drive Long Length Hex Bit Socket, 14mm - 82583

Shouldn't this be covered under warranty with it being its first service?

Hi, Thanks for watching and your comments, the customer could have taken this back to the shop he bought it from but chose not to.

Hi, The main thing to think about is reaching the 14mm screw from the opposite side, will it fit through the bearing housing.

@@TheYorkshireBikeMechanic cheers, just had a look at their website, they look great and not as expensive as I thought they might be.

[@GNX157]

Just a suggestion for learning purposes when doing multiple noises, my first thought was okay you identified the rotor, why not remove the caliper and isolate for the next noise.

[@TheYorkshireBikeMechanic]

Hi, fair point, will do next time

[@GNX157]

Actually now after watching the whole video, that brake rotor is probably not as bent as originally seemed. I think it’s got displacement issues because of the bad bearings, like the chain and cassette do.

[@TheYorkshireBikeMechanic]

Hi, Good comment

[@UKCRM]

Love the video and the explanation but my teeth itch at you not binning the dork disc while you had the cassette off!

[@TheYorkshireBikeMechanic]

donr worry it soon came off when we stripped the wheel down and built a new one

[@islandaerial3414]

That Bontrager hub is totally different than the one I have in my Powerfly 7. And, it appears to be just as poorly designed

[@TheYorkshireBikeMechanic]

Hi, Thanks for watching and your comments, we need more re-designed hubs for ebikes

[@SpringsMTBsac]

My Rail 5 hub bearings have just started to rumble, that's after about 18 months and 4000 miles. The original wheels that were fitted from new, barely lasted 400 miles. The dealership was very erratic service wise. They twice bodged the wheel, then finally sorted it under warranty. The original wheels were cup and cone which literally fell to bits. The replacements were sealed bearing. When you pay £4900 for a bike, you expect it to be decent quality from the get go. It seems a lot of rails have failures due to poor build, poor quality control and cheap components. I've got mine just about sussed now, after a lot of toil, time and expense. I wouldn't touch another new trek bike, with a big pole ! If you're thinking of buying one, look for a 2nd hand one that's had the snags sorted, the crappy components and tyres replaced. Actually, just avoid trek and buy a cube!🤔😄
