Folks, I need some help.
Ive a weekend away biking this Friday and I cant get to a bike shop because work.
new wheels (Hope), new cassette, new chain, new gear cable. . On a 2016 whyte g160. Sram derail and single front.
Had put the cassette and chain on, then gave it to a shop to change cable and index / make sure all good.
However, after some light trails its started making noise, whenever theres any pressure on the downward stroke the rear end bakes a grunty drrrrrr drrrrrr noise, only on the power stroke. Freewheeling no noise. BB seems to be fine, but not had it out.
I cant see anything loose but its tricky to do as I cant replicate it on the stand. Somethings wrong though, suggestions on where to look?
remove rear caliper from the mounts and cable tie out of the way for a test... could be disc/caliper rubbing ?
Do you have another wheel to try ?
Tyre too wide and rubbing under power from frame flex?
brake/gear cable catching the tyre when suss compresses?
brake/gear cable catching the tyre when suss compresses?
That would be my guess.
Tom Howard likely has it.
I didnt even think about it being a rubbing noise. I will check.
Bikes is internally routed but ill see if something moved slightly. Tyre pressure? making it fat when under load?
It did sound more mechanical that rubbing but i would be very happy to proven wrong there.
Another mate said hope wheel stock bearing can be rubbish and to check them too. but freewheeling its fine or along a flat under not much load.
Will report back.
Pro 4 bearings are much improved over the older Pro 2’s that could be iffy at times. Is it an XD cassette? If so, did you remove the endcap from the hub before attempting to use the lockrring tool? If not, your cassette might not be fully engaged. That can give similar results. It’s a pain remembering to fit the cassette without the endcap and then fitting the endcap with the cassette in place but it needs to be done that way to get the tool to fully engage the splines.
Phone ringing in your back pocket? 😉
B screw on the derailleur not adjusted correctly allowing the top jockey wheel to ride on the cassette?
worth checking the rear wheel is properly seated in the dropouts.
You absolutely sure it's the rear end? You've changed the chain and the cassette, if the chainring is worn, that could be picking up on the new chain, especially under pedalling pressure.
Is your name femke van den driessche?
Chain correctly routed through derailleur?
It’s the chain on the 1x chainring
change the chainring and it will stop
Playing card in your spokes?
It’s the chain on the 1x chainring
change the chainring and it will stop
I've got a bit of a noise currently and i'm going to swap to a non N/W chainring this weekend for a test ride. I'm hoping the clutch mech on the rear will do enough of a job on it's own.
Spokey dokey?
