Help with Drivetrain Sound(3 posts)

Help with Drivetrain SoundFred2000
Jul 9, 2002 1:34 PM
I am getting a creak from my drivetrain and I wanted to know if anyone has a good way of tracking sounds down, like a check list of the most likely sources and how to fix.

I have tightened my cleats (Looks) and the sounds seems pressure insensitive (There when I spin lightly and when I stomp - no change). It is only when the drivetrain is turning and in rhythm with my cadence. The rear wheel was trued and tightened two days ago by my LBS. I cleaned the drivetrain last night and the sound persisted.

Any thoughts would be great. Thanks, Jon

Seriously, you'd be surprised at some fo the causes of pedal rpm related noise:

Bottom bracket
flexy skewers
seat post

You need to rule things out one by one. It can be a bit frustrating, but you need to be persistent. My vote is for either the seatpost or the handlebar stem combo.
