Truvativ GXP crankset: mystery squeeking noise
I have a road bike setup with a Truvativ Rouleur compact crankset, with external GXP bearings.
It works great, but it has a mysterious squeaking noise. The noise goes on and off randomly; it will disappear for miles, suddenly start squeaking for miles, get quieter, get louder, then go off again. Sometimes it lasts less than a mile.
It's not a metallic squeak either. More plasticky or nylon-y. It sounds like something rubbing on nylon, possibly one of the outer seals.
Anyone have a similar issue with these and made it go away?
