I finished a short 150 mile ride today and about a mile from my house I heard and felt a click through the grips. I immediately slowed down to about 15mph and tried to listen closely and at random intervals between 5 and 30 seconds I'd hear a crunch, or several clicks and crunches, basically a really short clatter, and feel them too - all through my hands. I'm guessing bearings, but was wondering if anyone knew of anything else it could be? From the sound, I would think possibly transmission, but I'd expect to feel that in my butt and legs - not my hands....
Thanks!
