The bearing , Chorus has been in there a few years now - recently while in the saddle & going up slight incline on small CR and maybe a couple down from the large on the rear cluster I get a sound that sounds like grinding coffee slowly with a manual grinder - it's not a metallic grinding sound & that's the best I can do describing it .
Could that be the type of sound you'd get when the bearing is wearing out - BTW the cranks are tight both sides and it's not chain rub and the sound seems to be coming from the BB area .
Thanks in advance to those who respond .
