Before tearing things apart and figuring out the hard ways, hoping someone can short-cut me some info. Have a 2013 TT Tour 2 with Elite drive train (SRAM 9-gear cassette, etc.) with 3000 miles. I just recently gave it a thorough cleaning, discovered that chain was done so replaced it. During this, spinning the rear wheel by hand seems noisier and slows quicker than what I think to be normal. Wondering if there is wear/tear with the rear wheel bearing and/or the cleaning (Simple Green degreaser) might have gotten in the bearing.
I have OK general and bike mechanical abilities but haven't worked on cycle rear bearings. Are these sealed, or can they be cleaned, repacked, etc.? Advice on replacement or regreasing? Thanks.
(Prefer to do this stuff myself at least to become more self sufficient)
