I have a SRAM Force BB. I’ve noticed lot of creaking and awful noise especially up climbs and when torque is forcefully applied to the crank arms. I had no
idea. LBS said I might have corrosion in the frame. A riding buddy suggested I replace the BB.
How big a difference will a new BB make as in how many watts have I been losing? 5-10? As well, should I go with a $30 GXP or something better with ceramic bearings? Is there that big of a deal? I also heard the ones with ceramic bearings wear out in 6-12 months. Is that true?
