Folks,
My bottom bracket (I believe) maybe on the way out (again). Sometimes it clicks with every one crank revolution (hence suspect bottom bracket), however at other times it does not . The BB is Shimano XT sealed. Any ideas on what may cause this perhaps a flattened bearing? Sometimes it can be soundless for days Other times it is loud and most annoying When it is making noise (not right now presently), the noise is amplified when peddling harder.
The BB was replaced only two years ago (I think, might be three cant rightly remember) and I only (now) use the bike for regular commuting .
Bike is Kona Caldera 1999 (with bits and bobs replaced and still going strong!).
