  1. can anyone tell me if the "SHIMANO UN52 (LX) BB" at the bottom of this website will fit my "Giant Boudler" Bike. The currnet one creaks really bad under pedel pressure and i want to replace it to hopefully stop that.

    Try greasing the threads on the one you got before throwing money away.You need english thread with either 68 or 73 shell width.You need to measure spindle length and match that.

    ah right ok, cheers mate, so it could be just the threads that are causing the creaking rather than the bearings, ill try that 1st :-) thanks for the info
