Hi guys,
Please can anyone tell me if the shimano BB71 and BB91 are compatible. I've just bought BB71 as a replacement for my 2010 Zesty, but the original one (which has lasted nearly 18 months, seems almost unheard of)states it is a BB91. Are these the same size or have I bought the wrong thing? Not sure if the are just different levels of kit (like SLX compared to XT) or different sizes.
Any help greatly appreciated,
Tom

91 refers to the width I believe, so 71 isn't going to fit I wouldn't have thought.
