I have a 1995 Cannondale M500 that seems to be creaking down near the crank. I was going to look into taking it apart but my buddy who has the exact same "horse" said a bike shop told him you cannot service the cranks on this model. Something about them being "glued" in to the bottom bracket. Is this nonsense? (I've never done any work in this area so l cant tell by just looking at it)
TIA
