I need to replace my crankset as two of the three chain rings are worn and its an old system.
I have a few questions however.
My bike currently has an 8 speed drivetrain, will a "9 speed" crankset work with the 8 speed system. I don't see why not as most of the movement is on the casset side and not up front, but I'm not sure.
Also, it is possible to replace "types" of BB's correct as long as they are the same size? My bike is old and currently has square taper, but most of the new systems use other BBs so I figured I'd replace it at the same time if possible.
Thanks in advance for any information.
