Re: I have a question regarding my bottom bracket

You will need a crank 9/8 speed compatible, 9 speed Shifter, 9 speed chain, and rear derailuer.
There is no BB32 Bottom Bracket on the market so your not looking at something right. If your bike has 7 speed stock it is going to be a basic bike with a thread in bottom bracket so if you go with the s600 crank you will also need a matching bottom bracket with the correct spindle length or if you have a square taper bottom bracket now they make a s600 crank that would work.
