New BB
I thinking of just updating to a cartridge style BB, but i'm a little confused. I currently have cup and loose ball style. Crank is older 600 w/bio-pace.
I know what all the mesurements mean. What I'm worried about is, are all the square tapers the same? It seems that shimano makes like 6 different sealed cart. style BB. How do you know whats works?
thanks

I suggest you visit Sheldon Browns site to get a grounding in Bottom Brackets.
Taking a semi-edjumicated stab at it, I'm gonna go with a 68mm square tapered, either 115 or 118mm in length. But I really don't know the speciifcs of the frame so threading and such is just a guess.
