R rod998 Dirt Disciple Apr 13, 2009 #1 Just a quick question. Looking for the right bottom bracket for my Cannondale SM700 frame,as far as i can see from vintage cannondale the width is 68mm. What would be the best one though and correct length measurement for chainset-crank?

R rod998 Dirt Disciple Apr 13, 2009 #6 Im not sure what year the chainset is,early-mid 90's. The driveside has FC-M550 stamped into the back of it.

R rod998 Dirt Disciple Apr 13, 2009 #8 Thats great, thanks. Looking at the Shimano UN54, they do 68-122. Seems to be alright quality for the price...
