hey all, i just had a quick question about BB size for SS. i'm building up an old Specialized Hardrock into a SS machine. i have a UN52 BB that is 107 m in length. i put it in the bike and found that it is way to small. the chainrings and crank arms don't clear the chainstays. i was wondering if anyone has an info abotu what size is best to use to provide the proper clearance.
