Okay. So I'm in the process of converting my U08 into a fixed gear town bike and the bottom bracket thing is killing me. Does anyone know what size spindle will fit into the cups on the bb so I can run a different crankset. My cranks still spin smooth and true and have almost no play, but I'm leery to take the cotter pins out and disect the thing if I won't be able to get it back together properly or if it won't do any good.

Any suggestions?
