I decided to bump this older thread rather than starting a new one. I did a search on google for a track crankset that accepts a 110mm bottom bracket. I currently have an IRO 110mm bottom bracket used with the IRO track crankset, but I was looking for alternatives because I want a black one. I have found (http://www.universalcycles.com/shopp...s.php?id=16823) that the Pake crankset accepts either a 107mm bb or a 110mm bb - and this confuses me.....how can either work to create a desirable/straight chainline?
