Confused a little bit here. I got Shimano 600 (Ultegra 6400, came with biopace rings) crank set - http://www.velobase.com/ViewComponen...m=115&AbsPos=1. On the spindle and velobase it says 115mm but when I measure it end to end - it is more like 122mm. So when I go to my LBS tomorrow to buy sealed shimano BB - which one should I get, 115 or 122?
As it sits right now (on original spindle) - it gives me desired 52mm chain line on outer ring so would like to match it exactly.
