maybe? just mine?
I finally got my ultegra octalink cranks fixed up to my Dura-Ace BB, and well, it works pretty well- unless i'm going slow. in which case, my left crank arm moves independantly of the BB (and other crank arm, and chain). It's pretty annoying. Am i doing something wrong? Is this a common issue? I'm clearly an idiot for buying the hi-end, yet strangly cheep everywhere cranks. Guh.
