The bike was originally sold with biopace crank rings; if you notice the crank rings are oval, not round. Theory was, oval saved your knees and carried momentum/power threw the deadspot in the cycle. The idea got trashed because spinners thought it was counterproductive, but the crank wasn't made for racers. I like them, on the inner rings particularly, but they are dissed by the wouldbe racer crowd. Enjoy.
