The rings are slightly oval and is supposed to optimize pedalling by improving or increasin the torque. The pedals are least efficient at 12/6 oclock and most efficient at 3/9. My question for the netters is, are they any good? While the best bike is a battle for small gains, 100 gms here 200 there, would this slight or major advantage be offset by some other problem, funny rhythm etc... If somebody has seen something published, i would be interested.. -- ~~ Mike Upmalis (mupmalis@watarts)
