Victories help quell doubts about elliptical chainrings
Any doubts in the professional ranks about Rotor’s elliptical Q-Rings seem to be quickly fading thanks to a string of top-level victories.
Carlos Sastre (CSC-Saxo Bank) used a pair to capture his first Tour de France in July, Marianne Vos was Q-equipped when she won the 2006 UCI cyclo-cross World Championship and now Daphny van den Brand has captured this year’s cyclo-cross World Cup opener in Kalmthout, Belgium.
Rotor claims its Q-Rings deliver a 4.1 percent power increase at a similar level of effort when compared with round rings, as well as a 9.1 percent decrease in lactic acid production and a two percent reduction in heart rate.
Whether or not these numbers pass muster in the real world is still debatable but the proliferation of non-round rings in the professional ranks is certainly one that we will continue to watch closely.
