Tankman Posted July 11, 2012 Share Is that a Q ring he used in front? Nope, those are O.Symetric Harmonic chainrings They have been around for a while: "O.Symetric Harmonic rings were tested independently in 1993, a 16km road test suggested they increased power by 33 watts and 1.5kph; a saving of 45 seconds in total. Rotor Q-Rings, a newer product, were tested more recently by Spain’s Universidad de Valladolid. Their study from 2006, conducted on elite U23 cyclists, compared sprint power, sustained power output and subsequent blood lactate response versus standard chainrings. The Q-Rings proved superior in every test, delivering a 12 watt gain in sustained power, 30 watts in sprint power and a nine percent reduction in blood lactate concentration."
