Rotor rings are available in standard round versions (NoQ) and also elliptical Q-Ring Versions.
Q-Rings - Optimize your pedalling
The muscles recruited during pedalling, their relative strength during pedalling and the torque produced as a crankset rotates are shown in the figures below. From these graphs, it is clear that a round chainrings’ constant level of resistance interferes with optimal pedalling dynamics.
A Q-Ring gives a silky-smooth “perfect spin” by smoothening out torque variations and making better use of your strongest muscles.
What does this mean when you’re riding? You will discover increased endurance, realize explosive sprints and see a newfound tenacity in climbs. You will find that you can stick with the hardcore group that usually drops you. You will become an improved version of yourself, ready to set new PR’s and discover a new depth of performance. Triathletes will notice reduced strain in the bike split and better run split performance.
