QXL?s help you further improve your maximum sustainable output by offering a greater ovality, which increases drivetrain resistance during the most-productive part of your pedal rotation. If you ride for long sustained efforts at a high intensity, then orienting your QXL rings around your legs? natural strengths and weaknesses can make the difference between keeping pace with your rivals and putting them behind you.
QXL rings are Q-Rings with greater ovalization (16% vs. 10%) that were intended for existing Q-Ring users looking to capitalize on the performance benefits of oval rings. QXL¡¦s function the same as Q-Rings ¡X by maximizing the use of the most productive zones (increasing productive work) and minimizing the intensity of the weaker zones (decreasing negative work). Of course we would never discourage someone from reaching for QXL rings before Q-Rings, that choice depends on a variety of factors, including riding discipline, position, and bike setup. Q-Rings are ROTOR¡¦s flagship product, QXL rings were a natural progression from there.
