The Scoop

The new ROTOR QXL chainrings are Q-Rings with increased ovalization. They have a similar shape to standard Q-Rings, offering great drivetrain stability. QXL rings do not replace standard Q-Rings, but rather complement them as each is optimized for different rider profiles and situations.

QXL chainrings are most noticeable when riding in conditions of high power and consistent maximum effort, such as sprints, time trials, breakaways, etc.

Q-Rings boost performance by varying drivetrain resistance during pedaling sync with your legs’ natural strengths and weakness. They improve upon use of the strongest muscle groups and compensate for the weaker zones in the pedaling stroke.

Key QXL Ring features:
16% Ovalization (compared with 10% on regular Q-rings)
53t: Goes up to a 57t, down to a 49t
Geared for powerful (or higher power output) rider/racer
