QXL Rings

Increased Ovalization for Experienced Q-Ring Users

The new ROTOR QXL is a Q-Ring with increased ovalization. They have a similar shape to standard Q-Rings, ensuring exceptional drivetrain stability. QXL rings do not replace standard Q-Rings, 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 delivery and consistent maximum (peak) effort, like time trials, sprints, breakaways, etc.

Why Q-Rings?

Q-Rings boost your performance by varying drivetrain resistance during pedaling in line with your legs natural strengths and weakness. They make better use of the strongest muscle groups (increasing positive work) and compensate for the weaker zones in the pedaling stroke (reducing negative work).
