Rotor QXL chainrings

overviewThe new QXL is a Q-Ring with increased ovalization. They have a similar shape to standard QRings, 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.
We believe that standard Q-Rings offer an optimal adaptation-stability-biomechanical balance for most cyclists. However, we are aware of scientific research and feedback from pro riders that shows that greater ovality can be desirable and useful for certain athletes since not all riders have the same muscle build, riding form, or pedaling style. The QXL rings are designed more for a type of rider rather than a specific cycling discipline.
When we applied our biomechanical and engineering knowledge to an increased ovality, we found that the feedback was positive from many professional riders previously wary of Q-Rings. These athletes predominantly reported an improved cycling experience, particularly when pedaling out of the saddle and accelerating. We have seen that QXL chainrings are most noticeable when riding in conditions of high power delivery and consistent maximum (peak) effort, like time trials, sprints, breakaways, riding styles that involve frequent out of the saddle riding, etc.
Target customer profile: for riders looking for increased ovalization
“Powerful” riders with larger muscle mass that produce a higher peak and average power output typically prefer QXL rings. For example, sprinters tend to have predominantly fast twitch muscle build. This makes an increased degree of optimal ovality because these riders benefit from the decreased negative work offered by the enlarged ovality.
QXL rings noticeably improve out of the saddle riding (sprint or climb), helping most during moments of maximum effort when the “dead spots” become far more critical.
