ROTOR QXL AERO 10/11 Speed Outer Chainring 130 mm

The new QXL are Q-Rings with increased ovalisation. They have the same form as the standard Q-Ring's, in order to maintain exceptionally fluid gear changing.

The QXL are designed for competitors with rapid muscle contractions (fast-twitch muscle fibres). These are generally competitors labelled, 'powerful,' with a muscle mass and power peak that is above the average (sprinters, for example). For such athletes, increased ovalisation allows them to reduce negative work, compared to standard ovalisation. The QXL is more efficient during intensive riding (sprinting and climbing) as it allows the optimisation of the power peak, while at the same time, dead points are decreased.
