Features

“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.

Q-Rings can increase an avid cyclist’s performance by as much as 4 seconds per km in a sprint – that’s twice the benefit of an aero wheelset!

Professionally, athletes who have chosen to ride them have put to rest any doubts about their performance by winning two grand tours, more than 25 Ironman races and over 20 UCI elite Road, MTB and CX world champion titles.
