Who doesn’t want to finish a 1km sprint 1.6 seconds faster?

ROTOR is excited to announce the publication of a new scientific study on its paradigm changing, performance boosting, oval chainrings.

The study was published in the International Journal of Sports Science and Engineering by an independent Cal Poly University graduate, Christie O’Hara (who has since joined ROTOR’s competition & scientific staff).

This “end-of-ride” 1km time trial study complements our previous research, showing that participants experienced reduced lactate and heart rate with a corresponding increase in both power (26.7w) and speed (0.7 kph). Interestingly, the clear performance boost Q-Rings give was present even before some slow to adapt participants felt fully comfortable riding them.

“The 1km time trials were done after 45 minutes of intermediate to hard effort riding, thereby simulating race like conditions. By the time the 1km TT came around, participants weren’t fresh, but after riding on the Q-Ring they performed better than with a normal round chainring,” said O’Hara, adding “Even though the results were recorded with elite athletes, I think the Q-Rings’ performance benefits would be even greater for beginner and intermediate athletes.”

The summarized results of this study, showing the Q-Ring’s clear benefits are:

  • All Q-ring TT’s were faster, with an average gain of 1.6 sec and 0.7 km/h (1.8%)
  • All Q-Ring TT’s generated more power, with average increase of 26.7 W (6.2%)
  • Reduced oxygen consumption and heart rate in submaximal tests
  • An immediate performance increase on switching from round rings to Q-Rings
  • An immediate performance reduction on switching back to round chainrings
  • It also appears that the more effort a cyclist exerts, the greater the benefit of Q’s
