Who doesn’t want to finish a 1km sprint 1.6 seconds faster?
A 2011 study published in the International Journal of Sports Science and Engineering by independent California Polytechnic State University masters candidate, Christie O’Hara (who has since joined ROTOR’s competition and scientific staff) found statistically significant performance gains with Q-Rings.
This “end-of-ride” 1km time trial study complements ROTOR’s previous research, showing that participants experienced reduced oxygen consumption and heart rate with a corresponding increase in both power (26.7w) and speed (0.7 kph). Interestingly, the clear performance boost that Q-Rings claim was present even before some slow-to-adapt participants felt fully comfortable riding with 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 Q-Rings they performed better than with a normal, round chainring,” O’Hara said. “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 demonstrating the benefits of Q-Ring’s state that:
- All Q-Ring TT’s were faster, with an average gain of 1.6 seconds and 0.7 km/h (1.8%).
- All Q-Ring TT’s generated more power, with an average increase of 26.7w (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-Rings
