Which user profile for which Qring?

Our two Q-rings (standard and XL) are more efficient than a round chainring, but each is optimized for a specific type of user. To help customers choose the right product, we have created a ?Selection Guide? (CF Table) to allow customers to determine which version of Q-Rings is best suited to their riding style, type of effort. .

Standard Q-Rings are intended for runners with predominantly slow muscle contraction (Slow fibers). They seek flexibility and economy of their pedaling to express their potential. These runners are those with a medium to low peak power (endurance cyclists). In this case, less ovalization is preferable in order to maintain optimal muscle activation. Standard Q-Rings in particular improve constant-intensity effort while seated, over long distances, where economy is essential for performance.
