The Q-factor of 151mm stabilizes pedaling biomechanics, promoting comfort and efficiency during extended rides.

Style & Use Case

Finished in sleek black, the FC-RX610-1 combines style with functionality-perfect for gravel riders, adventure cyclists, and enthusiasts tackling mixed terrain. Its robust construction and innovative gearing make it ideal for gravel racing, bikepacking, endurance rides, and daily adventuring where dependability and performance are crucial.
