Rotor Shimano 4 Bolt Q rings Dura-Ace R9100 50/34t

With an oval shape for greater pedalling efficiency, Rotor’s 50/34t 4 Bolt Q Rings are compatible with Shimano’s 110 BCD Dura-Ace R9100 and Ultegra R8000 groupsets as well as many of Rotor’s own offerings. The shape reduces the resistance through the weaker part of the stroke and increases it during the stronger phase, resulting in a more even power output and less fatigue on the muscles. Ramps and pins ensure that shifts are fast and accurate, even under full power.
