Rotor QX2 MTB oval chainring, 64 mm internal double chainring for Shimano XT M8000 crankset

The benefits of the oval chainring are now well established, whether on the road or on a mountain bike. This technology offers a significant increase in efficiency, as well as a reduction in lactic acid production. Pedalling is also smoother, and the top and bottom dead centres are passed through with ease.

Other benefits include a significant reduction in stress on the knee joints. Heart rate is also lower.

The Rotor QX2 in the outer position has a 64 mm bolt circle. It is only compatible with Shimano XT M8000 or SLX four-arm MTB cranksets.
