Our Oval design has 3 main benefits; traction, traction and more traction. Forget any of the power gain claims that you've heard from the road side of the sport. For mountain, oval rings provide a more constant torque to the rear wheel thereby reducing spinouts and stalls on tough climbs.
*Shims - Included with rings. For 2x crank conversions; shims between the crank and ring get you back to an ideal 49-50mm chainline. For 3x crank conversions; shims under the bolt heads allow reuse of your 3x hardware.

If your Shimano 3x crank has a 30T middle ring this is the 1x ring you need. Shimano crank part numbers are usually laser etched on the pedal end of the crank on the back face.
