Using unique countersunk spacers and M5 Torx bolts OneUp has developed the only 30T oval ring that works with all 104BCD cranks.
OneUp's 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.
104 BCD Traction Chainring Specification
104 BCD Traction Chainring Installation: Align the small bump (small hole on direct mount rings) on the inner edge of the ring with your crank arm
