OneUp your climbing performance and clean more climbs with our oval chainrings.

NEW - NOW AVAILABLE IN 30T - Using unique countersunk spacers and M5 Torx bolts OneUp has developed the only 30T oval ring that works with all 104BCD cranks.

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.

115° clocking from crank arm puts the major axis in your power stroke
