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.
- Get ultimate traction by smoothing out the torque you deliver to your rear tire
- 12% ovality (32T is equal to a 30T-34T range)
- 115° clocking from crank arm puts the major axis in your power stroke
- Subtly slotted bolt holes allow for a perfect fit with both 94 and 96 BCD symmetrical crank arms.
- Narrow Wide tooth profile eliminates chain drop with the perfect chain mesh fit.
- Perfect 49mm chainline with 2mm Shims included for a quieter drivetrain, improved chainring wear and best no drop performance.
- Reuse your existing 8-10mm long ring hardware. No new bolt packs required.
- Aggressive crud chamfers for awesome mud shedding performance and extended ring life.
- Reinforced wide tooth design provides maximum ring durability when run without a bash guard.
- Made from hard wearing 7075-T6 aluminum plate.
*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.
