104 BCD Traction 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.

• 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
• Narrow Wide tooth profile eliminates chain drop with the perfect chain mesh fit
• Perfect chainline with built in offset. For a quieter drivetrain with improved chain wear and best drop performance
• Reuse your existing 8-10mm long ring hardware. No new bolt packs required, saves you £'s!
• 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
• Made from hard wearing 7075-T6 aluminum plate
• 32T rings have integrated shims and M8 chainring bolt threads
• 30T rings have integrated shims and M5 chainring bolt threads to allow the smallest ring size possible on a 104 BCD crank. Bolts and spacers included.
