Oval CX 110BCD 1x Chainring

What Our Gearhead® Experts Are Saying:

"I recommend this ring for riders converting older road cranks to 1x cyclocross or gravel. Retention is excellent without extra hardware, and the oval timing noticeably smooths power on technical climbs."

The CX 1X OVAL 110/5 BCD N/W Traction Chainring is engineered for cyclocross and gravel riders demanding chain security and efficient power delivery from a 1x drivetrain. We rely on it during race efforts where repeated accelerations, soft terrain, and uneven traction place constant stress on the chainring interface. Designed by absoluteBLACK, it brings modern 1x performance to legacy 5-bolt road cranksets.

The oval profile features carefully tuned ovality and timing to reduce torque spikes and improve traction, especially during steep or slippery climbs. Narrow-wide tooth shaping locks the chain in place, allowing riders to eliminate chain guides and simplify their setup. CNC-machined from 7075 aluminum with durable anodizing, the ring maintains stiffness while shedding mud efficiently to keep engagement consistent throughout a race.

A built-in 1.5mm offset toward the frame improves chainline for quieter operation on 1x drivetrains. This chainring is best suited for cyclocross racers and gravel riders building lightweight, reliable 1x setups where chain retention, smoother power delivery, and simplified drivetrains are critical to performance.
