Oval GRAVEL 110BCD 1x Chainring

What Our Gearhead® Experts Are Saying:

"This is my go-to recommendation for riders converting Shimano road cranks to 1x gravel. It’s stiff, quiet, and the oval timing noticeably smooths effort on long, uneven climbs."

The Gravel 1X OVAL 110BCD Premium Chainring is engineered for riders seeking efficient power delivery and dependable chain retention in gravel and all-road 1x drivetrains. We rely on it during long mixed-surface rides where cadence changes, traction shifts, and sustained climbs place constant demands on drivetrain stability. Designed by absoluteBLACK, it brings oval efficiency and narrow-wide security to a wide range of Shimano-compatible cranksets.

The oval profile features 10.5–11.4 percent ovality with timing positioned just after top dead center to reduce torque spikes and promote smoother pedaling under load. Narrow-wide tooth shaping securely engages the chain, allowing riders to eliminate chain guides while maintaining quiet, consistent engagement. CNC-machined from 7075 aluminum and finished with durable anodizing, the chainring remains stiff despite extensive cutouts, preserving power transfer on rough terrain.
