Oval GRAVEL 110BCD 1x Chainring

What Our Gearhead® Experts Are Saying:

"I’ve run this on both older 5-bolt and newer 4-bolt Shimano road cranks, and it’s been a standout upgrade. Chain retention is flawless without a guide, and the oval shape really helps smooth power when climbs get loose or steep."

Gravel riding demands consistency when terrain, traction, and pacing are constantly changing, and that’s exactly where the Gravel 1X OVAL 110BCD Premium Chainring shines. Designed by absoluteBLACK for riders running 1x drivetrains on gravel and all-road bikes, it delivers a smoother pedal stroke and reliable chain security across long days that mix pavement, dirt, and everything in between.

The oval profile is tuned to reduce dead spots and smooth torque delivery, helping us stay seated and maintain momentum on loose climbs and rolling terrain. Narrow-wide tooth shaping locks the chain in place without the need for a guide, while a built-in 1.5mm offset toward the frame improves chainline for quieter, more efficient running. CNC-machined from stiff 7075 aluminum with strategic cutouts, the chainring balances low weight with the rigidity needed for loaded gravel efforts. Available for both Shimano 110/5 BCD and 110/4 BCD cranksets, it’s a clean solution for modernizing a wide range of gravel and road cranks into capable 1x setups.
