absoluteBLACK Oval CX 110BCD 1x Chainring Black, 40t, 5h+bolts

What Our Gearhead(R) Experts Are Saying: "I've set this up on several older road cranks for 1x cyclocross builds, and it's been incredibly reliable. Chain retention is excellent without a guide, and the oval shape really helps smooth out power on punchy climbs."Cyclocross courses punish drivetrains with mud, off-cambers, and constant accelerations, and that's exactly where the CX 1X OVAL 110/5 BCD N/W Traction Chainring thrives. Designed by absoluteBLACK for 1x cyclocross and gravel setups using road cranks, it delivers dependable chain security while smoothing out power when traction is limited and effort spikes come fast. The oval profile reduces dead spots in the pedal stroke, helping us stay seated and maintain momentum through rutted climbs and greasy corners. Narrow-wide teeth grip the chain tightly, eliminating the need for a chain guide, while a built-in offset toward the frame improves chainline for quieter, more efficient running. Machined from durable 7075 aluminum and shaped to shed mud, it's a purpose-built solution for riders pushing older 5-bolt cranksets into modern 1x territory.
