CX Round 110/130 BCD Chainring keeps chains secure through rough remounts and race pace surges

What Our Gearhead® Experts Are Saying:


"I’ve run this ring through sloppy cyclocross races and fast gravel sessions, and it’s been rock solid. Chain retention is excellent without a guide, and the mud-shedding tooth profile really does make a difference when conditions turn ugly."


When courses turn slick and power delivery matters most, we trust the CX Round 110/130 BCD Chainring to keep our drivetrain quiet and dependable. absoluteBLACK designed this ring specifically for cyclocross, where remounts, off-cambers, and deep mud demand absolute chain security without extra hardware slowing us down. From early-season training laps to race-day chaos, it delivers the consistency we need to focus on lines and effort, not dropped chains.


The narrow-wide tooth profile grips the chain tightly enough to eliminate the need for a chainkeeper, saving weight and simplifying the setup. CNC-machined from 7075 aluminum and finished with durable anodizing, the ring holds up to gritty conditions while shedding mud efficiently thanks to carefully shaped chamfers. Whether paired with a clutch derailleur or a simpler setup, it’s a straightforward upgrade that makes a noticeable difference every ride.
