The Digirit Track Carbon Chainring is a premium full-carbon chainring designed for track bike, fixed gear, and single speed drivetrain setups. Built with a special fiber layup and one-piece carbon construction, it delivers a refined balance of low weight, strength, and wear resistance for riders who want efficient power transfer and a distinctive drivetrain upgrade.
To prove the durability of its full carbon chainrings, Digirit has completed professional rider testing, a 25,000km wear test, and ISO fatigue testing. Drawing from its experience in precision machining and structural engineering, Digirit also applies patented nano-powder technology to improve tooth wear performance.
Digirit is a Taiwan-based brand with long-term experience in high-end consumer electronics housing design, structural engineering, and manufacturing problem solving. The brand later brought this knowledge into cycling, focusing on carbon chainrings and innovative bicycle components. Digirit has also received recognition from the 2018 TAIPEI CYCLE d&i Awards and the 2018 Golden Pin Design Award.
This Track version comes with a standard 3K carbon finish. Special finishes such as Radial, Checker Square, Dot, Marble, Hair, and UD are also available by request, along with special cutting or custom BCD options. Extra charges may apply for customization.
Note
Do not strike the carbon chainring from the side, as side impact may cause cracks in the carbon fiber structure. Always install with the recommended torque and confirm compatibility with your crankset, chainring bolts, and chain specification.
