The Digirit Carbon Cog is a premium full-carbon rear cog designed for fixed gear, track bike, and single speed drivetrain setups. Built with a special fiber layup and one-piece carbon construction, it offers a refined balance of low weight, strength, and wear resistance for riders who want a clean and high-performance drivetrain.
Digirit applies its long-term experience in structural engineering and precision manufacturing to bicycle component development. With patented nano-powder processing, the brand improves tooth wear performance while maintaining the lightweight advantages of carbon fiber.
Based in Taiwan, Digirit has years of experience in high-end consumer electronics housing design, structural engineering, and manufacturing problem solving. The brand later brought this expertise into cycling, focusing on carbon chainrings, carbon cogs, 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 carbon cog is available in 14T, 15T, 16T, 17T, and 18T options, and is compatible with 1/2" x 1/8" chains. Digirit and Miche type options are available. It must be used with the corresponding ADAP carrier base, so please confirm compatibility before installation.
Note
Always use the proper tool for installation and removal. Do not use an unsuitable general wrench, as it may damage the cog. Normal installation force is sufficient. Do not strike the carbon cog from the side, as side impact may damage the carbon fiber structure.
