The Digirit Track Carbon Chainring is a high-end full carbon chainring designed for track bike and single speed drivetrain setups. It is made for riders seeking lightweight performance, efficient power transfer and a premium custom build finish.
This chainring features a full carbon one-piece construction, special fiber layup and patented nano-powder process, balancing light weight, strength and wear resistance. Compared with standard aluminum chainrings, the carbon construction also gives the drivetrain a distinctive and refined visual identity.
To verify durability, Digirit has tested its full carbon chainrings with professional riders, completed a 25,000km wear test and passed ISO fatigue testing. The brand also applies its metal processing experience to carbon drivetrain components, using a patented nano-powder process to improve tooth wear performance and long-term stability.
Digirit is based in Taiwan. The team has long-term experience in high-end consumer electronics housing design, structural engineering and precision manufacturing. They bring this background into the cycling industry, focusing on carbon chainrings and innovative bicycle components. The brand has also received recognition from the 2018 TAIPEI CYCLE d&i Awards and the 2018 Golden Pin Design Award.
This Track series model uses a BCD 144, 5-bolt standard with a 2.9mm tooth thickness and is compatible with 1/2" x 1/8" chains. The standard finish is 3K carbon, with optional special patterns including Radial, Checker Square, Dot, Marble, Hair and UD. Special BCD, special patterns and custom machining may be available upon request, subject to production conditions and additional cost.
If you are looking for a Taiwan-made chainring that combines low weight, durability, structural strength and a premium carbon finish, the Digirit Track Carbon Chainring is a standout choice for single speed drivetrain upgrades.
⚠️ Please note: this product includes one carbon chainring only. Crank, chainring bolts, chain, cog, bottom bracket and display props are not included.
⚠️ Do not strike, drop or impact the chainring from the side, as this may cause cracks in the carbon structure.
⚠️ Before installation, confirm crank BCD, bolt pattern, chainring bolts, chain and drivetrain compatibility.
⚠️ Recommended chainring bolt torque is 6Nm–8Nm. General track bike recommendation is around 8Nm, but final torque should be confirmed according to crank and bolt specifications.
⚠️ Carbon drivetrain components affect riding safety. Professional installation, tightening and inspection are recommended.
⚠️ Special patterns, special machining and special BCD options may require confirmation of production conditions, lead time and additional cost.
