Digirit

Digirit is a Taiwanese manufacturer that has made full carbon chainrings the focus since the company's founding in 2011. The brand built its reputation on the track — where stiffness under sprint loads, low rotating weight, and reliable tooth engagement aren't nice-to-haves, they're requirements. That foundation carried over to time trial and triathlon builds, and Digirit has since expanded into 2x road setups with chainring pairs designed for Shimano Dura-Ace and other modern high-speed drivetrains.

The RA Cycles Digirit collection covers the full range: 2x carbon chainring sets matched to Dura-Ace R9200 cranksets — both standard and aero variants — and a dedicated track ring for 5x144mm BCD track setups. Every ring is engineered for precision over alloy alternatives, with weight and stiffness that shows up where it counts.
