Praxis Works DOON Carbon-GR Gravel Crank Arms

The Praxis Works DOON Carbon-GR Gravel Crank Arms are pro-level gravel cranks designed for modern wide-chainline drivetrains. It uses full carbon crank arms paired with an aluminum 30 mm spindle. This design keeps weight low at around 342 grams for the arm set while maintaining strong power transfer. Praxis builds the DOON-GR around its C.R.A.F.T. carbon manufacturing process to balance stiffness, weight and ride feel.

The modular design also supports aftermarket 3-bolt power meter spiders for added performance tracking. This same 3-bolt direct mount interface allows easy setup with 1x or 2x chainring configurations. The crank delivers a 48 mm chainline for 1x and 47 mm for 2x setups, making it ideal for Shimano GRX and SRAM “Wide” gravel groups.

Advice From Our Staff:

With weight on par with some of the lightest cranksets out there and a 30 mm spindle, the DOON Gravel crankarms have a clear focus on performance. The 30 mm spindle makes fitment easy across most frames, which is always a plus. The 3-bolt interface also opens up plenty of options for chainrings and power meters. It is a versatile setup that works well for a wide range of gravel builds.
