Praxis Doon Carbon Crankset

This crankset uses the Praxis M30-THRU spindle system. You will need to use a Praxis M30-THRU specific bottom bracket to ensure proper fitment and bearing preload.

Yes, the Doon Carbon Crankset is fully compatible with 10, 11, and 12-speed drivetrains, including SRAM Flattop chains, Shimano, and Campagnolo systems.

Crank arm length is largely a matter of personal preference and bike fit. Generally, shorter arms like 165mm can help with hip clearance and higher cadence, while longer arms like 175mm may provide more leverage for riders who prefer a lower cadence.

The Q-factor is 147mm. This measurement represents the distance between the outside of the crank arms, and a narrower Q-factor is often preferred by cyclists looking for a more natural, efficient pedaling stance.

Yes, the Doon uses a SRAM-style 3-bolt direct mount interface. This makes it straightforward to swap your chainrings if you decide to change your gearing setup in the future.

LevaTime II is designed with specific shift ramps and pins that help the chain move smoothly between rings under load. It provides crisp, reliable shifting performance that rivals the major drivetrain manufacturers.
