Praxis Works DOON Carbon Road Crankset

The Praxis Works DOON Carbon Road Crankset was developed to be a pro-level road crankset. Named after one of the most famous road climbs in Santa Cruz, California, the DOON is made from Praxis’ C.R.A.F.T carbon process which makes it ultralight and stiff. It uses a 30 mm spindle and an updated preload collar ensures reliability and easy adjustment. In addition, a new finish to the LevaTime II X-Chainrings means a clean look with the same reliable shifting.

The LT II X-Chainrings are highly versatile and are compatible with 10-, 11- and 12-speed (Shimano, SRAM, Campy and KMC) chains. The DOON cranks also use a 3-bolt chainring interface which allows you to run 2X or 1X direct mount chainrings, including aftermarket rings.

The DOON Carbon crankset uses a 30 mm spindle, making it compatible with 30 mm bottom brackets. The LevaTime II X-Chainrings also work with 10-, 11- and 12-speed groupsets.

Key Features:

Advice From Our Staff:

With a weight comparable to the lightest cranksets on the market and a 30 mm spindle, the DOON crankset is surely designed for performance. We like the 30 mm spindle which allows it to fit most frames easily and the LevaTime II X-Chainrings work with a wide variety of groupsets.


Other Versions to Consider

Zayante Carbon: We also offer the Praxis Works Zayante Carbon Road Crankset. This carbon road crankset is a bit heavier than the DOON, but is also more affordable. However please note the Zayante uses an M30 spindle.


This crankset is compatible with 30 mm bottom brackets. It also works with Shimano, SRAM, Campy and KMC 10-, 11- and 12-speed groupsets.
