Praxis Zayante Carbon Crankset

The Praxis Zayante Carbon Crankset is Praxis Works' flagship road double, built for riders who want a full carbon arm without stepping into the boutique pricing tier that defines most high-end drivetrain components. It sits at the top of the Praxis road crankset lineup and delivers a meaningful weight reduction over alloy options while maintaining the stiffness you need to transfer power cleanly through every pedal stroke.

Praxis builds the Zayante around their M30 bottom bracket interface, using an oversized 30mm spindle that's pressed directly into the carbon arm — a design choice that eliminates the flex point found at the arm-to-spindle junction in traditional cranksets. The carbon layup is engineered to keep the arm stiff laterally while allowing enough compliance along the length to smooth out road vibration on longer rides. Praxis also uses their own chainring bolt pattern, designed to accept both standard Praxis rings and a wide range of aftermarket options, so you're not locked into a single chainring ecosystem as your riding evolves.

Design Benefits

1. Integrated spindle construction for improved stiffness: By bonding the M30 spindle directly into the carbon arm rather than using a separate interface, Praxis reduces flex at one of the most mechanically stressed points in the drivetrain — translating to more responsive power delivery on climbs and out-of-saddle efforts.
2. Compact gearing covers a broad spread of road terrain, from rolling group rides to steeper mountain passes, without requiring a change to a wide-range cassette. It's a versatile setup that works equally well on a training bike and a race-day build.
3. The full carbon arm construction keeps weight down without sacrificing the structural integrity required for road racing and aggressive riding. For riders upgrading from an alloy crankset, the difference is immediately noticeable in both handling feel and reduced rotational mass.
