Praxis Zayante Carbon-S Crankset

The Praxis Zayante Carbon-S Crankset is Praxis's performance-oriented 2x road crankset, built for riders who want a genuinely capable carbon crank without stepping into the top tier of the market. It sits at the heart of Praxis's road lineup — above their alloy offerings and positioned as a serious option for long-distance riding, gran fondos, and dedicated road training. The defining feature here is the carbon arm construction, which keeps weight down while providing the stiffness you need when the road kicks up.

Praxis builds the Zayante Carbon-S around their proven M30 bottom bracket interface, using oversized 30mm chromoly spindle technology that's designed to improve power transfer and reduce flex at the spindle junction. The chainrings are steel, which Praxis intentionally specifies for durability and shift quality over the long haul — a practical choice for riders logging real miles. Three chainring configurations are available (48x32, 50x34, and 52x36), covering everything from aggressive climbing gearing to more traditional road setups. Arm length options span 165mm through 175mm, making it a genuinely fit-friendly option across a wide range of riders.

Design Benefits

1. Carbon arms with a practical steel ring package: The carbon arm construction reduces rotational weight where it matters most, while steel chainrings hold up to sustained use and deliver consistent shifting across a wide range of groupset combinations — a balance that makes sense for riders who put in serious mileage.
2. M30 spindle interface for reliable power delivery: Praxis's M30 platform uses a larger-diameter spindle than traditional square-taper or older external-bearing designs, intended to minimize flex and keep your pedal stroke feeling direct. It's also compatible with a broad range of Praxis and third-party bottom bracket shells with the right adapter.
3. Wide gear range selection for varied terrain: With three distinct chainring combinations on offer, the Zayante Carbon-S accommodates road riders across a broad spectrum — whether you're chasing flatter group rides on a 52x36 or looking for the extra mechanical advantage of a 48x32 on hilly routes.
