Praxis Cadet M30 Mountain Crankset


The Cadet M30 is an affordable, performance-oriented mountain bike crankset, that comes equipped with some of Praxis Works' signature features. The Praxis-specific M30 stepped spindle provides the foundation of an extremely stiff and strong pedaling platform, and is compatible with most common bottom bracket shell standards. The cranks arms are solid-forged aluminum for maximum strength and durability, with scalloped back sides for weight savings. The drive side crank arm is equipped with 3-bolt Sram/Truvativ direct mount splines. Praxis' direct mount chainrings feature their latest Wave Tech design for superior chain retention on modern single ring drivetrains, and these are available for either standard or Boost frames.


Crank Length - The Cadet is available in two arm lengths, 170 and 175mm.

Chainring - Options include Praxis' full line of Wave Tech 1X chainrings, including tooth counts from 26 to 36, with options for standard 49mm chainline (DM-A), or Boost 52mm chainline (DM-B). These chainrings are compatible with Shimano and Sram 10 and 11 speed drivetrains, but are not currently compatible with Sram Eagle 12 speed chains.

Bottom Bracket - Praxis' M30 standard is not compatible with other manufacturer's bottom brackets, so a Praxis M30 bottom bracket will be required. Current supported shell standards include BSA (English-threaded), BB30, PF30, and BB90/92. An M30 installation tool set is included with both the BSA and BB30/PF30 bottom brackets. A proper bearing press (such as a headset press) is required for installing the BB90/92 bottom bracket. Praxis manufactures a gauge for checking tolerance of BB90/92 frames.
