Beautifully sculpted: the Zayante crankset by Praxis Works
Named after a famous redwood covered road in Santa Cruz County, the Praxis Zayante 30 mm Hollow Forged crank represents a huge amount of technology in a " Comp" level package. The Zayante combines the benefits of a wide outboard bearing stance with a 30 mm aluminium spindle.
Add in beautifully sculpted hollow forged crank arms and you have a massive amount of stiffness and power transfer. Praxis Works Cold Forged chainrings and M30 bottom brackets round out the Zayante package for what is a very versatile road crank with top notch Praxis shifting.

Please note the Praxis Works installation instructions.
Note: Sub-compact cranksets (tooth count less than 34-50) require the front derailleur to be mounted lower. Check to make sure that your front derailleur can be adjusted lower on your frame before mounting.
Forging Process (Cranks)
With Praxis Works' deep history of complex metal manufacturing, it was natural for them to continue to work with aluminium as the crank line evolves. The Zayante and Girder cranks are made with a unique hollow forging process while the Alba and Cadet cranks are made with a solid forging method. Both of these forging processes align the grain of the metal through the use of massive pressure resulting in light weight, tough, and super durable crank arms.
Attention to detail and proprietary in-house forging allows Praxis Works to control the process from start to finish, and maximize performance from each aluminium part. Combine this with the famous Praxis Works chainrings, and the final product is a beautiful assembly that provides an incredible ride experience.
Cold Forging (Chainrings)
Forging is the process by which metal is shaped applying heavy compressive force. At Praxis, this compressive force comes in the form a very large forging press.
Similar to wood, metal has grain to it. Forging refines that grain structure and improves the physical properties of the 7075 T6 aluminium blanks Praxis Works starts with. With their ring designs, the grain flow can be oriented in the direction of principal stresses (the chain) encountered while riding.
Physical properties (such as hardness and toughness) are also much better in a forging than in the base metal which has grain crystals randomly oriented. The chainrings produced here yield very high strength to weight ratio.
Like all great marriages in life, timing is everything. A large part of Praxis Works LevaTime shifting system is the timing and clocking of the outer and inner rings together. All of the Praxis ring combinations are " Matched Sets" precisely designed in concert for an optimized shifting experience. Praxis engineers spend an obscene amount of time labouring over tooth shape, ramping, and the precise location of shift elevators. All of this is done in order for the inner and outer ring to be in perfect sync at the moment you shift.
The M30 bottom bracket family is for the M30 cranks. The M30 spindles are 30 mm and then have a step-down to 28 mm to lock on the Non Drive bearing. These use a drive side wave-washer for the bearing preload, and a 30 mm Drive bearing with a step down to 28 mm Non Drive bearing. With the superior support of this wide stance, the M30 system takes power transfer to a new level. It elegantly combines the benefits of a stout 30 mm alloy spindle, with the support benefits of an wide-stance bearing to get the best of both worlds.
