Named after a famous redwood covered road in Santa Cruz County, the Praxis Zayante 30mm 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 30mm 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.
