Named after a famous redwood-covered road climb in Santa Cruz our Zayante road 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 aluminum spindle. Add its beautifully sculpted hollow-forged alloy crank arms and you have a massive amount of stiffness and power transfer to flatten climbs. Praxis Works cold forged chainrings (included) and M30 bottom brackets (required and sold separately) round out the Zayante package for a super-efficient road crank with top notch Praxis shifting. The Zayante M30 can be installed in a BSA BB86 386EVO BB30 PF30 T47 BBRight or older Specialized OSBB road frame.
