Synthesis V2 Alloy Enduro i9 Boost Wheel - 27.5in

What Our Gearhead® Experts Are Saying:

"This wheel just rips. The I9 hub is lightning fast, and the rear wheel doesn’t flex when I’m charging through rocks or dropping into tech lines. It holds true, rolls smooth, and has that dialed feel that makes me ride faster without thinking twice."

Every second counts when we're threading technical lines, and the Crankbrothers Synthesis Alloy 2.0 Enduro 27.5in Boost Wheel with the Industry Nine 1/1 hub is built to handle it all, and fast. Tuned for compliance in the front and stiffness in the rear, this wheel is made to push limits with precision and control, while the I9 hub delivers a responsive 4° engagement for lightning-quick acceleration out of every corner.

The 30mm front rim improves tire shape for added grip and traction, paired with a 28-spoke build to absorb vibrations and track better on off-camber terrain. The rear gets stiffer and stronger with a 28.5mm inner rim and a 32-spoke count, allowing us to maintain line choice and control at high speed. With durable 6069 alloy construction and a shot-peened finish, the rim stands up to abuse. This setup is ready to race, rally, or ride until dark.
