Synthesis Enduro Boost Wheel - 27.5in

What Our Gearhead® Experts Are Saying:

"I’m seriously impressed with how much better the tuned ride feel is. The softer front keeps me planted in sketchy corners, and the stiffer rear gives me power when climbing and confidence at speed. These aren’t just strong—they’re smart."

Crankbrothers Synthesis Enduro Alloy Wheels bring system-specific engineering to the alloy category, tuning each wheel independently to meet the demands of modern enduro riding. Unlike traditional wheelsets, the front and rear Synthesis wheels are purpose-built with different widths and compliance levels to match the dynamic load patterns of aggressive riding.

The front wheel uses a wider 29.5mm internal rim to round out the tire profile, boosting grip and confidence in turns while improving compliance to soak up chatter. The rear wheel, in contrast, uses a narrower profile and a stiffer build for enhanced tracking through technical sections and increased power transfer under load. Together, they offer a more controlled, responsive feel across diverse terrain, whether you're leaning into loam or hammering over rock gardens.

Each wheel is constructed from strong, lightweight 6013 T6 alloy with a welded and sleeved joint for added durability. The 6-bolt hub system uses Sapim spokes and offers 17º engagement to keep power response quick and reliable. Whether you're racing stages or lapping your favorite trails, this front-and-rear-tuned system lets your bike ride stronger, smoother, and smarter.
