Synthesis Enduro Boost Wheel - 29in

What Our Gearhead® Experts Are Saying:
"These wheels surprised me. The front tracks through chunk like it’s glued down, and the rear feels tight and efficient. It’s one of the few setups that actually rides as claimed—super confidence inspiring."

Engineered with a split personality that makes perfect sense on the trail, the Crank Brothers Synthesis Enduro Boost Wheel 29in redefines control through front-to-rear tuning. The concept is simple but effective—optimize the front wheel for tracking and compliance, and the rear for stiffness and support. The result? Balanced handling that inspires confidence through unpredictable terrain and heavy hits.

Constructed from lightweight alloy with an asymmetric profile, the Synthesis Enduro wheels use specific spoke counts and tensions to dial in performance: the front rim features lower tension and more compliance for improved grip and feel, while the rear rim is built stiffer to hold lines under load and absorb big impacts. Boost spacing and a high-performance hub design round out a wheel system made to go fast, hit hard, and keep coming back for more.

Whether you're racing enduro, smashing shuttle runs, or taking on backcountry tech, this wheel delivers refined performance where it counts the most—on trail.
