In Downhill, victory is decided by fractions of a second. You need a wheelset that provides the ultimate in control, stability, and durability. The Crankbrothers Synthesis DH range is built on a revolutionary concept: a tuned system with front- and rear-specific wheels. This approach addresses the different forces each wheel endures. The front wheel is built for compliance. It features a wider internal rim width, a lower spoke count, and lighter gauge spokes. This allows the wheel to flex vertically, absorbing impacts from rocks and roots, which enhances grip and gives the rider more control. It tracks the ground with precision, reducing deflection and allowing you to hold your line with confidence. In contrast, the rear wheel is built for stiffness and strength. It uses a narrower internal rim width to support the tire under heavy cornering loads, a higher spoke count, and stronger spokes. This creates a wheel that is incredibly stable, tracks predictably, and can withstand the massive impacts common in DH racing. The result is a wheelset that steers with surgical precision from the front while providing an unshakeable, bombproof foundation in the back. Proven on the world's toughest tracks with multiple Downhill World Cup wins, the Synthesis DH system gives you a tangible competitive advantage. Available in premium carbon for ultimate performance and robust alloy for season-long durability.
