Grappler Sidekick Flux Downhill Wheels are a groundbreaking revolution in MTB wheels. Tested over two World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results. Sidekick hubs feature an adjustable deadband that eliminates pedal kickback, enhancing suspension performance and filtering drivetrain shock and vibration before it reaches the rider. Low-profile Grappler Flux rims set new standards in compliance, strength, weight, and performance. Together, these technological marvels offer increased comfort, enhanced speed and control, and a lively ride feel that puts wooden-feeling hoops to shame. Efficient and predictable suspension performance, added traction and tracking, reduced rider fatigue, and near-silent hub operation create a more confident and immersive ride experience for both pros and enthusiasts.

Features
Improved Suspension Performance: Sidekick hubs decouple the drivetrain from the suspension, eliminating kickback at its source and filtering drivetrain vibration to improve ride feel and suspension performance.
Free Speed: Sidekick delivers exceptionally low drag, carrying more speed than other freehub systems.
Enhanced Comfort and Control: Ultra-compliant, low-profile Flux carbon rims add radial compliance and traction without reducing steering precision and feel.
Lively Ride Feel: Low-profile height combined with a double-butted 28-spoke build adds wheel strength while maintaining a responsive and dynamic ride.
Ultimate Reliability: Proven on the World Cup and fully serviceable and rebuildable, so you can push your limits and ride with confidence.
