Grappler Sidekick Flux Enduro and 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 nearly silent hub operation create a more confident and immersive ride experience for both pros and enthusiasts.
