Grappler Sidekick Pro Flux Aluminum GR DH Rear MTB Wheel

Grappler Sidekick Pro Flux GR Aluminum Downhill Wheels set new benchmarks for durability, comfort, and enhanced control, with value-performance that can't be beat. Tested over multiple World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results.

Sidekick Pro GR hubs are built tough enough for the World's roughest tracks, yet shave serious grams with Sidekick 2.0 features such as a lightweight, oversized 17mm alloy axle, new bearings and seals for less drag, and a 12°/15°/18° adjustable deadband. The deadband in Sidekick hubs decouples the drivetrain from the suspension, eliminating pedal kickback, enhancing suspension performance, and filtering drivetrain shock and vibration before it reaches the rider. Pawls retracted during coasting means dramatically less friction and the fastest rolling wheels we've ever tested.

Our low-profile Flux 66 Pro Aluminum rims deliver balanced compliance, strength, and performance at an exceptional weight for aluminum wheels.

Together, these technological marvels offer increased comfort, enhanced speed and control, and a lively ride feel that won't disappoint. Efficient, predictable suspension performance, added traction and tracking, reduced rider fatigue, and nearly silent hub operation create a more confident and immersive ride experience.

Whether it's competitive DH race or smashing laps at the bike park, pros and enthusiasts alike will find exceptional value and performance in Grappler Sidekick Flux GR Downhill wheels.
