Grappler Sidekick Pro Flux Aluminum GR Enduro Front MTB Wheel

Grappler Sidekick Pro Flux GR Enduro Aluminum Wheels are a groundbreaking revolution in MTB, at an incredible value. Tested over multiple World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results.

Second-generation Sidekick Pro J-bend hubs are 140g lighter and feature a wider 9°/13°/18° adjustable deadband that eliminates pedal kickback, enhancing suspension performance and filtering drivetrain shock and vibration before it reaches the rider. A magnetic pawl-retraction system, combined with new bearings and seals, reduces drag, making these wheels the fastest-rolling we have ever tested.

Low-profile Flux Pro Aluminum rims set new standards in compliance, strength, weight, and performance. Flux 55 Pro Aluminum Rims provide exceptional durability and ample compliance in 29" front and rear wheels. 27.5" rear wheels are built with buriier Flux 66 GR rims to withstand the added abuse of mixed-wheel gravity use.

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 for both pros and enthusiasts.

• Front-tuned build: spoke pattern, hub flange spacing, and rim lay-up are optimized for steering precision and arm-fatigue reduction on long descents.
• Front axle: 110×15mm Boost for compatibility with modern Enduro forks.
• Sidekick anti-kickback hub technology eliminates kickback and filters drivetrain vibration, improving ride feel and suspension performance
