Grappler Sidekick Flux Carbon Enduro Rear MTB Wheel - 27.5" 148x12mm Boost Microspline

Grappler Sidekick Flux Enduro and Downhill Wheels represent a groundbreaking revolution in mountain biking. Tested over two World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results. The rear-tuned carbon build combines the suspension benefits of Sidekick anti-kickback technology with the unmatched control and comfort of engineered compliance from Grappler Flux carbon rims.

At the heart of the wheel is the Sidekick anti-kickback hub, featuring an adjustable deadband that eliminates pedal kickback, enhances suspension performance, and filters drivetrain shock and vibration before it reaches the rider. A 3-pawl mechanism and whisper-quiet operation ensure exceptionally low drag, allowing you to carry more speed through rough sections.

The low-profile Flux Carbon rims set new standards in compliance, strength, weight, and performance. Handbuilt to exacting precision with a double-butted 28-spoke build using Sapim D-Light spokes and Secure Lock alloy nipples, this wheel provides a responsive, dynamic ride feel that puts stiff, harsh-riding hoops to shame.
