Grappler Sidekick Pro Flux Aluminum GR Enduro Rear MTB Wheel - 27.5" 148x12mm Boost Microspline Grappler Sidekick Pro Flux GR Enduro Aluminum Wheels represent a groundbreaking revolution in mountain biking, delivering elite performance at an incredible value. Tested over multiple World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results. The rear-tuned build features optimized drive-side stiffness and reinforced lacing to deliver crisp power transfer with minimal flex when loading the rear wheel. The 27.5" rear wheels are built with the burlier Flux 66 GR rims to withstand the added abuse of mixed-wheel gravity use. At the heart of the wheel is the second-generation Sidekick Pro J-bend hub, featuring a wider 9°/13°/18° adjustable deadband that eliminates pedal kickback, enhances suspension performance, and filters drivetrain shock and vibration. A magnetic pawl-retraction system, combined with modern bearings and seals, reduces drag for whisper-quiet, fast-rolling operation. Built using durable AL-6069 welded alloy with a 30mm internal width, this handbuilt wheel uses a double-butted 28-spoke build with Sapim D-Light spokes and locking brass nipples for ultimate longevity and a responsive ride feel. Key Features Sidekick Anti-Kickback Hub: Features an adjustable deadband (9°, 13°, 18°) that eliminates pedal kickback and filters drivetrain vibration to improve suspension performance. Rear-Tuned Build: Optimized drive-side stiffness and reinforced lacing deliver crisp power transfer with minimal flex under load. Flux 66 GR Rim: Burlier low-profile, hookless 30mm internal width rim crafted from AL-6069 alloy designed specifically to withstand the rigors of 27.5" gravity and mixed-wheel riding. Free Speed & Silence: Magnetic pawl-retraction system delivers exceptionally low drag and whisper-quiet operation. Handbuilt Precision: Assembled with 28h Sapim D-Lite double-butted spokes and Sapim Secure Lock brass nipples for longevity. e-Bike Compatible: Fully certified and built to handle the demands of modern e-MTBs.
