Grappler Sidekick Pro Flux Aluminum GR Enduro Rear MTB Wheel - 29" 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.
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.
The low-profile Flux Pro Aluminum rims set new standards in compliance, strength, and weight. Built using durable AL-6069 welded alloy with a 30mm internal width, the Flux 55 Pro rims provide exceptional bump absorption, tracking, and traction on 29" wheels. Handbuilt to exacting precision with a double-butted 28-spoke build using Sapim D-Light spokes and locking brass nipples, this rear wheel provides a responsive, dynamic ride feel.
