e*thirteen Grappler Sidekick Flux Carbon Rear Wheel Downhill - 29" 157x12mm Super Boost Integrated 7-Speed 9-24T Cassette

Grappler Sidekick Pro Flux GR Downhill Wheels set new benchmarks for durability, comfort, and enhanced control. Tested over multiple World Cup seasons by the world's fastest athletes, these wheels consistently deliver top results on the most demanding gravity tracks. The rear-tuned 32-spoke build features optimized drive-side stiffness and reinforced lacing to increase durability and stability in technical terrain while ensuring crisp power transfer under heavy loads.

At the heart of the wheel is the Sidekick Pro GR hub, built tough with an oversized 17mm alloy axle, new bearings and seals for reduced drag, and a 12°/15°/18° adjustable deadband. This anti-kickback technology decouples the drivetrain from the suspension to eliminate pedal kickback and filter out high-frequency shock and vibration. A magnetic pawl-retraction system ensures dramatic friction reduction while coasting for whisper-quiet, ultra-fast rolling performance.

The strongest low-profile Flux 66 Pro Carbon rims strike an unparalleled balance in compliance, strength, weight, and performance. Handbuilt to exacting precision with double-butted Sapim D-Light spokes and locking brass nipples, this wheel is backed by a lifetime free rim replacement warranty for long-term value.
