Grappler Sidekick | Flux Aluminum | Rear Wheel | Downhill | 27.5" x 30mm | 32 Hole | 157x12mm | 7 spd 9-24t DM Cassette | Black (WH5GKA-216)

The e*thirteen Grappler Sidekick Flux Aluminum Rear Wheel is a World‑Cup‑proven downhill wheel built for maximum suspension freedom, traction, and durability. Featuring a 27.5" x 30mm Flux Alloy rim, a 12x157mm Sidekick anti‑kickback hub, and a 7‑speed 9–24T cassette interface, it delivers exceptional compliance, reduced pedal kickback, and near‑silent performance for aggressive DH and e‑MTB riding.

The ethirteen Grappler Sidekick Flux Aluminum Downhill Rear Wheel* represents a major leap forward in DH wheel performance. Developed over two full World Cup seasons and tested by some of the fastest riders in the world, this wheel blends advanced anti‑kickback hub technology with engineered rim compliance to deliver unmatched control, comfort, and speed.

At the heart of the system is the Sidekick hub, featuring an adjustable deadband that eliminates pedal kickback and frees your suspension to work exactly as intended. By filtering drivetrain shock and vibration before it reaches the rider, the wheel improves traction, tracking, and overall ride feel—especially on rough, high‑impact downhill terrain.

The low‑profile Grappler Flux Alloy rim sets new standards for compliance, strength, and weight. Its engineered flex pattern adds radial compliance and traction without sacrificing steering precision, giving the wheel a lively, responsive character that outperforms stiff, wooden‑feeling rims.

Handbuilt with Sapim D‑Light spokes, self‑locking alloy nipples, and a fully serviceable hub system, this wheel is built for riders who demand race‑level performance and long‑term reliability. Compatible with 7‑speed DH cassettes (9–24T) and Shimano/SRAM 10/11‑speed chains, it’s ready for modern downhill and e‑MTB setups.
