The Grappler Sidekick Flux Aluminum Rear Wheel represents a major leap forward in enduro and downhill wheel technology. Tested over two full World Cup seasons by some of the fastest riders on the planet, this wheel consistently delivers podium‑level performance and unmatched ride quality.

At its core is the Sidekick hub system, featuring an adjustable deadband that eliminates pedal kickback, allowing your suspension to work freely and predictably. By filtering out drivetrain vibration before it reaches the rider, the wheel improves traction, stability, and overall comfort—especially on high‑speed, high‑impact terrain.

The low‑profile Grappler Flux rim sets new benchmarks for compliance, strength, and weight. The result is a wheel that feels lively and controlled, offering smoother tracking, reduced rider fatigue, and a more engaging ride experience than traditional stiff, “wooden” rims.

Combined with a 29" diameter, 30mm internal width, 28‑hole construction, and a 148x12mm Boost Microspline hub, this wheel is built for modern aggressive riding and wide‑range drivetrains. The near‑silent hub operation adds to the refined feel, letting you focus on the trail—not the noise.
