Tirelessly engineered for gravity riders who demand performance and durability on a budget, the Grappler Sidekick Flux 66 wheels are a game-changer in the world of Enduro, Bikepark, and Downhill.

They feature the same Sidekick anti-kickback mechanism and 6069-AL rim extrusions as our Pro-level Aluminum wheels, with a more value-oriented, yet huckproof configuration.

The 9°/13°/18° adjustable deadband in Sidekick Hubs eliminates pedal kickback by absorbing chainstay growth at the source, enhancing suspension performance, and filtering drivetrain shock and vibration before it reaches the rider.

Incredibly resilient, low-profile Flux 66 Aluminum rims deliver excellent strength with the compliance to enhance traction and control, reduce fatigue, and provide a lively ride feel.

Nearly silent hub operation combined with a smoother, more comfortable ride, means every track and trail becomes a whole new experience and you can push your limits harder and longer.

Front-tuned build: spoke pattern, hub flange spacing, and rim lay-up are optimized for steering precision and arm-fatigue reduction on long descents.
Front axle: 110×15mm and 110×20mm Boost (convertible) for compatibility with modern Gravity forks.
Sidekick anti-kickback hub technology eliminates kickback and filters drivetrain vibration, improving ride feel and suspension performance
