Tirelessly engineered for gravity riders who demand performance and durability on a budget, the Grappler Sidekick Flux 66 Wheels are a game-changer in enduro, bikepark, and downhill riding.
They feature the same Sidekick anti-kickback mechanism and AL6069 rim extrusion as our Pro-level aluminum wheels, in a more value-oriented — yet still huck-proof — 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 — so you can push your limits harder and longer.
- Rear-tuned build: drive-side stiffness and reinforced lacing deliver crisp power transfer with minimal flex when you load the rear wheel
- Freehub options to match your drivetrain: choose XD, Microspline, or HG
- Sidekick anti-kickback hub technology eliminates kickback and filters drivetrain vibration, improving ride feel and suspension performance
- Enhanced comfort and control: ultra-compliant, low-profile Flux 66 Aluminum rims add radial compliance and traction without reducing steering precision and durability
- Free speed: Sidekick hubs run exceptionally low drag with whisper-quiet operation, carrying more speed than other freehub systems
- 32-spoke rear wheels increase durability and stability in technical terrain
- Handbuilt to exacting precision with AL6069 sleeved rims, double-butted spokes, and secure lock brass nipples for performance, longevity, and value
- Backed by a lifetime hub bearing warranty, a 10-year warranty on all other parts, and a discounted rim crash replacement policy
