e*thirteen Grappler Sidekick Flux 66 Aluminum GR Front Wheel - 29", 110x15/20 Boost, Black

Tirelessly engineered for gravity riders who demand top-tier performance and rugged durability on a budget, the e*thirteen Grappler Sidekick Flux 66 Aluminum Front Wheel is a true game-changer for Downhill, Enduro, and bike park riding. This high-performance wheel integrates e*thirteen's revolutionary Sidekick anti-kickback hub technology with their resilient 6069-AL rim profiles into a value-packed, huckproof package. Built specifically for the unique demands placed on a front wheel, it balances premium rock-strike resilience with traction-enhancing compliance.

The defining centerpiece of this wheel is the innovative Sidekick Front Hub configuration. Designed to work in unison with high-performance rear hub systems, this architecture delivers exceptionally low drag and whisper-quiet operation across all terrain. By decoupling the drivetrain forces from your suspension, Sidekick technology isolates harsh chain feedback and filters out structural drivetrain shock and vibration before it ever reaches your hands, letting you carry more "free speed" into technical track sections and braking bumps.

Laced up to the hub is the gravity-specific Flux 66 GR Aluminum Rim. Built from tough 6069 aluminum with a value-oriented sleeved joint, it features a signature 17mm low-profile depth explicitly engineered to optimize radial compliance. This intentional flex filters out punishing trail chatter and rough square-edged rock gardens, acting as an integrated layer of suspension that drastically reduces forearm fatigue. A generous 30mm inner width stabilizes wide gravity tire casings, while broad hookless flanges deliver dependable, set-and-forget tubeless security and superior pinch-flat protection.

This 29" front wheel features a weight-saving and compliance-boosting 28-hole drilling. It is meticulously handbuilt with high-quality double-butted spokes and secure-lock brass nipples, ensuring long-term tension stability and structural longevity. Outfitted with versatile 110x15/20mm Boost spacing and a dependable 6-bolt disc mount, this 1025g front wheel is fully backed by an incredible 10-year manufacturer warranty with comprehensive crash replacement support.
