Product Description
e*thirteen Grappler Sidekick Flux 66 Aluminum GR Rear Wheel - 27.5", 148x12 Boost, HG, 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 Rear Wheel is a true game-changer for Downhill, Enduro, and bike park riding. This heavy-duty wheel integrates e*thirteen's revolutionary Sidekick anti-kickback hub technology with their resilient 6069-AL rim profiles into a value-packed, huckproof package. This 27.5" configuration is the definitive choice for riders running full 27.5" gravity rigs or those building a highly agile, hard-charging mixed-wheel (Mullet) setup that balances quick cornering response with heavy rock-strike durability.
The defining centerpiece of this wheel is the innovative Sidekick Rear Hub. Featuring an adjustable 9°/13°/18° deadband and a reliable 3-pawl mechanism, this hub eliminates pedal kickback by absorbing chainstay growth directly at the source. By decoupling drivetrain forces from your rear suspension, Sidekick technology allows your rear shock to move completely free of chain tension. This dramatically improves small-bump sensitivity, isolates harsh chain feedback, and filters out drivetrain shock before it ever reaches the rider, allowing you to carry more "free speed" into technical track sections with whisper-quiet, nearly silent trail operation.
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 rider 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 27.5" rear wheel features a heavy-duty 32-hole drilling to increase structural durability and stability across technical, heavy-impact terrain. It is meticulously handbuilt with high-quality double-butted spokes and secure-lock brass nipples, ensuring long-term tension stability and structural longevity under hard cornering and heavy landings. Outfitted with standard 148x12mm Boost spacing, a Shimano HG compatible driver, and a dependable 6-bolt disc mount, this 1125g rear wheel is fully backed by an incredible 10-year manufacturer warranty with comprehensive crash replacement support.
