Sylvan Sidekick Aluminum Wheels bring pro-level performance and durability to aggressive trail and all-mountain riding — without the pro-level price tag. The 2nd-gen adjustable deadband (9°/13°/18°) kills pedal kickback and filters drivetrain shock/vibration before it hits the rider. Set it to 9° for snappier, traditional-hub-feel engagement on climbs, or crank up the deadband tool-free as terrain gets rougher for maximum anti-kickback. On short/mid-travel bikes, that means a smoother, less fatiguing ride and more usable suspension — with zero change to the frame's kinematics. Rear-specific, low-profile Flux Aluminum rims raise the bar on compliance, strength, weight, and performance. The rear-specific Flux 54 adds durability without dulling ride feel. Together, Sidekick + Flux deliver more comfort, speed, and control, plus a lively ride feel. Predictable suspension performance, better traction and tracking, less fatigue, and near-silent hubs — built for a confident ride whether you're racing or just riding for fun. Features 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, 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 Aluminum rims add radial compliance and traction without reducing steering precision and feel Flux 54 Pro rims : deliver balanced comfort and durability Free Speed: Sidekick has exceptionally low drag and whisper-quiet operation, carrying more speed than other freehub systems Lively Ride Feel: The low profile height combined with double-butted 28-spoke build makes for a responsive and dynamic ride Handbuilt to exacting precision with AL 6069 sleeved rims, double-butted spokes, and secure lock brass nipples, for performance, longevity, and value *Tubeless valve is not included
