For Aggressive Trail and All Mountain riders who want performance without the price tag — or the compromise. The Sidekick Flux Aluminum Wheelset shares its Sidekick anti-kickback mechanism and 6069-AL rim extrusions with e*thirteen's Pro-level aluminum wheels, in a more value-oriented, equally resilient build. Sidekick Hubs use a 9°/13°/18° adjustable deadband to eliminate pedal kickback at the source, absorbing chainstay growth and filtering drivetrain shock and vibration before it reaches you — improving both suspension performance and ride feel. The low-profile Flux rims add engineered compliance for better traction, control, and all-day comfort. Lightweight Flux 43 rims up front maximize compliance, while the more robust Flux 54 rims out back balance comfort with added durability. And because every Sidekick hub runs near-silent, you get a more immersive ride in the backcountry. The result: a Trail and All Mountain wheelset that upgrades any full-suspension bike with a playful, dynamic feel — at a genuinely incredible price.
