e*thirteen Sidekick Wheels & Hubs

Introducing the all-new e*thirteen Sidekick hubs and Grappler Flux rims. Sidekick hubs isolate the drivetrain from the rear suspension, eliminating pedal kickback and improving rider speed, control, grip, and comfort on descents. Grappler Flux rims deliver the durability that racers trust, with engineered compliance for more grip and comfort in a low-profile design. Sidekick hubs are featured on Grappler Sidekick Flux and Sylvan Sidekick wheels, available now on and from distributors around the world.
