The e*thirteen Sidekick Hub features a unique anti-kickback drive mechanism with adjustable deadband, providing smooth suspension performance, reduced fatigue, and near-silent operation for an unparalleled riding experience.

The Sidekick Hub is a revolutionary milestone in mountain bike wheels. Designed and tested with the world’s top teams and racers over multiple seasons, the Sidekick Hub promises to enhance the suspension performance of any full-suspension mountain bike. Its groundbreaking freehub mechanism disengages the drivetrain from the rear wheel when coasting, and an adjustable deadband filters kickback and chain vibration before it reaches the pedals, virtually eliminating pedal feedback effects on suspension. With the drive mechanism disengaged from the ratchet ring, drag is significantly reduced. The result is an impeccably smooth ride over the roughest terrain, improved traction, heightened speed and control, and reduced fatigue. Its nearly silent operation immerses you in the outdoor experience, letting you hear nothing but the wind in your ears and your tires on the trail.

  • Adjustable pawl-pusher allows tool-free tuning of deadband between 12°, 15°, and 18° to suit rider preference, bike type, and terrain
  • Chain tension filtered by the deadband ensures suspension is unhindered by resistance from pedal kick-back, resulting in improved, more consistent performance, and simpler setup
  • Durable 60T ratchet ring with innovative pusher driven pawl system provides silent operation and reduced drag by remaining disengaged unless pedaling
  • Reduced kickback, chainslap, and vibration mean a quieter, more comfortable ride
  • Ultimate reliability: Proven on the World Cup and fully serviceable and rebuildable, so you can push your limits with confidence

    What is Sidekick?

    The Sidekick Hub by e*thirteen is a revolutionary rear mountain bike hub designed to enhance suspension performance by eliminating pedal kickback and filtering chain vibration. 

  • E*Thirteen

    How does Sidekick Work?

    A proprietary freehub mechanism disengages the drivetrain from the rear wheel when coasting, and an adjustable engagement deadband filters kickback and chain vibration before it reaches the pedals, isolating all pedal feedback from the suspension.

  • E*Thirteen

    What is Pedal Kickback?

    Pedal kickback occurs when suspension movement applies tension to the chain, causing unwanted pedal movement and compromising suspension performance.
