More about e*thirteen Sidekick Hubs

Pedal kickback degrades suspension performance even when you can't feel it. Chain tension from suspension movement pulls against the pedals, robbing traction and adding fatigue. Sidekick is the only hub that fully disconnects the drivetrain while coasting, eliminating kickback at the source rather than just damping it. Pinkbike named it Innovation of the Year, calling it "the most elegant take on chain-force mitigation we've seen to date."

With the drive mechanism disengaged from the 60T ratchet ring, drag drops to nearly zero. The hub spins like a front wheel, carrying more speed through rough sections without losing momentum. And instead of the angry-bee ratchet of a conventional freehub, you hear your tires and the trail. Riders consistently call the silence one of their favorite features.

The Design & Innovation Award recognized Sidekick for delivering "noticeably more responsive suspension, fewer vibrations, and significantly reduced rider fatigue." BikeRadar found it made "a marked difference to suspension performance" with "seemingly more time to think about your lines and body position." MBR said it feels "like riding chainless" with the rear wheel tracking better under braking.

Adjustable deadband lets you tune engagement to your bike, riding style, and terrain: 12°, 15°, or 18°. Tool-free pawl-pusher adjustment means you can dial it in trailside. Rear hubs available in Boost, Super Boost, and DH spacing with XD, Microspline, HG, and integrated 7-speed cassette options. Pair with the matching Sidekick front hub for a complete, race-tested wheelset.
