e*thirteen's Sidekick rear hub eliminates pedal kickback by fully decoupling the drivetrain from the rear wheel while coasting, so the suspension works as designed instead of fighting chain tension.

Highlights

  • 28-hole, 157x12 Super Boost, XD driver, 310g
  • Tool-free 3-position deadband (9°/13°/18°) tunes the anti-kickback effect
  • Near-zero freewheeling drag, near-silent coasting
  • 17mm 7075 alloy axle, ASTM 5 rated to 150kg
  • Lifetime bearing warranty, 10 years on all other parts

How Sidekick works

A pusher-activated magnetic pawl mechanism disengages the freehub from the hub shell on the coast, isolating pedal feedback from the suspension. e*thirteen's own testing shows up to 44% more time spent in the optimal 11–70% of suspension travel versus a conventional hub.

Compatibility & fit

28-hole, 157x12 Super Boost rear spacing, XD driver, 6-Bolt disc mount. E-MTB compatible. Pair with an e*thirteen Sidekick front hub, and have the Tune workshop build or true the wheel.
