Product Description

e*thirteen Sidekick GR Rear MTB Hub – Boost 148mm, Microspline, 28H

The Sidekick GR Rear Hub represents a major leap forward in MTB hub technology. Developed and tested over multiple seasons with top World Cup teams, it enhances the suspension performance of any full‑suspension bike by virtually eliminating pedal kickback, reducing drag, and delivering a near‑silent ride. With broad driver and spacing compatibility, the GR is the most versatile hub in the Sidekick lineup.

Key Performance Features

  • Anti‑kickback drive mechanism with adjustable deadband (12°, 15°, 18°)
  • Decoupled freehub disengages during coasting for reduced drag and smoother suspension
  • Near‑silent operation for an immersive riding experience
  • Reduced chain slap and vibration for improved comfort and control
  • World Cup–proven reliability, fully serviceable and rebuildable

How Sidekick Improves Suspension

The adjustable deadband filters chain tension before it reaches the pedals, allowing the rear suspension to move freely without resistance from pedal kickback. This results in:

  • Better small‑bump sensitivity
  • More consistent suspension performance
  • Improved traction and cornering stability
  • Reduced rider fatigue on long descents

  • Driver: Microspline

  • Spokes: J‑bend
  • Ratchet Ring: 60T pusher‑driven 3‑pawl system

Why Riders Choose Sidekick GR

  • Virtually eliminates pedal kickback
  • Significantly reduced coasting drag

  • Broadest driver and spacing compatibility in the lineup

The e*thirteen Sidekick GR Rear Hub is the ultimate upgrade for riders seeking maximum suspension performance, reduced fatigue, and a near‑silent, ultra‑smooth ride.
