The e*thirteen Sidekick GR Rear MTB Hub features a unique anti-kickback drive mechanism with adjustable deadband, providing smooth suspension performance, reduced fatigue, and nearly silent operation for an unparalleled riding experience. Designed and tested with the world's top teams and racers over multiple seasons, the Sidekick GR offers the broadest driver compatibility in the lineup across Boost 148mm and 157mm (DH, Super Boost) spacing. The 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, resulting in an impeccably smooth ride over the roughest terrain, improved traction, and reduced fatigue. 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 3-pawl system provides silent operation and reduced drag by remaining disengaged unless pedaling Available in Boost 148x12mm, Super Boost 157x12mm, 148mm DH, and 157mm DH spacing XD, HG, Microspline, Mini-HG, and 7-speed integrated cassette driver compatibility 6-Bolt disc mount, 28h and 32h J-bend spoke configurations E-MTB compatible Proven on the World Cup, fully serviceable and rebuildable, backed by a lifetime bearing warranty and a 10-year warranty on all other parts Pair with the Sidekick Pro Front MTB Hub to complete the build.
