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, Superboost) 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, Superboost 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 5-year warranty

Pair with the Sidekick Pro Front MTB Hub to complete the build.

Great for a side sleeper. Firm enough that it doesn’t collapse but soft and cool

Love this pillow!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I sleep on my side and this pillow is great! I also enjoy the cooling aspect. I forgot my pillow at a hotel and had another one ordered before I got home.

Life-Changing Comfort – Best Pillow Ever!
Size: Queen Size: 27.6"L x 15.7"W Medium, Color: White
I can’t say enough good things about the Releep Memory Foam Pillow—it’s an absolute game-changer! From the very first night, I noticed a huge improvement in my sleep quality and neck support. One of the best features is the dual-sided design—a firm side for extra support and a cooling soft side that feels like sleeping on a cloud. I love being able to switch between them depending on how I’m feeling. The memory foam provides just the right balance of support and comfort, cradling my neck perfectly and keeping my spine aligned. No more tossing and turning or waking up with a stiff neck! The cooling side is a dream! It actually stays cool throughout the night, which is a lifesaver for hot sleepers like me. I used to constantly flip my pillow looking for a cool spot, but not anymore. If you suffer from neck pain, tension, or just want a better night’s sleep, this pillow is 100% worth it. I’ve tried so many pillows over the years, and nothing comes close to this one. I wake up feeling refreshed, pain-free, and ready to take on the day. Highly, HIGHLY recommend!

Nothing like I hoped
Size: Standard Size: 23.6"L x 15.7"W soft, Color: White
This is a piece of foam in a "cooling" pillowcase, which is not cooling and the foam goes flat. No support and no cooling. Very disappointed that you cannot trust reviews for true product information. The good part is you can return which I did.
