e*thirteen Sidekick Pro Rear Hub - 28H, Boost 148mm, XD Driver

The Sidekick Pro Anti-Kickback Rear MTB Hub is built for trail, all-mountain, enduro, and E-MTB riders who want the full Sidekick experience with upgraded internals. This Pro version features premium EZO driver bearings, TPX hub shell bearings, and nickel-plated pawls for reduced friction and improved surface hardness over the long term. Finished in a dual black and sterling silver anodized coating, it is designed for riders who demand the best in technical performance.

Like every Sidekick hub, the Pro fully decouples the drivetrain from the suspension during coasting. The pusher-activated magnetic pawl mechanism retracts completely when you stop pedaling, giving you genuine near-zero drag and near-silent operation. By eliminating pedal kickback, your suspension is free to move through its travel without fighting chain tension, resulting in superior traction and a smoother ride through rough, square-edged terrain.

This configuration features a 28-hole drilling, Boost 148mm spacing, and an SRAM XD Driver. The tool-free deadband is trailside-adjustable to 9°, 13°, or 18°, allowing you to choose between quick climbing engagement and maximum anti-kickback performance for descents. At just 300g, it features a 17mm alloy axle and is ASTM 5 rated for the most aggressive riding.

Fully E-MTB compatible and built to withstand high-torque loads, the Sidekick Pro is backed by a 10-year warranty with lifetime bearing coverage. This hub is the definitive choice for a connected, compliant, and silent ride on the world's most technical trails.
