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

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 EZO bearings, TPX hub shell bearings, and nickel-plated pawls, representing the highest performance tier of e*thirteen’s revolutionary hub technology.

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 eliminating pedal kickback. This allows your suspension to track more effectively over square-edged hits and reduces rider fatigue over long, technical descents.

This model is configured with a 28-hole shell and a Shimano Microspline driver, designed for Boost 148mm spacing. The hub provides a wide stance for improved wheel stiffness and utilizes 6-bolt disc mounts and J-bend spoke compatibility for easy servicing. Despite the advanced internal mechanism, the Sidekick Pro maintains a competitive weight for a heavy-duty hub.

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. When every millisecond of suspension performance and traction matters, the Sidekick Pro is the definitive choice for a connected, compliant ride.
