Chris King Boost Rear Hub

With 72 points of contact, the hub engages almost instantly when you start pedaling. This minimizes the 'dead zone' in your pedal stroke, which is particularly helpful for technical climbing or navigating tricky, slow-speed trail features.

Chris King manufactures their own bearings in-house, and they are designed to be serviced rather than replaced. Unlike many standard bearings that degrade over time, these are built to break in and actually run smoother the more you ride them.

This specific model features a Shimano Micro Spline freehub body. You will need to ensure your cassette is compatible with the Micro Spline standard before purchasing.

The hub is designed to be fully serviceable, and Chris King provides detailed guides for maintenance. While it requires specific tools and a bit of mechanical patience, it is a straightforward process that significantly extends the lifespan of the hub compared to non-serviceable alternatives.

No, this hub is specifically engineered for the Boost 148mm x 12mm thru-axle standard. It will not fit frames with traditional 142mm or 135mm rear spacing.

The canted flanges are angled to better align with the spoke path to the rim. This reduces stress on the spokes and creates a stiffer, more durable wheel build that handles lateral forces better than standard hub designs.
