Chris King Boost 6-Bolt 148x12 rear hubs are designed as precision mountain tools. One-piece solid axles to provide a stiff hub that will help your suspension perform better and drive every watt of power into the dirt. To thwart mud, water, and contaminants as you power through rough trails, Boost 6-Bolt hubs have heavy-duty bearing seals, and a threaded driveshell seal ring

Patented RingDrive with 72-points of simultaneous-engagement will get your power to the ground fast, provide unmatched engagement, and give you that legendary Chris King angry-bee sound
Legendary made-in-house bearings
Steel bearings have heat-treated, surgical grade steel races that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races
Quality and speed of bearings is what sets King apart from the competition and they are what you will feel and notice on every single ride
As bearing tracks burnish they get faster with age and all King's hubs and bearings are fully serviceable for years upon years of demanding use
Responsibly lightweight
Canted flanges for stronger wheel builds
Easily serviceable with a 2.5mm hex and pick or pen knife
Completely re-buildable with ISO Hub Service Tool (sold separately)
Brake/Compatibility: 6-Bolt disc
Hub Drilling: choose; 28 hole, or 32 hole
Rear Axle: 12x148mm "Boost" thru axle
Cassette/Driver: Shimano Micro Spline
Spoke Interface: J-Bend
Engineered, manufactured and assembled in Portland, Oregon USA
