Chris King Boost 6-Bolt 148x12 rear hubs are designed as precision mountain tools. We use 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.
Our bearings, available in steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races. The quality and speed of our bearings is what sets us apart from the competition and they are what you will feel and notice on every single ride. As Chris King bearing tracks burnish they get faster with age and all our hubs and bearings are fully serviceable for years upon years of demanding use.
The patented Chris King 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.

WHY WE MAKE THIS
It's our job to make the best riding hubs in the industry, and 142mm x 12mm rear hubs are THE standard for road disc and gravel bikes, so we poured our hearts and souls, not to mention an awful lot of engineering, into this hub. We think it's the best all-around disc hub on the market.
WHY YOU WANT IT
R45 Centerlock hubs combine a lightweight hub body, our legendary made-in-house bearings, and Centerlock compatibility. The result rolls better, lasts longer, sounds cooler, and looks way more handsome than anything else out there.
On top of all that, the 45 points of simultaneous engagement in this hub improve power transfer and traction thanks to our patented RingDrive system.
Our bearings, both steel and ceramic, have heat-treated, surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of our bearings is what you will feel (and hear) on every ride. As Chris King bearing tracks burnish they get actually get faster. A little bit of regular love (i.e. service) will keep this hub rolling for years upon years of demanding use.
All Chris King rear hubs come with that signature, angry-bee sound.

Zipp's ZM2 hubset delivers dependable precision performance to the gnarliest trail. This German-engineered hubset features 12 pawls and 132 points of engagement for a quicker response. The hub's improved seal design means better durability on rough terrain. The genius of the ZM2 hub is how we achieved quicker engagement.
This hub system works with 12 pawls, in 4 groups of 3, on a 33-tooth ratchet ring. The 33 teeth make the ring strong with pickup that's reliable and consistent.
The 4 groups of 3 pawls are staggered, meaning there are always 3 pawls engaging at any time, which boosts durability. The ZM2 also has higher load transmission capability. The hub is capable of being used on electric mountain bikes.
- Engineered in Germany with better seal design for improved durability
- 132 points of engagement
- Designed with 12 pawls (4 groups of 3) for quick engagement
- Strong ratchet ring maximizes load capacity
- Compatible with e-mountain bikes
- Spoke Count: 32h

In designing an upgraded hubset for our pro-proven Firecrest wheel lineup, we turned to our engineering colleagues at SRAM's development center in Schweinfurt, Germany. The result is the ZR1 hubsets for disc wheels. This hubset features better seal design for improved durability and quicker response with 66 points of engagement. Our engineers spent more than two years developing the ZR1. Proving the durability of the hubset included more than 58,500km of test riding, part of 3,222 hours of total testing. The ZR1 features key technology from Zipp's Cognition hubs. The seal design is the same as the Cognition, with a large dust cap at the base of the driver body and better bearing seals for more protection. The bearing size also is the same as the Cognition, although the Cognition uses a premium bearing. The six pawls are offset to work in two groups of three pawls. There are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement. The driver body is designed so pawls stay in place for disassembly to make service convenient. Zipp hubs are designed to use J-bend spokes, the most popular type of spokes today. J-Bend, widely available, are easier to replace.
- Better sealing, increasing durability over previous hub model
- Quick engagement for a responsive ride
- Lightweight
- Same bearing size as premium-level Cognition hub
- e-bike certified
- Disc brake hub with Center Lock rotor interface. The lock ring is included
