Chris King Gen 4 Hubs Get Frequent Parts, Swapping Driveshells Now Easier & Cheaper
Chris King has on a regular basis been about making most likely probably the most precise elements – it’s correct there throughout the title. Their hubs are artworks, with their patented RingDrive system buzzing away as you coast. Nonetheless that RingDrive precision received right here at a price, notably a further difficult service course of and costly driveshell replacements.
Chris King had already phased out their needle-bearing design of the RingDrive system in 2019. Transferring from that to a twin-bearing system lowered drag by larger than 20% and made for a system that was lighter and less complicated to manufacture. The issue was that adapting the current hub design to the current twin-bearing system required a variety of axle and inside driver physique variations.
Now with the Gen 4 hubs, that each one changes.
“Earlier iterations of our hubs needed to steadiness compatibility with evolving exterior utilized sciences, similar to the SRAM and Shimano drive strategies, with our patented internals and bearings. With these core strategies having stabilized, it gave us an opportunity to rethink what was occurring inside our hubs, and so we took the chance to simplify points for our riders and streamline manufacturing.
For Gen 4 we undertook a holistic progress course of for each of the three hub merchandise Improve CenterLock/6-Bolt, R45D, and R45, collapsing the specs proper right into a design that allows for a typical axle and inside elements. In earlier generations, we chased specs that led us to utterly totally different bearing sizes, and so forth. Gen 4’s widespread elements have allowed us to streamline manufacturing, and due to this, helped us reduce hub prices AND the worth of the small elements long-term riders will want for hub service and upgrades.”

Notably, Chris King components out that “this isn’t a performance-based evolution.” Principally, the hubs now use widespread elements which enable King to provide drive system conversion kits for merely $80 (for hubs which could be already reworked to or supplied as Gen 4). Consider that to their earlier conversion kits which have been as a lot as $380 in 2023. Larger however, the Gen 4 system is backward acceptable with earlier King hubs, so that you presumably can convert your present hub to Gen 4 – though these conversion kits are costlier. “Transferring forward, Gen 4 R45D and Improve 6-Bolt conversion kits are priced at $275, which contains the axle, adjusting clamp, bearings, and driveshell. Equally, Improve CenterLock conversion kits are priced at $250, inclusive of the axle, bearings, and driveshell.”
On the time of writing, prices for model new Gen 4 hubs weren’t accessible, though everyone knows that driveshell conversion kits for model new hubs must run $80 since you solely need to differ out the driveshell. Chris King says that Gen 4 hubs are literally supply and are being constructed into their full wheels.
Specific enhancements with Gen 4 embrace:
- Mannequin new driver/axle system
- Improved compatibility/ease of adjusting Driveshell varieties
- Lower-priced conversion kits
- Larger XDR particular person experience with threaded Driveshell end cap
- Easier assembly and disassembly (no axle wedge)
- Simpler preload adjustment (no spacer spring to compress)
- Further versatility as a consequence of widespread axle and inside elements
- Further cross-compatibility as a consequence of widespread bearing sizes
- Backward compatibility with earlier generations of King hubs
- Gen 4 R45D hubs benefit from an updated adjusting clamp that allows for disc eradicating with out the need to remove the adjusting clamp.
