Chris King has announced a switchover to a new hub system dubbed the Gen 4, which features new universalized drivers and axles that make service and upgrades easier and less expensive.
The evolution from the previous hub designs to the new Gen 4 system marks a leap forward in performance and serviceability. The previous generation featured the legendary RingDrive system coupled with a needle-bearing design, which was phased out in 2019. Although effective, it was complex to manufacture, heavier and exhibited 20% more drag compared to what was to follow. The twin-bearing system notably reduced drag; however, this design necessitated multiple axle and internal driver body variations. With the introduction of their Gen 4 hubs, CKPC streamlined the approach, offering universal compatibility and enhanced efficiency without compromising on their hallmark precision and durability.
“Previous iterations of our hubs needed to balance compatibility with evolving external technologies, like the SRAM and Shimano drive systems, with our patented internals and bearings,” explains Chris King Sales Manager Greg Hudson. “With those core systems having stabilized, it allowed us to rethink what was going on inside our hubs, and so we took the chance to simplify things for our riders and streamline manufacturing.
Specific Improvements with the Gen 4 include:
Hudson continues, “For Gen 4 we undertook a holistic development process for each of the three hub products Boost CenterLock/6-Bolt, R45D, and R45, collapsing the specs into a design that allows for a universal axle and internal parts. In previous generations, we chased specs that led us to different bearing sizes, etc. Gen 4’s universal parts have allowed us to streamline manufacturing, and as a result, helped us reduce hub prices AND the cost of the small parts long-term riders will want for hub service and upgrades.”
Once outfitted with the Gen 4 system, transitioning to different drive systems will cost just $80. This represents a significant reduction compared to our previous conversion kits priced at $380 in 2023. Moving forward, Gen 4 R45D and Boost 6-Bolt conversion kits are priced at $275, which includes the axle, adjusting clamp, bearings, and driveshell. Similarly, Boost CenterLock conversion kits are priced at $250, inclusive of the axle, bearings, and driveshell.
The introduction of Gen 4 hubs underscores Chris King’s commitment to sustainability by extending hub lifecycles and minimizing long-term ownership costs.
The Gen 4 hubs are available now, along with built-in wheel options as well.
