Chris King Precision Components has streamlined hub ownership and maintenance with a new Gen 4 hub line that uses universalized drivers and axles. This is not a performance-based evolution. King’s in-house signature bearings and proprietary RingDrive system remain, but these new Gen 4 hubs make service and upgrades more effortless and less expensive. All this is done to lower the overall cost of ownership and increase the useful life of each hub. Check out more below.
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, which were priced at $380 in 2023. Gen 4 R45D and Boost 6-Bolt conversion kits are priced at $275, including the axle, adjusting clamp, bearings, and driveshell. Similarly, Boost CenterLock conversion kits are priced at $250, including the axle, bearings, and driveshell.
Specs:
- Brand new driver/axle system
- Improved compatibility/ease of changing Driveshell types
- Lower-priced conversion kits
- Better XDR user experience with threaded Driveshell end cap
- Easier assembly and disassembly (no axle wedge)
- Simpler preload adjustment (no spacer spring to compress)
- More versatility due to universal axle and internal parts
- More cross-compatibility due to common bearing sizes
- Backward compatibility with previous generations of King hubs
- Gen 4 R45D hubs utilize an updated adjusting clamp that allows for disc removal without the need to remove the adjusting clamp.
