Chris King Releases Micro Spline Support for R45D Hubs

January 3, 2024

Portland, OR /OUTDOOR SPORTSWIRE/ – Chris King has announced the release of new Micro Spline drivers for their market-leading R45D hubs, available January 1st from all Chris King retailers.

Shimano’s Micro Spline technology improves engagement in the freehub, with 23 closely spaced splines driving the cassette. Coupled with Chris King’s own R45D hubs, which take a similar approach to consistent engagement, the new Micro Spline drivers produce an unparalleled ride experience.

“The name of the game in hubs is compatibility,” said King Sales Manager Greg Hudson. “We aim to support as many drivetrain and cassette combinations as we can. Micro Spline is a key addition to our offering, especially as 12-speed drivetrains proliferate and the 10 tooth cogs that come along necessitate Micro Spline compatibility.”

The new drivers are compatible with all King Centerlock and 6-bolt (Gen 2) R45D hubs, which already support Shimano HG EV along with SRAM XDR systems. King’s Micro Spline drivers will be available in silver and black.

“Micro Spline seamlessly integrates with our R45D hubs,” Hudson continued. “With 45 points of simultaneous engagement, our hubs provide unparalleled power transfer and efficiency, ensuring a smooth ride both on and off-road. This synergy, especially beneficial for gravel and all-road enthusiasts, highlights the durability and superior performance that define the Chris King R45D hub experience.”

King will offer the Micro Spline drivers as a conversion kit for existing hubs, adding it to the wide variety of conversions possible.
