For fans of Chris King and the latest Shimano mountain bike components, it’s almost time to celebrate. Why? Because today, Chris King officially announced that they are ramping up production to release Micro Spline compatible driveshells by the end of January.

As a quick refresher, Micro Spline is the new freehub standard from Shimano that they created to work with smaller 10 tooth cassette cogs on 12 speed cassettes. Currently, you’ll find Micro Spline cassettes in the Shimano XTR 9100, XT M8100, and SLX M7100 families, though we’re assuming we’ll see more cassettes use it in the future as well.

The roll out of Micro Spline compatible freehubs from companies other than Shimano has been a bit slow, but we’re told that they’re rapidly approving new licenses to anyone who meets the requirements for production. Which is great news for anyone looking to buy a new Chris King hub – or more importantly, anyone looking to retrofit a current ISO Boost or Superboost hub.

True to Shimano’s promise of a lighter freehub system, Chris King says that their Micro Spline driveshell uses a new bearing and axle design which has resulted in their lightest ISO hub to date.

New hubs will be offered in ISO B (Boost) and ISO DH Superboost configurations and in both stainless steel or ceramic bearings. Conversion kits will also be offered to fit all ISO B and ISO DH Superboost rear hubs. Expect the new hubs and conversion kits to start shipping on January 31st, and as usual, they’re backed by King’s Lifetime Warranty.

CONFIGURATIONS:

  • ISO B
    • 148x12mm
    • 24h, 28h, 32h
    • Stainless Steel or Ceramic bearings
  • ISO DH Superboost
    • 157x12mm
    • 28h, 32h
    • Stainless Steel or Ceramic bearings
  • Conversion Kits
    • Stainless Steel or Ceramic Bearings
    • 148x12mm or 157x12mm

      • Agreed. The Centerlock adapters from DT Swiss and Bike Ahead are some of the nicest and easiest to use ones out there. I see no disadvantage and no big deal to using one…..After seeing numerous home mechanics strip-out rotor bolts, it is one standard *ahem* that should be universal.

    • Centerlock is great! You can use any rotor you want, and they’re much easier to deal with. A single fastener, the lockring, is removed with an ubiquitous tool. I prefer centerlock hubs, but mostly use 6 bolt rotors anyways. 6 little bolts is tedious!

      • Centerlock (or IS with CL adapter) is great for travel too- I toss my lightweight Wolftooth lockring tool (with an 8mm insert for pedals on the other end) in my travel case and have no excuse not to remove the rotors when flying/shipping. Sure beats trying to straighten a bent rotor or locate missing rotor bolt on the first day of vacation.
