Chris King bottom brackets utilize Fit Kits to ensure that cranks mate perfectly with our precision bearings, extend product life, and reduce the potential for noise. Fit Kits will also allow you to use one bottom bracket with a wide array of cranks, if you happen to change you cranks in the future.
For DUB cranks we have two fit kits to choose from, Fit Kit #1 DUB A and Fit Kit #2 DUB B.
For use with ThreadFit 30, ThreadFit T47 30i, ThreadFit T47 30x

For DUB Super Boost + cranks you will need one additional spindle spacer kit; PBB081.
