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 your 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.

Fit Kit #1 DUB A
Covers all DUB mountain fitments, as well as DUB road fitments with ThreadFit™ T47 bottom brackets.
