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.

• Fit Kit #1 DUB A is going to cover all DUB mountain fitments, as well as DUB road fitments with ThreadFit T47 bottom brackets.

For use with ThreadFit 30, ThreadFit T47 30i, ThreadFit T47 30x 68mm, 73mm, 73mm SB , 86.5mm, 92mm, and 92mm SB BB shells.

Common Cranks: DUB 28.99mm spindle.

For DUB mountain cranks there are a few extra fitments notes to be aware of. If you have a 68mm BB shell you will need two 2.5mm Cup Spacers; for BSA or for T47.
