Chris King's DUB Bottom Bracket Fit Kit will get your DUB cranks spinning in a Threadfit 30 bottom bracket! Chris King bottom brackets utilize Fit Kits to ensure that cranks mate perfectly with their precision bearings, extend product life, and reduce the potential for noise. 

This kit is compatible with all DUB mountain fitments, as well as DUB road fitments with ThreadFit™ T47 bottom brackets.

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

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