Item # CKG000I

Convert to the best.

The good folks at Chris King are known for taking their time when developing new components, and the Oregon-built press fit bottom brackets are no exception. But we’re inclined to think that the PF30 bottom brackets have been worth the wait. They require adapters for cranksets with a spindle smaller than 30mm, so if you want the finest possible way to affix your GXP 24mm crankset to your PF30-equipped frame, the Chris King BB Conversion Kit #4 is precisely what you’re looking for.

This conversion kit adapts a Chris King PF30 bottom bracket to use with a GXP standard crankset, for a 68mm PF30 frame. If your frame has a 73mm PF30 shell, you’ll need the Conversion Kit #3 instead. Please note that the Chris King PF30 bottom bracket is sold separately.

The Chris King BB Conversion Kit #4 is available in the color Black, and one size.

This is for a bb30 to gxp conversion kit right?

Umm yes and no. This is meant to be used for Press Fit 30 bottom brackets. While they are very close in design, this is only meant to work for Chris Kings PF30 bottom brackets, and will not convert other bottom brackets. Email me directly at gmcbride@backcountry.com and I can set you up with the correct item for your needs.
