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.
