What your frame deserves.
That steel frame you're fixing up either has or will very likely pass the test of time with flying colors. Giving it the best bottom bracket in the business should be a no-brainer. First, pick up Chris King's ingenious new ThreadFit 24 Bottom Bracket. Now, if you are running road bike cranks with a 24mm spindle, such as certain Shimano, FSA, or Rotor cranks, and your bike has a 68mm-wide BB shell, you're going to want the Chris King Bottom Bracket Conversion Kit #8. The Kit slips onto the crank's spindle and then into the Chris King ThreadFit 24 Bottom Bracket on your bike. If you have any more questions about which CK conversion kit to use, please let us know and we'll help you out.
