New innovations for not-new tech.
So your frame relies on a tried-and-true 73mm threaded bottom bracket. Awesome. Here's what we'd recommend. First, pick up Chris King's ingenious new ThreadFit 24 Bottom Bracket. Now, if you are running mountain bike cranks with a 24mm spindle, such as certain Shimano, FSA, Race Face, Rotor, or Surly, you're going to want Chris King Bottom Bracket Conversion Kit #12. 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.
