Skip the guesswork.
Gotta big rig you need to set up with a 100mm threaded BB system? No problem. First, pick up Chris King's ingenious new ThreadFit 24 Bottom Bracket. Now, if you are running fat bike or DH cranks with a tapered 22-24mm spindle, such as certain SRAM, Bontrager, Truvativ, or Zinn cranks, you're going to want the Chris King Bottom Bracket Conversion Kit #17. 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.
