Not a potion, but still effective.
New crank and an older frame? No problem. First, pick up Chris King's ingenious new Threadfit 24 Bottom Bracket. Now, if you are running road bike cranks with a tapered 22-24mm spindle, such as certain SRAM, Bontrager, Truvativ, or Zinn cranks, and your bike has a 68mm-wide BB shell, you're going to want the Chris King Bottom Bracket Conversion Kit #9. 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.

I have an older Chris King Bottom Bracket (maybe 4 or 5 years old) currently running a Shimano Ultegra crank. Would the #9 conversion kit allow me to run a SRAM crank with this BB? Thanks.
