You're pumped to try out your new ride, and feel the squeak-free benefits of your beefy T47 bottom bracket, but don't forget to pair your Chris King ThreadFit T47 24x bottom bracket with the proper conversion kit before tossing in your crank. If you're rolling with a 24mm tapered crank spindle, snag the Chris King BB Conversion Kit #26. This stepped kit is ideal for cranks with stepped spindles, like SRAM GXP mountain and Truvativ, adding the pieces you'll need for a snug and supportive fit for superior power on the bike. It's designed to take a 24mm spindle down to 22mm in the center for a secure fit, and secure into a 73mm bottom bracket shell.
