Chris King ThreadFit™ T47A 30 Bottom Bracket

Made to fit T47 BB-Right shells with 30mm spindles, the Chris King ThreadFit^TM T47A 30 Bottom Bracket combines the best qualities of press fit and threaded bottom brackets to offer precision, quietness and efficient energy transfer, all in one long-lasting product.

Engineered, manufactured and assembled in Portland, Oregon, this bottom bracket is built to the T47 standard, which Chris King helped to create, using the brand's renowned bearings that get faster with age. It therefore offers the benefits of larger BB shells, particularly frame stiffness, with the refined, smooth action of a traditional bottom bracket.

As well as being exceptionally low drag, this bottom bracket, in common with all produced by Chris King, is easy to service to restore optimum functionality. Fit Kit 3, 5, 1 or 2 is required for use, depending on the type of cranks you have, and must be purchased separately here.
