Chris King Threadfit T47 30X bottom bracket

Chris King builds bearings, so builds bottom brackets. T47 is a standard help develop, an answer to the imprecise and often loud press fit bottom brackets that appeared on the market a few years ago. T47 offers the benefits of larger bottom bracket shells, mainly frame stiffness, with the upsides of traditional, threaded bottom brackets, precision and quietness. All the bottom brackets come with King’s legendary, angular-contact bearings, either steel or ceramic. These are the best bearings in the industry, and actually get faster over time, as their contact surfaces wear.
