CHRIS KING - THREADFIT T47 30i BOTTOM BRACKET

We build bearings, so we build bottom brackets. T47 is a standard we helped 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.

It’s a silky smooth, long-lasting bottom bracket built around 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.

You want this bottom bracket because it offers super low drag. You want this bottom bracket because it can be opened, cleaned and repacked for years of faithful service. You want this bottom bracket because you don’t want to think an awful lot about your bottom bracket.
