CHRIS KING - THREADFIT T47 24i 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.
Install with Theadfit T47I Tool only.
REQUIRES A KING CONVERSION KIT TO COMPLETE INSTALLATION
All of our bottom bracket offerings will use an appropriate Conversion Kit specific to the brand and model of crankset to be used. Our Conversion Kits are made to account for crank manufacturers' machining tolerances and ensure they mate perfectly with our precision bearings, extending product life, and reduce the potential for noise.
