T47/86 Bottom Bracket for Shimano Gravel
T47 is a newer bottom bracket shell design, utilizing the oversized interface of PF30 and EVO386, but with the benefit and peace of mind of a threaded interface. This bottom bracket allows you to install Shimano and other 24mm diameter thru-axle cranks into a T47 shell.
It's compatible with 86mm wide frames, and also compatible with TREK T47 85.5mm wide frames.
CeramicSpeed Bearings come installed in cups and are connected through the shell. The Gravel bottom brackets are built with CeramicSpeed Coated bearings and equipped with UFO Long Life Grease for the ultimate in durability and protection in all environments. The CeramicSpeed Coated Bearings have an additional attribute: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, lowering drag and increasing life.
Technical Data of the CeramicSpeed Coated Ceramic Bottom Bracket
T47 is an open standard designed to provide the benefits of both oversized shells and the tight fit of threading. These cups and bearings adapt the shell so it is compatible with 24mm diameter spindle cranks.
The CeramicSpeed Coated Bearings reduce drag by over 75% when compared to stock bottom brackets. Down to 0.3-0.4 watts per set. This is the result of hardened-steel races, coated with a unique non-corrosive surface finish and combined with CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition, in addition to lasting longer.ceramic
