2024 Ceramic Speed T47/86 Inboard 30mm Bottom Bracket - Black
Ceramic Speed
The T47 threaded bottom bracket shell utilizes an oversized interface of PF30 and EVO386, but with the benefit and peace of mind of a threaded interface. T47/86 places the bearings within the width of the frame and is compatible with 85,5mm wide Trek frames, as well as standard 86mm wide T47 Inboard frame designs. This bottom bracket allows you to install Campagnolo and other 25mm diameter thru-axle cranks into a T47 shell.
There are 2 versions: Standard and Coated Bearings. CeramicSpeed Bearings come installed in cups and are connected through the shell. Both have super round CeramicSpeed Balls and hardened-steel races. 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.
