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 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.
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.
Bottom Bracket tool for installation: BBT-47.
