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 BB allows you to install Quarq and SRAM 24/22mm spindled cranks into a T47 frame.
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 Coated 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.
