Bb t47 shimano black

Description

The T47 is a newer bottom bracket shell design, utilizing the oversized interface of the PF30 and EVO386, but with the added benefit and peace of mind of a threaded connection. This bottom bracket allows you to install Shimano and other 24mm diameter thru-axle cranks in a T47 shell. It is compatible with 86mm wide frames. There are two versions: standard and coated bearings. The CeramicSpeed ​​bearings come pre-installed in cups and are connected through the shell. Both versions feature super-round ceramic balls and hardened steel races. The CeramicSpeed ​​coated bearings have an additional feature: a 3-micron thick metallic layer over the races. This addition makes the races harder and smoother, reducing drag and increasing lifespan.
