The T47 Bottom Bracket Shimano (86mm) by Tripeak is designed to accommodate the T47 bottom bracket standard, which has gained popularity among custom bike manufacturers. T47 represents a "threaded" bottom bracket standard with an approximate outside thread diameter of 47 millimeters. Unlike the traditional BSA (Birmingham Small Arms) threaded bottom brackets, T47 cups have larger dimensions, providing enhanced compatibility with modern oversized frame designs.
T47 Bottom Bracket Standard
The T47 standard combines the threaded interface, known for its reliability, with the larger diameter found in standards like PF30 and EVO386. This results in a robust and versatile bottom bracket system suitable for a wide range of frames.
This bottom bracket is specifically designed to allow the installation of Shimano cranksets with a 24mm diameter thru-axle into frames equipped with a T47 shell. It ensures a secure and precise fit for Shimano cranks, including popular models used in road and mountain biking.
The T47 Bottom Bracket Shimano (86mm) is compatible with frames that have an 86mm wide shell designed for T47 bottom brackets. It is also compatible with TREK T47 frames with an 85.5mm shell width.
The threaded interface offers the advantage of easy installation and removal, making maintenance and service more straightforward compared to press-fit bottom brackets.
