TRIPEAK - Bottom Bracket  - T47 (Threaded) - For Factor Frames, Shimano Hollowtech II - 77.5mm shell width, Ceramic Bearings

T47 is a new bottom bracket standard that is becoming increasingly popular with custom bike manufacturers. The “T” stands for “threaded” and the “47” is the approximate outside thread diameter of the cup, in millimeters. T47 bottom bracket cups are not compatible with the much smaller BSA threaded BB shells.

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 bottom bracket allows you to install Shimano and other 24mm diameter thru-axle cranks into a T47 shell.

It's compatible with 77.5mm wide Factor frames.

Advantages of Ceramic Bearing

• A well-made ceramic bearing will roll faster, saving you energy and allowing faster cruising speeds compared to an equivalent steel bearing.
• Ceramic bearings are more corrosion-resistant, harder, and last longer in everyday use.
• Ceramic balls have an exceptional ability to retain their “true” spherical shape under load. This creates the conditions for ceramic-equipped components to have an exceptionally long and smooth running life.
• A good quality ceramic bearing can easily last five times longer than steel and they don’t rust.
