These precision machined bottom brackets are a long lasting, freely spinning and competitively priced alternative to other options. The cups are CNC’d out of 7075 T6 Aluminum and the bearings feature high-grade 6805 stainless steel balls. These bottom brackets are a great replacement for use with 24mm spindle cranksets, like Shimano’s Hollowtech II crankset.
The T47 External bearing cups can be used on either a 68 or 73mm threaded frame while the Internal version is used with an 85.5mm width frame.
