Product Description
The BTS-1 is a precision tool system designed to ensure that threaded bottom bracket shells are properly aligned and faced. The precisely crafted two-piece tap handle engages through the bottom bracket shell, ensuring that both sides are aligned with the shell and with each other. The included English threading taps accurately check and repair the alignment of the threads in the shell. After tapping, the taps serve as guides to keep the included facing cutter perfectly square with the bottom bracket axis for cleaning the faces of the bottom bracket shell.
