Park Tool, GPS-1, Bottom Bracket Tool, Kit

The Park Tool GPS-1 is a complete five-piece guide pin set that adds stability and security during bottom bracket removal and installation. Each pin is sized for one of the most common thru-axle hub or bottom bracket spindle standards and threads into any of thirteen compatible Park Tool bottom bracket tools with integrated threads. A 5mm hex fitting on the threaded end allows secure, easy installation and removal, and the extra-long pin (61mm usable length) helps prevent tool misalignment.
