Park Tool GPS-30
The Park Tool GPS-30 is a 30 mm guide pin for bottom bracket and hub alignment during installation. Precision-minded mechanics use this pin with Park Tool BB tools to prevent tool misalignment.
- The GPS-30 adds stability and security to the bottom bracket removal and installation process
- The guide pin simply threads into any of the thirteen Park Tool bottom bracket tools which feature integrated threads (see Product Compatibility for full list). A 5 mm hex fitting is integrated into the threaded end for secure and easy installation and removal
- Once installed, the extra-long 30 mm pin engages into the bottom bracket, bolstering the fitment of the bottom bracket tool and preventing misalignment
