Park Tool GPS-29
The Park Tool GPS-29 is a 28.99mm bottom bracket guide pin for DUB spindle cranks that threads into Park Tool tools to stabilize removal and installation. It suits mechanics working on modern SRAM road systems.
- The GPS-29 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 28.99 mm pin engages into the bottom bracket, bolstering the fitment of the bottom bracket tool and preventing misalignment
