This complete set of five guide pins adds stability and security to the bottom bracket removal and installation process. Each pin included in the GPS-1 is sized for one of the most common thru axle hub or bottom bracket spindle standards. 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 pin engages into the bottom bracket or hub, bolstering the fitment of the tool and preventing misalignment.
