Park Tool Bottom Bracket Facing Set # BFS-1

The Bottom Bracket Facing Set is designed to be a complete self-contained facing set, combining top quality precision parts with ease of use. Simply install the threaded inserts using the facer handle, then insert the facing tool through the guides and install the tension spring and speed nut. After applying a liberal amount of cutting oil, the BFS-1 easily cuts the shell material, giving you a clean, faced surface. Now you're ready to install the bottom bracket.
