One of our original tools for working on vintage bottom bracket sets. Removes even the toughest seized-in bottom bracket fixed cup. Makes installs and overhauls very fast. The latest version uses a hardened steel threaded insert to attach to the female threaded spindles, but when removed with a 4 mm Allen wrench, it exposes a 10 mm thread which will fit on stud type bottom bracket spindles. The latest version now uses a one-piece “Billet” aluminum body.
