Bottom Bracket Tool Length: 330mm Weight: 321g Material: Steel Bottom bracket tool developed from the requests of Keirin racers! The silver plate helps hold the lock ring in proper position and improves work efficiency. BBLT6 (Bottom Bracket Lock Ring Tool) is for professional use to adjust BB lock rings used for NJS. Generally, aluminum lock rings are only about 3.5 mm thick, and their protrusions can easily be damaged if the tool slips. BBLT6 has a silver plate that assists work, keeping the bottom bracket parallel to the tool and preventing offset. The three-layer handle is about 8 mm thick, and each edge of the plate is rounded for a more comfortable grip. The straight handle profile allows direct torque application for more accurate work. There is also a hook hole on the side of the handle. Six protrusions designed to fit NJS BBs (Shimano, Sugino, Hatta) and Campagnolo lock rings.
