Anti-Drop Splined Bottom-Bracket Sleeve Tool Carbon Steel Bike Bottom-Bracket Sleeve Tool Knurled Bike Part Threaded

This bike part is a bike bottom-bracket sleeve tool designed as a splined bottom-bracket sleeve tool for compatible bottom-bracket systems, giving you a custom-designed bottom bracket tool for service and removal work. Built as a 20-tooth bottom-bracket tool, it is intended for 20-tooth outer caps, making it suitable for matching bike bottom-bracket sleeve applications where a secure fit matters. The tool combines carbon steel and S136 steel with a compact metal body in black and silver, featuring a knurled black threaded top section, a central threaded shaft, and a silver hexagonal lower body with a toothed outer band. An anti-drop screw structure and spring section help keep the tool aligned during use, supporting steadier engagement and reducing the chance of slipping or dislodging while working on the bottom bracket. Measuring about 11 x 3.9 x 3.9 cm and weighing around 210 g, this bike bottom-bracket sleeve tool offers a compact, manageable form that is easy to handle in a workshop or repair kit.
