What is the difference between Italian threaded and BSA bottom brackets? The main difference is in how they thread into the bottom bracket shell. On BSA bottom brackets, one side is reverse (left) threaded, while both sides of an Italian standard bottom bracket shell are regularly (right) threaded. The shell size is also different, with BSA bottom brackets using a 1.375” (34.92mm) diameter shell and Italian BB’s using a 36mm shell. The width of the bottom bracket shell is also different; BSA bottom brackets are usually 68mm or 73mm wide, while Italian threaded bottom brackets come in at 70mm wide.
Both standards use a 24 TPI pitch thread.
