Item #PG-001A: This bottom bracket shell is machined from 1 5/8" x .150" wall 3-2.5 titanium tubing. The outside diameter is machine finished to size, 1 9/16". The width is 68.5 mm, supplied 0.5 mm oversize to allow for clean up after welding. The threads are 1.370"-24, right and left hand, and thread length is 0.50". The left hand thread is identified by a radial groove on the face of the shell. The minor diameter of the thread is 1.330"/1.340" and is relieved on the inside diameter to 1.385"/1.395".

All of our threaded bottom bracket shells are 1.37" x 24 threads per inch and are right and left threaded (also known as British Standard, ISO/English or BSA), making them compatible with all modern threaded bottom bracket spindles.
