Is 34.8x24F stamped into the cups?

The standard for "English" threaded bottom brackets is 1.370" x 24 TPI which is approximately 34.8mm.

The later ISO BB standard is 1.375" x 24 TPI which converts to 34.925mm.

The .13mm or .005" difference isn't very significant especially considering how crudely some BBs are threaded. So this bottom bracket should work fine in any English or ISO threaded frame
