• Just checked this. The old Bottom bracket tightens up clockwise on both sides, so that's Italian threaded, yes? I had thought when I took the old BB out I had unscrewed both sides anti clockwise, but assumed I just got in a muddle and remembered wrong as I was told it's a British Built frame-maybe it is is not what it purports to be, just tried a 27.2 seatpost and that doesn't seem to want to fit either...

  • Yup, French thread is 35 x 1mm, bsa is 1.370/1.375” x 24tpi so that’d account for the loose fit.
