Hi Greg
Yes, thank you, I am aware that b/b threading and hubs are nominally the same on English threaded items. Living in England that hasn't escaped me.
I made the mistake of not recognizing the American venacular if saying one thing and meaning something else. For which I thank all of those who have already emailed me to point this out. Clearly you guys talk in a secret language!
Perhaps it might be more appropriate to try fitting and English freewheel instead of an Italian make on an English hub. However, my offer still stands, if Paul cares to provide me with his spec, I will endeavour to supply whatever he needs with the correct English threading.
