Campagnolo Hub Axle Diameters
Can anyone tell me if Grand Sport and Nuovo Tipo hub axles are the same diameter? I know they are different lengths.

If I recall correctly, all Campagnolo axles are 10mm x 26TPI, with the exception of the solid axle Nuovo Tipo, which is 9.5mm x 26TPI.

Actually, I'm not sure they are. I assume they would be as the GS rear hub measures 87mm across, and was made at a time when rear drop outs were 110mm apart whereas the NT hub is 89.6mm across and was made when drop outs were 120mm apart.
I have a front NT hub and the axle measures 8.8mm across and I have what I think is a front GS axle (sold to me as such) which measures 9mm acoss. The known rear NT axle I have is 9.9mm across.

What vintage Gran Sport? Through the 70s and 80s, Gran Sport hubs were Tipo hubs. My edition of Sutherland's (4th) doesn't have information on the 1950s Gran Sport hubs, and the Campy catalogs of that period don't specify it.

The diameter must be measured at the thicker threaded part because on my 70's Record rear axle seems to be only 9mm at the smooth center part.
I want to get a longer axle at bikepro.com but their listing it at 9mm. Something is wrong as they list the front at 9mm also. We all know the front axle is smaller. I may phone them and ask because they do not have email contact!
At the page below, the Campi Record rear axle is:
9MM x 1 x 130MM
Is the 1 meaning 1 thread per mm ?

Just cut to length, not difficult at all. I use these all the time.

My two pairs of Gran Sport hubs, steel center sections and accept quick releases are exchangeable with later Record parts. I would have to take one apart to reference the front hub ball bearing diameter.

LOL still a very spendy part for what it is. I guess you cann't get a soft cone at DQ for 5 cents anymore either! York Peppermint Patties are over a $1! Just 5 years ago I refused to even consider buying one for $.50!

Also, how much steep climbing using a very small chainring, all will affect the service interval before an axle failure occurs.
At 225lb with an 8-speed freewheel, this setup would be relatively fragile regardless of the frame's axle spacing.
The frame's inside spacing will affect the potential strength of the wheel/rim, but not the axle (assuming here that the axle spacers are set for minimum axle overhang using whatever freewheel has been chosen).

Wheels manufacturing axles do not have a slot, making them much stronger than original.
