SunTour Vx
Can anyone say what reach the SunTour Vx rear dérailleur has.
I have 42/52 in front and (6-speed) 12, 13, 16, 21, 26, 31 on the freewheel.
Now donīt suggest me to try it to know if it might work. I do not have all parts to run a practical test. Otherwise it would be the obvious solution
I also wonder if I can take for granted that a freewheel marked with "REGINA CORSA 2 ITALY 78" has italian threads? Is it made in '78 and therefore the number "78"?
Thanks for any input in these matters.

Death fork? Naaaah!!
The Sun Tour literature I've seen seem to indicate that the Vx will run with a 30t, anyway. They don't specify a long cage until 32t. FWIW, I run a V-luxe with a 28t with no troubles.
I also would guess that your Regina freewheel is standard thread. The one that came off my '73 Atala was, as are the three others I have in the freewheel bucket.

I have an other Regina freewheel, 5-speed, marked with "REGINA CORSA 2 ITALY 79" and it was sold to me as italian threded freewheel on ebay. Should not the freewheel be marked with the kind of threading it has?

ISO - 3 grooves on back
English - 1 groove or F.I. stamped on back
French - 2 grooves or F.F. stamped on back
Italian - no grooves or stamping on back
ISO is marginally different than English in diameter (0.005") but completely interchangeable, so consider ISO and English to be standard.

I've read somewhere that if you use a english threaded freewheel on an italian treaded hub you should not go back to italian threaded freewheel because the threads on the hub gets a little damage and there will be a risk of stripping the threads on the hub if you fit a italian threaded freewheel after the english treaded. Is this just in theory or just if you are a strong rider that apply much force to the threads?

Better to be on the safe side and run 30 T as the largest sprocket then

It is generally safe to mix the Italian and English threads on hubs and freewheels for cyclists of medium strength and weight, however, once you mixed the threads, you should not switch back and forth.
The above rules of thumb are not just theory. I received a stripped English hub earlier this year, after the owner went back to English freewheel, because he couldn't find an Italian threaded replacement for the one he had worn out.
