Freewheels , English ,ISO,Italian thread ?

[latman]

Just how tight is an ISO threaded freewheel (as the bay seller claims) on an Italian thread ?? (written on the Campagnolo shell)

ps it fits on an English thread very well

The ISO freewheel will go on about 4 threads then jam solid, when you eventually get the freewheel off about 4 threads on the hub will be wrecked.....

That's what I've done in the past IIRC.

not compatible, sure Sheldon has something on this, loose non drive bb cups are a useful check for iso I believe as same size ?

its a nice pair of Campag Nuovo Tipo hubs and I have not screwed it on with anything more than easy hand force for fear of damaging the alloy threads

I guess if it's on all the way, you might as well leave it there. If not, take Shauns advice and don't try to force it on.

so it goes all the way home with gentle hand force? if so then it's an ISO freewheel on ISO threads....... An ISO frewheel simply does not go down easily all the way on italian threads.

I think TGR had this problem last year.

I seem to remember he was doing English/Italian or visa versa. But who knows. I've got loads of freewheels with no thread type stamp on them. :roll:

 

[torqueless]

My memory tells me that TGR's thread-destroying block was French thread onto an ISO hub?
IMO if you can get a block all the way on with no resistance then it should be OK. If you do meet any resistance, then go no further- unscrew the block and find out why...

English / Italian may be more of an issue than ISO as sits between them, guess rather depends on how worn everything is

no it only went on easily for a few threads before binding , so i aborted ...
