Front hub nut size

[Thotos]

I think the front hub nut on the Trevi (possibly all Betas) is 34mm but can someone confirm this or put me right if I'm wrong?

I thought it was 36 but i couldn't be 100% sure

36mm on my 1981 spider.

Thanks guys, 36mm it is then. I know it's not 32 (got one of those) and not 38 (got one of those too) so must be 34 or 36. I thought someone told me it was 34 but probably my memory fails me again, old age you know...

NB if you get a single hex impact socket the walls are so thick it won't fit through the hole in the disk so you have to take the disk off first.

If you got a bi -hex version you might just be able to undo the nut with the disk in place.
