If anyone has any information about these hubs, it would be more then welcome. They came with Campagnolo 10s, and Ambrosio Excellence rims.
I need to find a new freehub body, and make a new axle, thanks to the incompetence of my lbs.
After spending some time I managed to find someone who can make a new titanium axle, but the problem is that I have no idea where to find a replacement cassette. The guy who sold me the bike told me it was Miche, but after contacting them, they said they did not produce such a hub.
I have a feeling its an Italian maker since the bike was bought in Italy. And except for the tires, everything was Italian branded.

Here is the link to another Italian forum with pictures of the hub, since you need 10 posts to get the permission for uploading pictures.

Sorry, I've never seen that hub before. But it looks like it has a two-pawl freehub with one mangled spring. Since you didn't photograph the left side of the hub or the outside of the freehub body, I can't tell whether it uses loose-ball bearings or cartridge bearings. Whatever. Also missing from the photo are the axle, bearings, endcaps or locknuts, and the sleeve-nut combination that attaches the freehub body to the axle. It's highly doubtful anyone is making parts for this. Don't be too hard on your lbs. Bike shops are not machine shops, and I doubt a machinist could reverse-engineer this hub without more clues, anyway. Good luck.

Don't recognize the exact hub either, but that giant spring clip retaining the drive side spokes is a very Mavic thing.

It's a long shot but maybe if you post the make, model, and year of the bike. Maybe the hub was OEM and there is a catalog with it listed?

This is a bit of a guess...But could these be Campy HPW hubs, and the free hub was changed out?






There's a freehub that's similar called Hope RS4 Hope RS4 2-pawl body – Campagnolo – Stealth Wheels The springs look similar. Maybe this is a older version of it?

I googled the bit of text legible on the spokes and came up with Ambrosio for those too. If the rims are Ambrosio as well, maybe they made the whole wheel set?

Ambrosio's main product was rims, as far back as at least the 1970s. Until carbon, their Nemesis alloy tubular rim was standard issue for cobbled classics and cyclocross racing. Complete boutique wheels were probably added to the lineup around the late 1990s or early 2000s.

Looks like an earlier version of an Ambrosio Alpina hub. https://www.oldbici.it/product/ambros...lset-clincher/

There appears to be a newer version with external spoke holes a la Mavic Ksyrium SL. https://www.ebay.com/itm/30392486986....c101197.m1850
