Looking for some advice - I would like to put a disc brake on these 2001 marzocchi bombers . It appears to have some kind of double tab mount but on closer inspection I’m not sure these even have a thread!? Can you put a disc on these forks? If yes, what kind of adapter do I need? Cheers!
It's a normal I.S. (International Standard) mount. The bolts thread into the adapter. Most brake makers do adapters for various sized rotors for this type of mount.
