Hey,

If I recall correctly, the older Marzocchi Z.1s with the dual disc mounts were not IS but a Formula-specific mount. Right? Or no?

If so, is there an adapter to run an IS disc up front?

Thanks.

51 mm = IS

Yup...the tabs do not have IS spacing. They're something like 48mm if I recall correctly. Hayes does make an adapter (part #98-14590) but I imagine it might be hard to track down at this point. Plus I think with that adapter you have to use the old school calipers designed for the old Manitou post mount spacing of 68mm.

Alternatively I seem to remember Hope making a C2 caliper that mounted on those tabs directly but I can't remember what number it is.

I had to have a machinist friend of mine customer make an adaptor because I couldnt find one anywhere. wasnt a huge deal

that fork looks familiar.

Those are pre-IS mounts.....

it doesnt get much more non standar than the right side mount

Two brake mounts? on a SC? might as well put a couple 10" rotors on there and some 6 piston calipers and we'll and call it a day.

Nah...

I don't suppose you have a sketch/dimensions of what that adapter looked like?

Thanks,

Yep. I had/have one of these forks. It's a '97 model (possibly late '96). The mounts were meant for old Formula brakes and Hope did make a C2 caliper half that worked - I had one of those too; sold when I unloaded my collection of Hope stuff... . I don't recall Formula offering a hub with disc mounts on both sides. The fork had mounts on both sides because for a time, Formula offered calipers for either side if you wanted to run your levers moto-style. The idea didn't catch on...

Hayes had adapters for those. but would put your caliper out to a 8" only. i had a local machinist make me one aswell.

goodluck with that...
