I have a Marzocchi Z1 Dual, and wanted to use it with an Avid 185mm (7") disk brake.

I searched the avid site and they say they don't make any adapter for this situation, is there any way I can use this combo? (hayes adapter or other)

Thanks!

PS - For those that do not recall the Z1 Dual model, I'm including a pic.

A Hayes adaptor is supposed to be the only way to make it work. Personally I use several thin washers behind the adaptor to move the caliper out to where it's supposed to be. I know others are doing this as well.

I've got a Z150 with 20mm and a 7" Avid and bolted on fine, think I added on spacer between the mount and caliper

To my knowledge, the spacing on that fork should be the same as any other Marz fork using IS with a 20mm axle... So, it should be the same bolting a brake to that fork or to a 2005 Z1...

I can't tell from the pic, but are the IS tabs bolted onto the lower with 2 6mm bolts? If it is, you can get an adapter that bolts directly to the fork. A hayes should be identical to an avid. I've interchanged them before.

Hayes makes an adaptor that is specific to the marzocchi 20mm IS mount, for some reason the distance from the rotor to the disc tab along the axis of the axle is different for a QR and 20mm on marzocchi forks (So much for IS.) Avid and hayes adaptors are interchangeable for any other fork but you need the marzocchi specific 20mm adaptor if you want it to be sparkling clean looking. Like I said earlier, you can just use washers behind the adaptor.

Thanks all for the replies.

So let me see if I got this right... there are 2 ways to pull this off:

1 - using spacers between the calliper and the adapter to push the calliper further away from the axle. How many spacers are we talking here? 10mm of spacers? Wouldn't this cause problems like squealing, etc?

2 - getting a Hayes adapter. Which adapter is this?

PS - Regarding the brake mounts on my fork, they are not bolted to the lowers, they form a single cnc'ed piece with the left dropout.

Contact Chad at redbarnbicycles.com in Montana. He can order you what you need.

hardware store, $1, and you should be good. Just space the caliper, didn't cause squealing for me.

A Hayes adapter won't work, they don't make a 7" adapter. Avid, however, does. You will need to space the adapter over 5mm as thru-axle forks have 110 hub spacing and QR forks (which the IS adapters are designed around) have 100mm spacing.

^ He speaks the truth.
It can be done, quite easily, with the right adapter and a few spacers. You can either space out a 20mm 6" adapter, or a QR 7" adapter.
BTW, Z1 Duals rule the fork world, my Mr T (same fork) is still kicking on, and I don't plan on ever selling it.
