Shimano brake adapters are fuggin expensive. Anybody have any luck using anything else? I just ordered a boxxer, and I'm running saint brakes with saint 203mm rotors. I don't really care if its mcgyvered, I'm pretty sure I've used avid adapters in the past and had them work just fine. Thoughts?

I used a Hope 8" boxxer adapter with my Saints with no problems. Be sure that if you use Avid adapters that you keep the conical washers with it no matter which brakes you are using.

I'm kind of curious about that as well, I'm about to order a 35mm boxxer and I've got more hayes/avid boxxer adapters than I can count. Hopefully I don't need to buy even more adapters.
35mm Boxxer uses standard post mount, as opposed to the 32mm boxxer which is, "Boxxer mount".

standard 6" post mount, for whatever reason. You will need another adapter to run 8" disk brakes, or I'm doing it wrong.

I've run Magura disk adapters (louise QM et al, not gustav) with undoubted success for two years. Rear 203/IS, front 203/Boxxer, then front 203/PM standard. They cost like 7 bucks, come with bolts, and already have red loctite on the bolts. What more could you axe for? Maybe longer bolts for the sunday's wicked long IS mount...

Yep. Pretty sure it's only Fox that have the 8" post mount, no? Or have Marzocchi started on that game too?

I'm running that exact set up (well, it's a Formula rotor) with an Avid adapter, no problems.

I think fox does something awful like using 7" PM, so you need a 6-7" adapter (20mm spacing).

Marjokey uses direct post mount, I think.

Why RS doesn't use direct PM is beyond me. Why add weight to the system when you can just cast the posts 40mm higher?

This is wrong.

You do not need the tri-align washers with other brakes even on Avid adapters. Avid brakes use a higher off-set mounting point to allow for proper spacing with the tri-align washers. Using them with say Hayes or Shimano will lift the caliper above the rotor a fair amount.

This. Like I said, I'm running an Avid adapter on my Saints and do not have any washers.
