I'm looking at buying these Avid Elixir 5 disc brakes;

One quick question that I'm a bit confused about - My Reba forks are post mount, the ring swingarm on my Isis is IS mount. Will these fit? Do they come with the relevent adapters or do I need to buy these seperate? They are listed as IS mount but the picture shows a post mount caliper with an adapter. So what's the deal here?!

Cheers :wink:
