oster_oops: My bad!It's a 203mm Hope floating rotor. Just running a 203mm RS adaptor and two small (like 1mm) spacers. Took the fork for a ride today after hooking up the front brake, lowering the crowns on the stanchions and playing with the pressures. It's my first experience owning an RS fork (long time Dorado and Marz owner) and I'm quite happy with it.
