the Post Punk is really nice, and you can just use adapters to go to ISO. In fact, I have yet to use it on a post mount. Back when you had to buy front and rear ISO fixtures, that was a lot more money. I was trying to figure out how to use it with direct mount for forks, but it seems somewhat pointless, unfortunately. The adapter for direct mount rear is somewhat ungainly. Haven't seen direct mount fittings for forks that I like anyway.
