Really? Most mountain bikers I know are a little nutty I think Marin isn't more popular just because they aren't more popular. I don't even know where there is a Marin dealer in my area. But I have Trek, Specialized, Kona, Gary Fisher, and Giant dealers around every corner. Oranges and Moots are great bikes too from what I've heard, but I've only seen people riding them once (both in the same ride actually) and I've never seen either in any store.
