It looks interesting, but very overbuilt. Whats the reason for the top and down tubes to be parallel? I'd imagine that would only make the frame weaker because there looks to be almost no triangulation between them. The integrated booster/frame brace looks really interesting, a nice lightweight way of stiffening up the rear. The dropouts are way too big though, and they look really long aswell, surely there's no need for such legnth, the wheel can only move as far as a set of 4 bolt mounts after all? Tyre clearance looks good, I wonder if you could get a 2.7" Maxxis in there? The weight sounds OK aswell, althought I'm guessing it could drop a fair bit off that. Good effort, not bad for a first prototype.
