My opinion - a fixed seatpost might not be the best call for a dirt jumper.

I know a lot of dirt jumpers who wouldn't want a bike that light. Some people like the stability and momentum that a heavier bike provides. But then, when I say some, that means that there are also some, apparently like John Cowan, who just want it light and strong. I'd tend to guess that the fixed seat post is like on a carbon road bike, where it can be cut down to desired length, but obviously never raised. Though I suppose that you could make a custom post to wedge inside the carbon.

it looks good. but how much does it weigh? the link says the frame will weigh in under 5lbs so my guess is a 22-24lbs bike. thats crazy my bmx weighs 24! my Dirt jumper weighs 27.5 and i feel alot more stable on it then i do my bmx when on trails.
