My friends bike had 6", the one I'm looking at only has 4. The one that I rode didn't seem to bob at all and that was going hard on the road. I would have thought the longer travel model would be the one that would bob more. I have to try one on the dirt soon.

So it may be a little fragile? That was one of my concerns.

also looking closer at the Dawg, it is effectively a single pivot too.
