Mavic D321 is what I use.
I wouldn’t really put ‘lightness’ ahead of ‘all mountain’.
today I was out on some soggy trails, on the way home, got hooked out of a berm missing the bridge over the stream by a good 2ft and fell about 6ft (felt like much more) into the stream landing surprisingly cleanly on the other side.
If I’d really put some effort in I could have ridden away from my landing position in the stream. Instead of the bike breaking, or me breaking, I laughed so hard I hadn’t noticed I was now knee deep in freezing water. Only damage was seatpost was slightly twisted around.
This is what ‘AM’ is about to me, having a bike thats capable of going up, handles nicely, and isn’t so light you have to worry about things breaking when you have little off’s, instead you get to laugh hysterically while standing knee deep in freezing water in a gully. Awesome.
