I just bought one and did 33ish miles on it yesterday. I'm a pretty s*** rider, I have asthma and suck at hills and into the wind, and my other bike is a road bike on 23 tires...
What it does well:
The geometry is comfortable for three hours (I'm 6' tall and bought the Medium)
The gearing combo climbs well
It handled dirt and gravel as well as I expected
Its pretty light (I don't have a number for you)
Disc Brakes are good
What I don't like:
The pedals were seized on. I had to cut them off then use a torque wrench. Might be the LBS' fault or the factory's.
The seat is probably fine for racing but sucks for long rides (go figure)
The Front Derailer doesn't like going small chainring to big chainring. Might just be an adjustment/break in issue. If I followed rule #90 it wouldn't be an issue
