I have owned my Giant Revolt 1 for almost a year, now. Finally decided to join the discussion after reading all the other posts. In the past year, I have put 1,728 miles on my Revolt, and I love it! I ride a mixture of really bad pavement (l live in N.E. Oklahoma where road maintenance is almost un-heard of) and gravel, as well as some totally off road, MTB type stuff thrown in for good measure. The revolt has become my all arounder. I have commutted by bike, 18 miles one way trip, all day explored, and rode for just the pure pleasure with it.
You can see plenty of pictures on my blog at

The Revolt is ultra-comfortable, and is a beast. The upright position makes it very comfortable for an all day ride. I put Clement MSO's, 40mm width tires on it and there is room for more width if desired. I can tell you that it is super-stable in some very rough downhill runs that I have done. It is NOT a speed demon, for sure. I have a Defy road bike that I use on pavement when I feel a need for speed. The Revolt is my favorite, though, as I can ride it anywhere I desire. Have taken it places where I usually ride my MTB, but stay out of the super deep mud with it. Also, have put a rear rack on it and have packed my fly rod down to some local ponds for fishing, on occasion. This bike is not going to win you any speed contests, but you will find it is more than capable of going the distance on any endurance type of ride. I have ordered a new, 2015 Giant TCX advanced pro 2, and plan on using it for anything requiring a little more speed than the Revolt can produce. I have never felt unstable, no matter what type of gravel conditions I have rode, on the Revolt. In my opinion, it is an excellent gravel ride, and I know that I will put many more miles on it before I am finished. Also, the mechanical disc brakes are top-notch, and haven't let me down. The geometry of this bike, and how it is set-up, soak-up a lot of the punches that gravel can throw your way. First thing, though, was to ditch the stock tires in favor of the MSO's. Made a huge difference in how the bike felt and handled.
