Yah, my bike weighs about 17.4lbs (less with road tires/wheels). It is insanely fun. The biggest difference is in out of the saddle acceleration. At a steady 150-200watts, it doesn't really make a difference. But this thing pops when I ask it to accelerate. Its a big reason I got the bike. Most gravel bikes are a bit laconic. For comparison, I tested it against a 28lb steel Specialized. Took about 4 strong pedal strokes to get up to speed on the light bike, took about 6 to get up to speed on the Specialized - but boy was that specialized comfortable for an all day ride. Its good to have options.
