I have 6 grave bikes at the moment, and this is my favorite right now. It's 4lbs heavier than my carbon gravel bikes, but doesn't feel like it. I'm also not enough of an e pert to know every single nuanced difference between all the frame materials, and I'm sure the front fork helps, but this thing just glides. I love the ride feel.
Also, and I can't believe I'm saying this..........I really like the 2x drivetrain. That 50 tooth outer ring is really nice at times.
