So happy with this purchase. I researched gravel bikes, test rode the Trek Checkpoint, Giant, and this bike is superior to the rest. Geometry is very comfortable, yet it can be driven like a road bike. Very and fast and light, due to carbon frame. So easy to carry up stairs, over obstacles. I chose this model to save $700 off the comp carbon: tires, wheels and carbon frame are excellent. Only benefit to Comp Carbon is the FutureShock 2.0 vs. 1.5 on Sport Carbon. FutureShock 1.5 is excellent, absorbing bumps and smoothing out the ride for your wrists and forearms. 2.0 is a little better because you can adjust dampening. FutureShock is essential to a good gravel ride. My only upgrade thought is to get a FS2.0 fork next year. Also, I've rode on gravel, asphalt, gnarly grass/dirt with small roots - it handles it all feeling light, quick and stable.
