Compared to my aluminum mtn bike? I describe it as night and day

Seriously though I tested at least 15 bikes before getting my new Ti bike and of those 80% were carbon, hard finding Ti around here. While the carbon was stiffer the Ti was still very stiff and out of the gate and on climbs, full tilt, I don't feel the flex and I'm a clyde. I love the ride and don't notice the road vibration etc even compared to my mtn bike with front shock. I'm not exactly aiming for potholes though.
