I have a Bianchi cross bike that is my everything bike atm. I use it primarily for commuting but also does service as a road bike and if I'm in the mood I'll even go and surprise all the mountain bikers at the local course with it. It's smooth enough there that I can smile to myself as I keep up with a 5 inch travel yeti whilst I'm cruising along in the drops.
I've been trying out various road bikes recently because the cross bike is quite an old lumbering thing which weighs I think about 14kg with what it has on it atm and isn't the stiffest of bikes around. I can definitely feel the quicker steering on the road bikes I'm trying . Looking forward to getting a second bike so I can change the cross bike to a 1x9/10 and have it as a proper winter commuter/cross bike.
