Certainly faster on rough roads plus on descents. The safety margin is higher. I can tell while on those fast and twisty corners I usually do near my house. I am not on the ragged edge anymore. For me it isn't about being faster on the downhills in general...it is about being safer and enjoying the corners. The improved traction and the ability to brake quickly and effectively (ever seen a deer pop out when carving at 35/40 MPH?) even though I generally am trying to go slower in these sections. The comfort is really really nice. With a larger contact patch, a bigger safety margin, and a little more compliance, it just makes cycling more enjoyable for me.
