I am riding the 2010-2011 S1, i do normally 50-80km ride everyday with one or two 100km+ training ride a week, can see for yourself in my strava below.
Its really an awesome bike, sure it does not dampen the vibrations much like my previous bikes eg. velocite magnus or pinarello galileo. But the negative road feedback is still manageable. Ride more with it and you will get used to it.
Its really an excellent bike, with great handling characteristic and fast acceleration.
