Good thread. In 2010 I was set to get a new road bike. First one since 1986 other than the frame I made myself in 2000. Had the chance to go to Specialized for a dealer event in Morgan Hill. Of course, we road bikes! The ones I was interested in were the S Works Roubaix and Tarmac.
After riding both about 20 miles each it occurred to me they don't offer anything better than my current crop of vintage bikes. I ain't fast and these things didn't help me go faster, climb better or feel more comfortable.
Picked up a titanium frame from Habanero in 2012, put my NR group on it and have put on thousands of great, scratch and rust free miles.
