Earlier this year, I acquired my new old steed to replace my roughly 15 year old steel bike (frame is ~20years old, 105 group only 15 years).
I was pondering a Trek Madone 5.2, but the wife gave me much schtick about spending so much on a bike, so I found something I knew would still get me out there, but wasn't so costly (and - perhaps because it was my first ride ever with brifters - I felt mildly uncomfortable with the movement of the Ultegra brake lever, whereas this Campagnolo system feels a lot more solid).
