I had the Factory Racing version for about six months. I bought it used from a guy who managed a small chain of bike stores. He barely rode it. Problem I ended up having was that the fit was too long for me. (I was mistakenly led to believe by a former fitter that i was a 54)
rode the bike a number of times on the road. Solid, great bike, well engineered and smooth.
I had the DA Di2 Version.
I sold it (for what i paid for it) for two reasons. One, i couldn't make the fit work and two, I need a bike I can travel with easily in the henhouse, fork on this bike is not an easily removed item.
