Bianchi Imola w/ 105 for $550: deal?

[WindingRoad]

BTW, I have that bike and it is a great ride! Extremely responsive and feels racy, the steel kills a lot of the road buzz. I paid $500 for mine used off craigslist a couple of years ago. The 105 on that particular bike works fantastic. It works as good as my Ultegra its just a few grams heavier and not quite as fast to shift. You would only notice that if you were planning to race with it though. The only thing I want to change is the crappy crankset that came with it, surgino, weighs a ton!
