10 year old Cannondale road bike - bicycles - by owner - bike sale - craigslist
Like new cannondale 21 speed road bike. Derailleur will be repaired by the morning after this post. Rides great, smooth shifting, everything works except the Derailleur which is original and will be...
I'm very wary of this one. In my area, but there are some egregious things about the post that I kind of take as red flags:
1) "Like New" condition, when it's clearly stated that the rear derailleur "is broken, but will be fixed by the day after this posts." I can't call a bike with what looks like a broken derailleur hanger (and rather askew brifters) "like new."
2) The bike frame is not carbon fiber. Even in the lousy pictures posted, the welds at the head tube are clearly visible. I mean, aluminum isn't awful, but it's not carbon fiber. The fork is, I am certain.
3) No mention of the model name/number.
4) $400 is a lot for a broken "10 year old" bike, though it probably is a fraction of the original price of the bike.
I will probably reach out to the owner, if for nothing else than to ask what size it is and what the serial number is.
