I went and looked at them again today and I was mistaken. They are both CAAD 8's, but the difference between the two were one was a 16 speed and the other was an 18 speed. I think the higher priced one was a 2010 CAAD 8 with Tiagra components. Will probably go with the more expensive one. I think it was around $870. Is that a good price? Do your arms get used to bending over or does that mean the bike doesn't fit properly?
