Smoking deal! Around here that 520 if it is a 700c wheel would fectch $225 and that STI Cannondale would be $300+ depending on the model (what model is it I cant read the lable). I suspect that was either a Divorce drop off or the owner has passed and the family didn't know their worth.
Hay in the future take your pictures from the drive side...we like to see the cranks and derailleurs.
