A few key elements on pricing.

Location... some markets are better than others.

Tubing... I notice what looks like it could be a tubing decal, but I don't recognize it from the angle of the pic. Chromoly vs 1020 etc makes a difference...

Size... Certain sizes are in the range where more cyclists would be interested and generally go for a little more. I personally wonder if a patient person can actually make more money on an odd ball size.
