Here is a short list from the last couple of years...
2- Bridgestone RB-2's
1- Bridgestone RB-1's
1- Bridgestone XO-1
1- Pinarello Surprise
3- Centurion Lemans RS + Dave Scott's
2- Fuji S-10's
2- Bianchi's-Campione
I can't remember how many Treks! Steel only. Usually make a little on these. Brand name is the draw maybe?
I don't make much on these, as they often go to friend's looking for bikes. Just for fun, mostly. I save up any extra money and it pays for my Italian bike obsession. God help me once I start with custom bikes!
