People, people, people....
Check the ss/fixie forum under the Anyone wanna trade___? They have a formula, and it works very well- put what you have, state what you would like to trade for, or what you're looking for, or what you want for what you've got. Otherwise, people may think that what you've got does not match what they have. You could miss out on a good trade.
Try it again... most of you guys have it right, but there are some people in here just listing what they have... I would have no idea what you're looking for, and I wouldn't know if what I have is sufficient for what you listed.
Good luck!
