Paul Anders (Sup at Crowder State Park) has a older rigid Trek Antelope 850 for sale.
The color is called Grape so I take it is purple and it is a x small frame so it might be good for a small adult or middle school aged child.
The bike has some used "hybrid" tires on it for fast rolling. Paul also has the original knobbies that have not hardly been ridden.
He is asking $100 for the bike and can be reached evenings at:
