Hi
I am selling my Trek S4 Dual Sport Bicycle. It is on a 21" frame and has disk brakes (back and front) and shock absorbers on the front tires. You can lock out the shock absorbers as needed depending on the conditions. This makes this a great bike if you want something that is fast and agile on the road and then can be ridden in the back country mountain trails.
I haven't used it in a year and have decided to sell it and use my road bicycle instead. I don't have the pedals on it presently but can easily add those if you want them. There is a small amount of rust on the chain but otherwise the bike is in good condition.
