I'm selling my K2 Mountain Bike. It is a 21 inch frame and is in great shape. I bought it about a year ago at Sports Authority for $450 and have ridden it maybe 20 times. I don't have any time to ride it and could use the cash. That's why I'm selling it. Just ask me and I'll email you some pictures. If you're in Atlanta doing your rotations feel free to contact me to come by and look at it.
