Hi. I have a co worker who wants to sell an older mountain bike. I don't know much about moutain bike stuff. It has Shimano XT components, steel frame and front shock. It is in good shape and he is asking $170. I am not looking for something with a full suspension etc so I think this might work. I also know Keith Bontrager from trek stuff. Would this be worth the money provided it fits and everything is working?
