A friend has an old Specialized Stumpjumber FS bike. It seems to be in decent shape, no cracks or rust. Deraileurs need some work and the chain rings are beat up pretty bad. Wheels are not true and need some work also. I am trying to determine how old it is. It has a threaded stem and direct pull cantiliever brakes. Components are all Deore LX. Any way to identify the age, or any ideas? Also, approx value. It needs some series cleanup and such, and I he is not sure of the value....I would love to get it cheap, but I want to be fair.
