Well guys i have no self control and ended up snagging this second Stumpjumper. Unsure of the years, but I'm thinking the silver is an '83, The Blue one is my daily ride. I always felt my bike was too big for me so I got the second bike hoping it would be a better fit. Anyways I decided to do a side by side comparison.

The blue Stumpjumper isn't stock. I replaced the derailleurs with something a little better IMO. Also switched the wheels to utilize a 6 speed freewheel over 5.

Anyways heres an album with some differences if anyone cares.
