I just received an older road bike from my friend. Its a Trek 1000. It hasn't been ridden in who know how long. I just got it and know it needs a tune up. Shifting needs work, wheels look pretty true, brakes squeal, but otherwise i'm not a good enough expert to know about the bearings or such.
How much will a tune up cost for it? Should i get a complete overhaul, or just the basic adjustments?
