What is this worth? I know nothing about tour bikes other that this is the real deal, rides down my rougher roads like a dream. Owner must have taken care of this bike or had a recent service as the bearing are smooth from the Stronglight B-Henault (A-9?)headset to the Maillard Helico Matic rear hub. RD Deore XT may not be stock but all else looks like it, even the Selle San Marco leather saddle shows it for the 1985 620 on the vintage trek site. Has cast Trek lugs on the 531CS frame, measured more like 22" but I think Trek called it a 22 1/2", Zefal HPX4, Shimano FC-6206 170mm and brakes and levers (dry hoods), Sacks Huret FD and DT shifters, Normandy front hub and Matrix Titan T rims. I have the original receipt, 8-17-85 and the owners manual. 27x 1 1/4" tires look new. Lots of paint scratches, no dents and thankfully no attempts to touch up the matalic blue paint.
