Jerry,
The Trek 660 would have come with the following (as per Trek catalogue) Campy Nuovo Record derailleurs, levers, crankset, and Botom Bracket. SR SP-12 Pedals, Modolo Speedy brakes and levers, SR world custom bar and SR Aerox stem, Maillard helicomatic hubs, helicomatic 13-24 6 speed freewheel. Matrix Strada rims panaracer tiresand Avocet R1 saddle on SR Laprade seat post. also SR toe clips, Christophe straps and Blackurn Bottle cage. My thought? Try it, you might be very surprized by the ride, those old treks were quite the bikes, and nothing like todays plastic and aluminium models.
