My favorite bike yet and an excellent example of well-ridden vintage Trek. The 640 was made by the Trek bicycle company just one year: 1983. New, the bike featured full Campy components (which were stripped off of this prior to my purchase and replaced with a Shimano set less the front derailleur). Marketed as a sport/multi-purpose bicycle aka sport tourer, the bike featured the same frame/geometry as the Trek 600, 620 and 630 in 1983 (chainstays on this bike were 3cm shorter than the 720 of the same year 44cm vs. 47cm.) The 640 was constructed with Reynolds 531c double-butted tubing This example has been outfitted with an 18-speed transmission (Shimano Biopace elliptical triple chainwheels up front), Mavic MA40 rims, Odyssey BMX pedals with original NYC-made Hold Fast foot straps, Profile bullhorn bars and a vintage Fujita Belt leather saddle.
