1979 Schwinn Spitfire 5

The Spitfire 5 was an attempt by Schwinn to ride the mountain bike wave without spending too much money.  They added a drum brake, heavy duty spokes and 5 speeds to the regular cantilever frame to make a pseudo mountain bike.    The Shimano Positron shifting system used a solid wire cable to push and pull the derailleur which has a series of detents that lined up with the gears.  This was a very early attempt at indexed shifting.  As the "Klunker" craze grew, this same bike was sold with a Klunker 5 name in certain markets.  This bike was made in late 1979 which may make it a 1980 model year bike.
