not 1981

but 4EL081 as ma(r)king for a nice interpret-able side reference

Coincidentally in that year however Charlie made the first two bikes for somebody else than himself. A set of two similar yet very different Aluminum frames for the Don and Steve Cook (A livelong advocate of dropbars fully in the sense of Cunningham even taking the concept to full suspension prototype bikes of modern Mountainbike brands made in American).

Die BIKE schreibt:
Das Specialized Stumpjumper war 1981 das erste Serien-Mountainbiker der Welt

WIkipedia stellt richtig:
The first mass production mountain bike was the Specialized Stumpjumper, first produced in 1981

Needless to say, the welds are better than on 90% of Cunninghams
and the heattreatment was something they also made sure was spot on...
Anyway the credit still goes to Charlies Apllied technical department for all the conversations he had with those who were inspired to follow him be that KLEIN, ABM or anybody else at the time...
