1977-78 Exxon Graftek G-1

Introduced in 1976, the Exxon Graftek G-1 combined aluminum tubes wrapped in graphite. The tubes were joined together using epoxy resin to 17-4 investment cast stainless steel lugs. The frameset was tested (by L.P. Burke of Livermore, CA) and compared to steel framesets was found to have increased torsional and flexural rigidities, by 9% and 11%, respectively. Initially, the G-1 was produced with a chromed Reynolds 531 steel fork that was replaced in late 1977, early 1978, by a steel/graphite wrapped version.
