History

Historical Context

Trek’s 1995 introduction of the carbon-fiber 5500—cycling’s first mass-produced carbon frame—triggered a decade of weight-focused innovation, leading Shimano to release a $1,200 105 groupset in 1996 and Specialized’s Allez in 1997. The technology lineage continued when Trek supplied frames to the Leopard Trek WorldTeam, founded in 2011, and today’s Domane SLR sheds 305 g, echoing that early ultralight drive.
