This Bike Changed Cycling Forever, Here's Why

Carbon fibre dominates the pro peloton today, but its journey to the top began with a radical vision nearly 40 years ago. We explore the history of the Kestrel 4000 and the "Godfather of Carbon," Brent Trimble, who bypassed the "black aluminium" era to create the first mass-produced carbon monocoque frame. Finally, we put a vintage Kestrel KM40 to the test against a modern Orbea Orca Aero to see just how much progress we’ve really made in four decades.
