The Evolve FS is ARC8's interpretation of an XC bike. They naturally wanted it to be light and fast on a race track. But most importantly, arc8 wanted to bring that speed onto your trails.

The crew at ARC8 have been riding 'downcountry' bikes all their lives. Until now, they were just XC bikes upgraded with 120 mm travel forks, shorter stems, wider bars and a dropper seat post. ARC8 consider this as the standard configuration of a modern XC bike, so they designed the Evolve FS for it from the beginning, with the option to go down to a 100 mm fork for racing.

ARC8 combined the lightest construction they could think of with a radical geometry and an extremely efficient suspension. It makes you fly up the climb before diving into the descent full of confidence. And where your ride would end on another bike, you go up the next mountain.

The ideal bike no matter whether you are at the starting line of a race, racking up KOMs and kilometers of single trail, or just on a short and intense evening ride.
