Evolve FS is ARC8's interpretation of an XC bike. We naturally wanted it to be light and fast on a race track. But most importantly, we wanted to bring that speed onto your trails. We were riding what is now called Down Country bikes all our lives. Until now, they were just The XC bikes upgraded with 120 mm travel forks, shorter stems, wider bars and a dropper seat post. We see this as the standard configuration of a modern XC bike, so we designed the Evolve FS for it from the beginning, with the option to go down to a 100 mm fork for racing.
We combined the lightest construction we could think of with 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.

GEOMETRY

Even if it is the lightest frame out there, the geometry is the real standout feature of the Evolve FS. It would not be out of place on an enduro bike and is a big part of its unique character.

 LIGHTWEIGHT OPTIMISATION

To achieve a frame weight of 1240 g, we invested a lot in FEA. Using Laminate Tools, we created and analyzed more than fifty different layups, something that would not have been possible doing physical prototypes.

SLIDER SUSPENSION

When designing a rear suspension, you are always faced with conflicting goals. You want your linkage to be small because it is lighter, stiffer, and saves space. But for the suspension performance, longer links would be better. Our patented slider is small, light and stiff, but it represents an infinitely long lever, creating an almost perfectly linear-progressive ratio.

ACROS HEADSET

We developed a headset with Acros that cleanly integrates into the design, with the cables disappearing below the stem.

AERO DOWN TUBE

The down tube of the Evolve FS uses an aero profile down tube. Not only is it fast against the wind, but it also collects a lot less mud in wet conditions.

TWO BOTTLE CAGES

Whether long marathons or extended bike laps on hot summer days: the Evolve FS offers enough space for two water bottles.

BSA BOTTOM BRACKET

Creak free, easy maintenance, no fit issues - all our frames come with threaded BBs.

REVERSED MAIN PIVOT

The swingarm goes into the seat tube rather than around it, creating a very stiff connection. We are using Enduro Max bearings, specifically designed for MTB full suspension frames.

DESIGNED FOR CARBON

Our frames are designed with the manufacturing process in mind from the start. Only like that we can ensure a carbon structure that can be produced with consistent high quality. While the focus in the development of carbon frames very often just lies on stiffness and weight, we also put a lot of effort into minimizing the chance of manufacturing flaws like voids, wrinkles or low compaction areas. This is absolutely critical to make carbon products not only light and stiff, but also durable.

FLATMOUNT DISC BRAKE

We are using the lighter and cleaner flatmount standard on the Evolve.

SRAM UDH

We are all for standardized parts, and Sram's UDH is just that.

FASERWRK BASLERSTAB

Combine the Evolve FS with the Faserwerk Baslerstab for even more weight savings
