ARC8 ht 2

Built for Speed Evolve - XC the modern way.

Over the last few years, we saw an evolution in XC racing. Courses became more technical, getting through challenging features efficiently now can make the difference between winning and losing. The Evolve was designed exactly for that style of racing.
It is light and stiff, so you can power up the climbs. The compliance lets you carry your momentum over bumpy parts of the course. If it you still have competitors on your wheel by the time you reach the descend, it is time to drop the hammer: with a slack head angle and long reach, this bikes is absolutely flying when the trail points down.

Tech Specs:

Mud Shedding Design

No mud collecting, shelf-like surface here. Mud will follow the smooth backside of the seat tube until it gets ejected to the ground, saving you a lot of weight by the end of a wet race.

ICH Cockpit

Mountainbikes deserve nice and clean cockpits too. Already a proven solution on our road bikes, we now bring the ICH cockpit to the world of MTBs. The cables for the rear derailleur, rear brake and dropper post enter the stem below the handlebar and run internally from there.

Aerodynamic Down Tube

The down tube has a similar aerodynamic, but efficient shape as our Escapee frame. Not only does it slice through the air with much less resistance, it also offers much less surface for mud to stick on it than the rectangular shape found on so many frames.

Dropper Post Ready

On the demanding courses of today's XC racing, a dropper post often is the smarter choice. Because dropper posts can be built much more reliable at a bigger diameter, we went for a 30.9 mm seat tube.

Damping

Even a hardtail can have shock absorption and damping capabilities. This got even more important with the growing popularity of dropper seat posts. A clever mix of materials and dropped seat stays make sure you stay controlled and driving the pace over rough ground.

Progressive Geometry

While geometries evolve towards more capability in technical terrain, many hardtails still have head tube angles and stem lengths close to road bikes. Why would we limit the descending capabilities of our bike like that? Keep in mind that on a hardtail, in riding situation the head tube angle gets even steeper because there is only sag in the front. Our geometry is designed around a 70 mm stem length, compensated by a long reach and accompanied by a reasonable head tube angle, letting you attack no matter what the gradient is.
