Radon Skeen 120 27.5 Frame

High performance aluminum chassis: Radon Skeen 120 27.5 Frame in petrol turbine orange

The 7005 aluminium frame impresses with its stiffness to weight scores and low density. It is equipped with a Conehead head tube for mounting tapered forks. With its lightweight carbon swingarm linkage, the frame weighs in at under 2500g. Geometry was optimised with a view to speed, comfort and controllability, making a balanced bike for long, tough tours or marathon races. All models are equipped to enable integration of adjustable seat posts. Internally routed cables lend the frame a tidy appearance.

Technologies

Adaptable X12 Hanger
We optimized our new dropout design based on the Syntace X12 through-axle system, enlarging the area of the frame where the hanger is mounted. We can now fit the longer Direct Mount hangers. Shifting precision and stiffness is therefore improved. With the new design it's also possible to swap the whole contact area of the axle with the hanger should the system be worn out.

Integrated Cable Routing
Internally routed cables offer many advantages. Cables are protected from dirt for longer life, weight is saved thanks to the absence of external housing and the bike has a clean, sleek appearance.

Integrated Post Mount
The post mount rear brake system is found on all carbon fiber frames and top aluminum full suspension models. Two bolts and the IS adpater aren’t needed anymore, and fewer parts means less weight. In this case we save 30 grams. This may not sound a lot. But there's potential to save weight in every detail.

Tapered Steerer
This steerer tube design is stiffer than a conventional straight steerer and yields a more secure ride feel even in difficult terrain. Minimal flex at the front of the frame means the greatest possible steering precision. With the larger steerer, the forks become more rigid. At the same time weight is saved due to the absence of bearing shells as the lower bearing is fully integrated into the head tube.

X12 Through Axle
In this system, a cone is used to form a play-free connection. It is only necessary to tighten the axle from one side. The position of the wheel is done by an insert in the right-hand dropout which is secured by a bolt. The main advantages of the Syntace system are quick and simple changing of the wheel, reliable position of the brake disc and higher stiffness of the rear of the bike. This allows the assembly to be made lighter than a conventional through-axle.
