Brake problems are from the past with the patented nokon konkavex - system. This is due to the ingenious technology: flexible articulations and a pressure-resistant outer shell ensure absolute precision when braking. And this for the long run.
The brake cable was treated in a special PTFE soak. By this treatment, the surface stain-resistant and friction is reduced. 1800mm long.
