alpenchallenge AC01 mountainroad series
The original
The alpenchallenge offers a unique geometry, a rather more upright seated position and the optimum combination of stability, light weight and agility. Gear and brake cable housing that is perfectly integrated into the shape of the frame guarantees a neat and tidy look. The alpenchallenge is available in two alternative wheel sizes: the 700 C wheelset guarantees smooth running while the 26 ” wheelset delivers maneuverability and high rates of acceleration.
