The MTB Racer. Considering today's extreme XC-tracks challenges, the Racing Ralph has been reworked completely. As a result there is a very fast and versatile XC-profile, especially developed for the rear wheel. There are many gripping edges in the Profile's middle section for super traktion und exzellent acceleration. Parallel it shows extraordinary rolling properties and is extremly soft. The Tubeless Easy version with ADDIX Speed (red) means velocity, stability and durability.
