BIKE Magazine Tire Test 04/2008 - "Schwalbe’s Racing Ralph sets the benchmark. The brand-new Tubeless variant achieves the lowest ever value of 19,8 Watts, measured by BIKE, with even better durability in comparison to its predecessor."
The perfect racer. Profile, compound, carcass. In the third generation of the Racing Ralph everything is designed for speed. In the 29" variant the special arrangement of the blocks and their elongation have been adapted to the longer footprint. Performance advantages of the large wheels are optimally improved.
