Thanks to its perfect combination of speed and grip, the Schwalbe Racing Ralph ADDIX MTB tire inspires the best in its riders. Featuring an off-center tread pattern, the Racing Ralph rolls fast and delivers reliable traction. Large side knobs allow mud to easily be shed, yet the tire still corners aggressively and reliably, even in wet, loose mud. This open tread design enables aggressive, explosive riding without losing grip. Inside the tire, Schwalbe's SnakeSkin protection provides added durability, fighting off puctures or slashes from trail debris, extending the tire's life in the process.

The Schwalbe Racing Ralph ADDIX MTB 27.5" Tire is available in two versions: The Addix Speed version features low rolling resistance, while the Addix Speedgrip adds improved traction and grip without compromising rolling resistance.


  • Race-ready tire with low rolling resistance and relentless traction.
  • Off-center open tread pattern rolls fast while digging in for aggressive cornering.
  • Tubeless compatible.
  • SnakeSkin Sidewall Protection for anti-puncture defense.
  • Folding bead.
