Our most popular cross country tyre and Schwalbe's most successful competition tyre - in the right conditions you can't go past the Racing Ralph. The original Racing Ralph was good - but that wasn't good enough; so it went under the knife and received even greater cornering traction without compromising straight line speed and traction. Less understeer and more stability sounds like a win-win to us! Thanks to its perfect combination of speed and grip this racer inspires. Works perfectly on the rear wheel in combination with Rocket Ron. Tread Design: low tread depth in the central tread for high speed and low weight.
