"Souplesse" or Flexibility makes the difference: Tubeless technology of a new dimension: Schwalbe's Pro One will win you over from the first pedal stroke, with a focus on speed, grip and safety. The tyre also provides easy rolling flexibility.With the Pro One Tyre the goal was to develop a fast, lightweight and safe tyre which at the same time offers maximum flexibility. It's a tyre which quickly and accurately responds to a cyclists riding style and always provides sensitive feedback. All this means the rider gets less fatigued and can achieve greater performance. The new turn up construction integrates Tubeless Easy Technology in the most progressive way possible. Two carcass layers underneath the tread renders the tyre smooth, comfortable and puncture resistant, while three lateral carcass layers ensure high cut resistance. The V Guard Puncture Protection is made of a specifically developed hi tech polymer fibre that is also used for bullet proof and stab resistant vests. It provides excellent protection from cuts and punctures, and at the same time, it is extremely lightweight. Neither the rolling resistance nor flexibility of the tyre are compromised by the V Guard. **ETRTO:*** SCR371A: 25-622* SCR372A: 28-622* SCR376A: 25-584* SCR380: 30-622
