The Big One Evolution is a real son of a beach. The inspiration for this cannonball belongs to Schwalbe's Dutch neighbors. In winter, their passion for MTB competitions moves on to the beach. They wanted to create the fastest tires for beach racing. Huge volume. Minimal profile. Minimum weight. In addition, they use the latest Tubeless Easy technology. The result is a tire with the lowest rolling resistance Schwalbe have ever created.

- Lighter, grippier, faster - The ''Turbo'' of spike tires - Agile and sporty - Please note, in order to ensure that spikes are permanently fixed, tires should be run in for about 40km (25 miles) on asphalt, while avoiding any fast acceleration or heavy braking.
