Tubeless system - iiSuper

We've selected the champions in bicycle puncture sealants.

Of the sealants we tested, we liked Joe's, clearly the fastest working sealant we've ever gotten our hands on. Joe's products are used by the best bikers in the toughest conditions.

Almost a third of the world's production of high-end valves and the majority of valves from renowned brands come from a factory that has launched its own product under the name iiSuper. Pressure testing of every valve, design for any rim, special valves for rim inserts, a multitude of colors, extensions and other products in an excellent performance/price ratio. Technology, in-house manufacturing, development and a superior final product - that's iiSuper.
