CX / Gravel: Not only a spare: It is not only a savior in need, but can perfectly well also be used on a daily basis as it is still as robust as a standard butyl tube. It is developed to fit in any small pocket.

The 35 grams lightweight S-Tubo-CX/Gravel-All is the ideal spare tube for all 700C and 650B tires with a tyre width from 32 - 50mm due to its very small packed size. Leftovers of tubeless liquids do not do any harm to it. Given its low rolling resistance, it can also be the decisive advantage at competitions. Available with 42mm (35 grams) and 60mm (36 grams) Presta valves and suitable for disc brakes only.

S-TUBO
Are you chasing records? Always looking to have the lightest bike? Are you trying to minimize rolling resistance? Or are you a tubeless rider who wants to have a light and small spare tube?

We do have something for you: our S-Tubo technology. S-Tubo products are characterized by the reduced wall thickness of the tubes. Therefore they are even smaller, lighter and have a very low rolling resistance. S-Tubo-Road for instance is the lightest bicycle inner tube worldwide and does have a rolling resistance comparable to latex tubes.

S-Tubo is our performance line. Despite all these characteristics S-Tubos have the same puncture resistance as standard butyl tubes. Due to the reduced wall thickness they are a little more prone to be harmed by potential heat during long and hard brakes so they are only ready for use in bikes with disc brakes.

S-Tubo technology currently is available for road bikes, MTBs, CX/Gravel and BMX bikes.
