S-Tubo-MTB: The Ultimate Spare Tube for Mountain Bikers
Weighing in at just 39 grams, the Tubolito S-MTB is the perfect spare tube for riders who demand performance without the bulk.
Engineered for mountain biking, it's not only ultra-light but also offers better rolling resistance than standard butyl tubes—giving you an edge when every watt counts. Tough, compact, and reliable, the S-MTB is the smart choice for those who want to ride further, faster, and worry-free.
Built tough for demanding terrain, it's also fully compatible with tubeless setups—residues of tubeless sealant are no problem.
Small in size. Big on performance.
TPU – high-tech material for the highest demands
All Tubolitos are made from the high-tech plastic TPU. TPU has been used successfully in the industry for many years and is valued for its outstanding performance.
The founders of Tubolito, Ákos Kertész and Christian Lembacher, have been working with TPU since before founding Tubolito and have built up extensive expertise over the years.
The combination of TPU with a patented manufacturing process makes it possible for Tubolitos to be small, lightweight, and at the same time puncture-resistant. These properties can be optimised depending on what is required from the Tubolito.
