Sick of having to carry around a big, bulky, heavy spare tube in case you have a blowout on the trails? Well, Tubolito is here with the perfect solution! The Tubolito S-Tubo MTB Tubes are even lighter and more compact than the standard Tubolito tubes and they have a removable valve stem so you can roll them up to a teeny tiny size of only 3.5 x 5cm for the ultimate in convenience and packability. Perfect for an emergency spare when running your tyre tubeless!

Tubolito S-Tubo tubes are manufactured from a special thermoplastic elastomer that was originally developed for use in speaker cones of all things. They are far less bulky than standard butyl inner tubes and can easily be slipped into a pocket or strapped to your bike without taking up too much space. The puncture resistance of the S-Tubo is the same as standard butyl rubber tubes with a weight of only 45g (for 29″).

Who's this item for: These tubes are the perfect choice for anyone wanting a lightweight spare to carry around. Enduro racers will love the S-Tubo because of its extremely low weight and small pack size.

Removable valve core: The whole valve stem on the S-Tubo is removable to allow for a crazy small pack size when it's rolled up.

Weight: 43g

Materials: Some kind of magical thermoplastic elastomer.

Pros: Far lighter and less bulky than standard tubes. Removable valve stem allows for super-compact storage size.

Cons: Convenience does come at a cost and these tubes are quite a bit pricier than the standard variety.
