Less is more: Tubo-MTB combines low weight and increased toughness. For 29” tires you’ll save more than 100 g per wheel compared to standard butyl tubes and get 2X the puncture protection. In addition the packed tube size is reduced by half. Tubolitos are easily mounted and are a super lightweight alternative to tubeless systems. Ready for disc brakes.

Tube Material: thermoplastic elastomeer (TPU)
Max presure: up to 8 bar/115 PSI. 
Outside the tyre your tubolito hose should never be filled with a pressure above 0.5 bar. Otherwise, there is a risk that the tubolito will overstretch or burst.
Do not remove tubes and use them in differently sized tyres. For example we do not recommend that you use a tube in a 28mm road tire and then mount this same tube in a 22mm wide tire. The tube has a plastic deformation, meaning that it does not go back to its original shape after inflating in the tire.
