The perfect replacement inner tube for Brompton folding bikes. 

Due to innovative processing of a special material Tubolitos are not only lighter but also more robust than classic tubes made of rubber.

To measure the puncture resistance of a bike tube the needle penetration test is an important parameter. It measures the force needed to puncture a tube with a test mandrel. This test indicates: compared to standard rubber tubes twice as much force is needed to puncture a tube of the Tubo-MTB.

Almost half the weight of a standard Brompton replacement tube. 

Schwalbe AV4 85 g

Tubolito 43 g

Select the Schrader valve version if you are replacing tubes on a factory Brompton bike. 

Fits:

30-349, 32-349, 35-349 tires
