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.
