SCHWALBE EXTRALIGHT SV20 inner tube 700x18/25c Presta 80 mm

Extreme tightness!

This inner tube developed by SCHWALBE is manufactured with a rubber compound.
As a result, you won't have to reinflate as often, because you won't lose as much air!

Highly reliable, each inner tube is pressure-monitored twice during the manufacturing process.
