Schwalbe No. 21F Inner Tube - 27.5/29" | Extralight

Extremely pressure stable!

The rubber compound makes it possible. Due to the high proportion of pure butyl rubber, the Extralight hose holds the air significantly longer than conventional bicycle inner tubes. Less air loss and less frequent pumping. Each Schwalbe tube is checked twice at the factory for tightness. Ideal for riders who value large volume at low weight
