Schwalbe Sv21
Presta (SV), 27.5", 40 mmProduct details
Standard MTB tube with French valve. The Schwalbe SV 21 tube is one of the most reliable tubes in its class. A Schwalbe tube holds air significantly longer. The quality of the materials and the purity of the rubber mixture determine the quality of the tube right from the start. During vulcanization, each Schwalbe tube is placed in a mold and inflated. This is the only way to ensure uniform wall thickness and excellent air retention.
