A stable inner tube with Presta valve for 29 and 29+ inch tyres. This inner tube is best suited to tyres with a thickness of 2.1-3 inches.
The Schwalbe SV19F inner tube retains air significantly longer thanks to the pure rubber compound. In addition, Schwalbe can guarantee an even more uniform wall thickness with low weight thanks to vulcanization in a mould. Thanks to its high elasticity and top quality, this inner tube covers several tire sizes. Only an extremely high-quality and reliable inner tube like this one from Schwalbe can cope with such demands.
