Schwalbe Air Plus Innertube 24x2.1/2.8

Due to the high proportion of pure butyl rubber, the Schwalbe Air Plus tube retains air significantly longer than conventional bicycle tubes. Therefore you have to inflate less often. With around 70% greater wall thickness, the Schwalbe Air Plus is particularly robust - and so it's well protected against pinch and penetrating punctures. If the Schwalbe Air Plus ever needs to be replaced - like all other Schwalbe tubes, it is 100% recyclable.
