The Schwalbe tube No.19F is compatible with 29" and 29+" (or 28") tires with a width of 54-75 mm and is primarily used in mountain bikes, but it also fits trekking bikes. The Schwalbe Freeride impresses with a large volume while maintaining a low weight. Thanks to their excellent craftsmanship, Schwalbe tubes have proven themselves in the market for many years. They are uniformly thick-walled and perfectly round in shape. Their precise seams make the joints robust. A comparative test has shown that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost nearly double the air pressure of the Schwalbe tube in 30 days). One possible reason for this could be a lower butyl content in the other tubes. The exceptional quality of Schwalbe tubes arises from the uniqueness of their rubber mixture. To ensure this high quality, each Schwalbe tube is inflated and inspected for at least 24 hours before leaving the factory. Features: - Freeride – low weight (215g) - Butyl rubber ensures double air retention - 24-hour test for each tube - High elasticity allows for covering many tire sizes per tube - Recycling process results in a very good energy balance Suitable for tire sizes, among others: 54-622 | 28 x 2.10 55-622 | 28 x 2.15 57-622 | 28 x 2.25 60-622 | 28 x 2.35 62-622 | 28 x 2.40 54-622 | 29 x 2.10 55-622 | 29 x 2.15 57-622 | 29 x 2.25 60-622 | 29 x 2.35 62-622 | 29 x 2.40 65-622 | 29 x 2.60 70-622 | 29 x 2.75 75-622 | 29 x 3.00 Valves: - AV = Auto, Schrader - DV = Dunlop, Blitz, German valve - SV = Sclaverand, Presta, French valve (40 mm) Delivery includes: - 1 x Schwalbe tube No.19F including valve
