About Schwalbe SV15 Road tube presta valve (700x18c-28c)40mm
Made from Butyl Rubber, Schwalbe tubes are well known for its extremely high air retention and elasticity. Schwalbe tubes undergo vulcanization process which ensures constant wall thickness and high air pressure retention.
All tubes are inflated and stored for 24 hours to test the air pressure retention. Afterwards, each tube undergoes a careful visual inspection.
Only a good quality tube can cover very many tire sizes which isn't possible if the tube isn't highly elastic in nature. For example, tube no 17 can fit tire widths between 28mm and 47mm.
About Bike Tubes
Without a good bike tube, the bike is not functional. Though all the components and bike parts go hand in hand. But it’s the tube that keeps your tires hard/inflated and helps them roll smoothly. Choose a bike tube that matches your bike tire and diameter for a correct fit. Presta and Shrader valves are most common valve types available in the market.
For over 70 years Schwalbe has dominated the two wheeled tire industry in Germany and Europe, being voted best MTB tire brand in Germany for the past two years. From the very early beginnings where the company founder, Earnest-Wilhelm Bohle capitalized on the developing cycle industry, to the ultra modern distribution facility near Cologne, Schwalbe has continued to design and manufacture some of the finest bicycle tires available. Schwalbe's success is due in part to the effort it makes in product development from lab tests at the manufacturing facility to the hardest proving grounds of all, professional cycle racing. 'Team Gerolsteiner' achieved a very creditable 7th place overall in 2004 Tour de France and the unique performance of team captain Davide Rebellin winning three major classic races back to back using Schwalbe tire. Other notable successes include Normann Stadler winning the infamous Ironman triathlon in Hawaii, riding Schwalbe Stelvio tires.
