Schwalbe Inner Tube SV20 700 x 18/28c Extra Light Presta Valve

The Schwalbe SV 20 700 x 18 – 25 Presta Valve inner Tube would be one of the finest inner tubes a human could put inside of a bicycle tire. This is a race grade inner tube. All inner tubes from Schwalbe with yellow on the box have a valve stem 40mm or 60mm long. 

At 65 grams this inner tube is light. The valve stem is standard Schwalbe issue which means you never have to worry about it, but the inner tube itself has been made lighter while at the same time not compromising the tubes’ ability to hold air. This is what you’d expect from a race tube.

In reality, there are not that many bicycle inner tube manufacturers. While Schwalbe up until recently has not been a road racing themed tire manufacturer, whatever they produce is always top quality and worthy of consideration by the most elite of cyclists. Flash forward a few years and now Schwalbe has a lot of racing tires, but they have been making this race tube for years and years.

This inner tube only fits tires from 18 to 25mm wide. This tight range means the rubber in the tube has a different compound than other tubes that stretch more. This tube is designed to hold more air without getting large. You will be happy with it because it is light, easy to install and has a great valve stem with all the replacement parts possible.

• Each Schwalbe tube is individually examined twice at the factory to ensue air-tightness
• Size: 700c x 18/23mm
• Valve Length 40 or 60mm
