Schwalbe SV19-AE 27.5/29" Aerothan Presta Inner Tube
- 29" or 27.5" x 1.5-2.50 / 40mm Valve length
- 40% lighter than Schwalbe Extralight butyl tubes
- Aerothan TPU construction
The Schwalbe SV19-AE 27.5/29" Aerothan Presta Inner Tube is a light, tough MTB tube made for fast rolling and reliable protection. Its Aerothan TPU build is about 40% lighter than Schwalbe Extralight butyl tubes, with low rolling resistance close to tubeless levels. It also gives strong puncture resistance, stable handling at low pressure, and a fully recyclable construction.
Key Features and Benefits:
- Aerothan TPU construction: The tube is made from 100% thermoplastic polyurethane, including the valve. This gives it a very low weight, high strength, and a compact form, so it reduces rotating mass without losing durability.
- Around 40% lighter than Schwalbe Extralight butyl tubes: The reduced weight helps lower the effort needed to turn the wheel. This can make the bike feel quicker to respond, especially during climbs, changes in speed, and technical riding.
- Low rolling resistance at tubeless levels: Aerothan is designed to deform with less drag as the tyre rolls. This helps more of your effort go into forward motion, giving a faster and more efficient ride.
- High puncture resistance: The TPU material gives strong protection against sharp objects and impact damage. This helps reduce the risk of flats, so the tube is well suited to rough trails and mixed MTB terrain.
- Stable ride at low air pressures: The tube keeps its shape well when tyre pressure is reduced. This supports grip and control without the tube feeling loose, slipping, or becoming hard to manage during fitting.
- 100% recyclable design: The tube and valve are made from recyclable TPU and can be returned through Schwalbe’s tube recycling programme. Used material is then reused for sealing or insulation products, reducing waste.
Lower weight, fewer flats, and low rolling resistance are key reasons to choose Aerothan over a standard butyl tube. The SV19-AE gives MTB riders a clean upgrade without moving to a tubeless setup. It is easy to fit, resists heat, and keeps performance consistent across demanding rides.
Choose the Schwalbe SV19-AE Aerothan Presta Inner Tube for a lighter, tougher, and more efficient spare or replacement tube for 27.5" and 29" MTB wheels.

This also means an express delivery service is unavailable. We strive to despatch bikes within 3-5 working days. Please note this may change over school holidays and the festive season (November/December). For more information on the process please visit our pre-build page.
