Schwalbe SV19-AE+ 29" Aerothan Presta Inner Tube

The Schwalbe SV19-AE+ 29" Aerothan Inner Tube is a lightweight, tough, and fast-rolling tube for 29" mountain bikes. Made from 100% thermoplastic polyurethane, it gives strong puncture protection while keeping weight low. It is about 40% lighter than Schwalbe Extralight butyl tubes and is built to reduce rolling resistance to a tubeless level. It is also fully recyclable, including the valve, which makes it a more responsible choice when it reaches the end of its life.

Key Features and Benefits:

• 100% thermoplastic polyurethane construction: The tube is made from TPU, including the valve, which keeps the structure light, strong, and fully recyclable. This gives you a tube that cuts weight without losing key protection and can be returned through Schwalbe’s tube recycling programme.
• Around 40% lighter than Schwalbe Extralight butyl tubes: The Aerothan material saves notable weight compared with standard lightweight butyl options. This helps reduce rotating mass, so the bike can feel more responsive when you accelerate, climb, or change pace.
• Very low rolling resistance: Aerothan is designed to roll with resistance levels close to tubeless systems. This helps reduce energy loss as the wheel turns, so more of your effort goes into forward movement.
• High puncture resistance: The TPU material gives strong resistance against sharp objects and impact damage. This helps lower the risk of flats, which supports more reliable riding on rough ground and longer routes.
• Stable ride at low air pressures: Aerothan tubes are built to hold their shape and performance well when tyre pressure is reduced. This helps improve grip and control while still giving the support needed for 29" MTB tyres.
• Easy fitting without slipping or jamming: The tube is designed for simple mounting and a secure fit inside the tyre. This helps reduce fitting issues during installation, so setup is quicker and more consistent.

Lower weight, strong puncture protection, and low rolling resistance make this tube a smart upgrade for riders who want better efficiency without moving to a full tubeless setup. The heat-resistant TPU build also helps maintain dependable performance under load, while the stable low-pressure feel suits off-road riding where grip and control matter.

Choose the Schwalbe SV19-AE+ 29" Aerothan Inner Tube for a lighter, more efficient tube that adds protection and keeps your bike ready for demanding rides.
