The Schwalbe Aerothan Race tube is one of the biggest upgrades you can make without changing tyres or wheels—it’s not just another inner tube, it’s a completely different material and ride feel.

Let’s break down what actually matters ????

???? What Makes Aerothan Different?

Instead of traditional butyl rubber, Aerothan uses a thermoplastic polyurethane (TPU) material.

???? That changes three big things:

• Weight

• Rolling resistance

• Puncture behaviour

⚡ Real-World Performance

???? Weight (Huge Upgrade)

• ~40% lighter than standard tubes

• Can save ~100g+ per bike

???? You’ll feel:

• Faster acceleration

• Livelier ride

⚡ Rolling Resistance

• Lower friction than butyl tubes

???? Translation:

• You roll faster with the same tyres

• Feels closer to a tubeless setup

????️ Puncture Behaviour (Very Different)

• Doesn’t “explode” like butyl

• Air loss is usually slower and more controlled

???? Big advantage:

• Safer if you puncture at speed

???? Heat Resistance

• Safe for rim brakes (important for long descents)

???? That’s something latex tubes struggle with—Aerothan doesn’t.

???? Ride Feel

Compared to standard tubes:

• Smoother

• More responsive

• Better at holding shape under pressure

???? It actually feels closer to tubeless, especially on road bikes.

⚖️ Pros & Cons

✅ Pros

• Very lightweight

• Lower rolling resistance

• More puncture-resistant than butyl

• Safer air loss (no sudden blowouts)

• Compact (great as a spare)

• Heat-resistant (rim brake safe)

❌ Cons

• Expensive for a tube

• Not as fast as top-end tubeless setups

• Needs careful installation (can be damaged if pinched badly)

• Patches are more specific than standard tubes

???? Where It Fits (Based on Your Setup)

You’ve been looking at:

• Aero road bikes

• Road tyres like the Goodyear Eagle Sport

???? This is where the Aerothan makes perfect sense.

Best use cases:

• Road cycling (especially performance riding)

• Training + racing

• Lightweight setups
