The Schwalbe Marathon Plus SmartGuard (37-622 - Black with Reflective) tire is the only bicycle tire in the world that can claim to be "flat-less." This is thanks to its unique, patented puncture protection layer—five millimeters thick and made of special, highly elastic rubber. Even thumbtacks can't puncture this tire! But the new Schwalbe Marathon Plus isn't just "flat-less." It now rolls lighter than ever and, thanks to its "Anti-Aging" sidewalls, is incredibly durable. It's also suitable and certified for fast e-bikes.

Features Schwalbe Marathon Plus SmartGuard

Rolls lighter

The unique puncture protection layer makes the Schwalbe Marathon Plus slightly heavier. Although the Marathon Plus weighs a bit more, its rolling characteristics are excellent. The laboratory test objectively confirms what one can already experience subjectively on the bike: the new Marathon Plus rolls significantly lighter than other bicycle tires with a comparably thick puncture protection layer.

Longer lifespan

The original Marathon Plus is now protected against premature aging due to weather influences or overloading due to low air pressure. We've developed a special "Anti-Aging" technology. This makes the sidewalls of the Marathon Plus extremely resistant to unsightly cracks.

In addition, the Marathon+ lives up to its name with a new rubber mix: the Endurance compound rolls thousands of kilometers with excellent handling and low wear.

Saves natural resources

The Marathon Plus's puncture protection layer is extremely elastic. This is doubly important – for total protection and for dynamic rolling. This high elasticity can only be achieved with a special rubber compound containing a high percentage of natural rubber.
Natural rubber is a valuable resource. Recycling is only available at a very expensive cost. Despite this, Schwalbe chooses to do so. The new Marathon Plus's puncture protection layer is therefore made partly of recycled natural rubber.

Excellent bicycle tire for E-bikes

E-bikes are a hot topic. Crucially, they're fitted with exceptionally stable, puncture-resistant tires that are durable. The Marathon Plus naturally meets all the requirements for an e-bike tire. This applies not only to e-bikes with pedal assistance up to 25 km/h. The new Marathon Plus is certified in all common sizes with the European quality mark for e-bikes up to 50 km/h. The following sizes have the ECE-R75 quality mark: 47-406, 47-599, 37-622, 40-622, and 47-622.

Level 6 | SmartGuard

The most effective puncture protection available for bicycle tires. A solid, 5mm-thick layer of elastic, special rubber provides long-lasting protection, even against objects already driven into. Even a driven-in pin will remain "stuck" in the rubber without causing any damage.
