SCHWALBE MARATHON PLUS 20" SMARTGUARD TYRE

The new Flat-less tyre.

After 10 years, we have thoroughly overhauled the Marathon Plus. The only true flat-less tyre gets a new, dynamic profile and boasts many internal improvements: Reinforced SmartGuard protection layer shields against punctures from thorns, glass, and sharp objects. Enhanced rubber compound delivers superior grip and durability on all terrain. Optimised tread pattern reduces rolling resistance while maintaining excellent braking performance. Lightweight construction improves acceleration and handling without compromising flat-free reliability. Tubeless-ready design offers flexibility for modern wheel setups. Extended lifespan means fewer replacements and better value over time. Built for commuters, touring cyclists, and adventure riders who demand dependable, maintenance-free performance. Whether navigating urban streets or rough trails, the Marathon Plus20 keeps you rolling without interruption.

Features

• Rolling resistance. The patented, 5 mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. We further extended its lead in the latest version.
• Recycling. Also in the SmartGuard, we now use a proportion of recycled rubber from old latex products.
• „Anti-aging“ side wall. It now lasts much longer before developing unsightly cracks when subjected to use with too low air pressure.
• E-Bike ready. The main sizes are approved and tested for E-bikes up to 50 km/h. Following sizes carry the ECE-R75 mark: 47-406, 47-559, 37-622, 40-622, 47-622.
