The new Flat-less tyre. After 10 years, Schwalbe have thoroughly overhauled the Marathon Plus. The only true flat-less tyre gets a new, dynamic profile and boasts many internal improvements:

Rolling Resistance. The patented, 5mm thick SmartGuard layer, when compared to all generic products, has a significant advantage in rolling resistance. Schwalbe further extended its lead in the latest version.

Recycling. Also in the SmartGuard, Schwalbe 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 50km/h. Following sizes carry the ECE-R75 mark:
20 x 1.75”, 26 x 1.75”, 700 x 35mm and 700 x 38mm

SmartGuard
Most effective protection belt available for bicycle tyres. A substantial, 5mm thick layer of flexible, special india rubber offers durable protection. Works also for objects that lodge in the tread. Even a thumbtack won’t harm it.
Flat-less

Note: It is impossible to guarantee that a flat will never happen, but the Marathon Plus has the best defence against everyday tyre wreckers such as glass, flints or metal shards. Use a pressure gauge to adjust tyre pressures as the common ‘thumb check’ is insufficient due to the special construction of the Marathon Plus.

Thanks to its thick layer of springy sub-tread rubber - called SmartGuard - the Matathon Plus is virtually immune to through-the-tread punctures. Even drawing pins do not penetrate the rubber. The steel-beaded sidewalls are gumwall and are fairly tough too. Where the Marathon Plus scores over the Conti is its vast range of sizes - including 700 x 25mm. This takes 115psi (8bar) and it rolls suprisingly well, even if the handling is somewhat leaden. There's a Scotchlite strip and dynamo track on the sidewalls. Although it can be a little difficult to change these tyres, they are unlikely to puncture so this isn't a job you'll do that often.

Weight: 708g
Pressure: 70-115psi

Cycling Plus rating: 8/10 - "Almost impregnable. Heavy and hard to fit, but faster than you'd think"
