Schwalbe is releasing an updated Schwalbe Marathon Plus in 2014 according to the latest press release from Schwalbe.
Of particular interest is the tyres are approved for e-bike use...Now Schwalbe is presenting a new version of its Marathon Plus. Despite its thick protective layer, the tyre rolls surprisingly lightly. “Our laboratory test have shown that among tyres with thick puncture protection belts, the Marathon Plus has by far the lightest rolling characteristics", says René Marks.
The side walls have also been optimised. Since the tyre is so substantial, it has often been ridden with too low air pressure. These years of "mishandling" would sometimes lead to cracks in the side walls. Now a special anti-aging technology works to protect the side walls of the Marathon Plus from premature cracking as well as adverse weather conditions. The rubber compound also makes the Marathon worthy of its name: The Endurance Compound rolls for thousands of kilometres with excellent performance characteristics and low abrasion.
The patented ‘Plus’ of the Marathon is still the heart of the tyre: Smart Guard, the protective belt consisting of five millimetre thick natural rubber. The tyre is now partly made from recycled rubber and is therefore resource-friendly.
Here's the press release and a couple of pictures.E-bikers also have equally good reasons to opt for flat-less tyres. The particular demands of the e-bike require an extremely stable, durable and puncture-proof tyre. For this reason, Schwalbe had the Marathon Plus certified in all its popular sizes for use with fast e-bikes. The following sizes bear the ECE R75 mark of conformity, valid throughout Europe: 47-406, 47-559, 37-622, 40-622, 47-622.
