SCHWALBE REIFEN MR+ MTB;57-559 B/B+RT PERF 
 
THE "UNPLATTABLE" MTB TIRE. With ECE-R75 test mark for fast e-bikes. On the central bridge, it rolls easily over fixed paths. The strong outer studs have bite in the terrain. The SmartGuard offers superior puncture protection. Good visibility even in the dark thanks to reflective strips on the side walls. Available in 26", 27.5" and 29".
You can never completely rule out a flat tire. However, with the Marathon Plus bicycle tire you are well protected against the typical breakdown devils such as shards or granulate. It is essential to use a manometer to set the air pressure on all Marathon Plus. Due to the special structure, a pressure test with the thumb is not sufficient
