"Whether on a dirt track or in the park, at temperatures below zero or when it's wet: These tyres always deliver reliable performance. The Marathon GT 365 for the bicycle is what the M&S tyre is for the car", is how René Marks sums it up. With one limitation: Although the Marathon GT 365 is an all-year tire, when it gets really icy, then the GT 365 needs to step aside for the Marathon spiked tires.
