I want to confirm whether it's me or it has happened to others.
Has anyone noticed a huge difference in durability between the good old Marathon XR's and its sucessor the Mondial?
I used my XR's up to 18.000 km without major problems. Now, my first Mondial is already 8000 km and it's almost completely smooth.
I came a across a german guy recently and he said that Schwalbe deliberately lowered the quality because the XR was too good in quality and too bad for business. My recent experience confirms this 100%.
Does anyone have the same feeling/experience?
