Dual ply as the name suggests are super tough, if you’ve a problem with single ply then these are the tyres you need, but there’s a catch - they’re heavy and over 1kg a wheel to drag around needs some thought and ideally an uplift. See the post on mid-tyre weights if you’re looking to ride the ups as well as downs.
