I have been using them for a few weeks as I do a bit of road riding. They do roll really well..I have the 2.1’s which look more like 2.0’s.
I also use them up at Lee Quarry and general bridleway/footpath riding around Rossendale/Todmorden. I think they’re excellent in the dry not too sure about the wet though. They were a bit skittish in the mud but I try and avoid lots of mud where possible.
As a back tyre they should be excellent…..I am thinking of getting something a bit grippier on the front but havent got round to it yet
