The Ardents I’ve tried have been hateful things. Not light, not robust, not fast rolling, not grippy and can break traction quickly.
Fine for summer dry trails, but then so are most tyres.
My Rocket Ron and Racing Ralph combo are so much better for summer and trail centres, so fast!
I’ve bought a pair of Nobby Nics that I’m looking forward to trying out. 2.4″ front and 2.25″ rear, I’m quite impressed with how the tread actually differs on the different widths.
