i can heartily recommend the Clements, i’ve got the Strada LGG 120tpi in 28mm for road duties and they’re very fast, very grippy as the recent downpours on baked dry roads left a very slick surface to ride on and the LGG has chevrons on the edge using a softer compound that have prob saved me hitting the deck a few times now, i have felt the front end sliding away but it soon grips and i start to breath again.
For offroad duties i have the Xplor-Mso 120tpi in 40mm and they are ace for heading out with the mindset “head for the hills”, cope very well with fireroads,greasy grass and they cope well with rocky surfaces, not had much of a chance to try them out on mud yet but i guess the PDX Clincher would be the tyre of choice for those conditions.
I don’t race cross so can’t comment regarding that but they’re fitted to my Kinesis Tripster ATR and i ride that everywhere i would take my Hummer.
