I’m running Sammy Slicks at the moment on my all round pub hack/gravel/arsing about with the kids/anything you can throw at it bike. They seem to work well on any surface i’ve thrown at them so far. They’re pretty slick when upright so roll very well on smooth surfaces and roads, especially when you pump them up, and have nice nobbles on the edge which work great when you’re cornering on grass or soft surfaces or even when things get a bit muddy. I’ve got the ones with the addition puncture protection and so far only had one puncture which was a pinch flat – I think my rims are too narrow for them. But that issue has been fully addressed with more air! at the expense of some comfort though.
Not the only option but i’d heartedly recommend them.
