I have lots of experience with the Terreno Dry (that is actually faster than the Zero) which has the same side knobs. Fantastic summer off road tyre but those side knobs aren't nice cornering on tarmac, however that applies to just about all off road tyres. Specialized Roubaix 30/32 are my go-to winter road-with-a-small-bit-of-off tyre now.
