I've done some dry green lanes on mine (Hexhead Adv) they are supposed to be 10% offroad...
They're not TKCs but they are OK, I would not put them on for trail riding but if I had the need to ride some trails i'd not be sitting at the trail head thinking oh shite...
So, what are they like when "making progress" on normal twisty roads?
You know what my requirements are, after Adams spirited ride!
