Which Tyres?

Aren't Ones a bit delicate for general riding/commuteering? Thought they were a race tyre.

Yes, this. I've been using them for more commuting than usual on the road bike and they've cut up really badly and are starting to flat with monotonous regularity now. Lovely ride, but definitely for best only long term. Not even as durable as the Ultremos they replaced.
