Are these any good for a cycle-cross bike?
I've just bought some "Schwalbe Marathon Original GreenGuard Rigid Road City" tyres as I'm commuting quite a lot at the moment. They seem like good tyres but they're so heavy, the bike is noticeably heavier since I put these on. (The cycle-cross tyres that I had were quite soft, and not very puncture resistant).
Essentially, I'm looking for a lightweight puncture resistant tyre that doesn't mind the odd bit of gravel. (I live in Milton Keynes, commuting can be a mix of road, path, slightly gravelled path).
