In reply to Martin1978: Hi all. I have a Claud Butler Chinook.

It says designed with mudguard clearance, but it looks tight to me. Saying that, I'm more of a mountain biker than roadie! The guards will stay on once fitted so something tough, cheap, and offering full coverage is more important than weight or aerodynamics.
As for the Marathons, I was looking at the Marathon Greenguard 700x25c.
I am skint, so keeping my usual tubes would save me a few quid!
I might look to fitting panniers one day and doing some touring on it, but for now I just want to commute on it.
