As a footnote to the various recent 'which tyre?' threads, I felt I should point out that you can get the excellent Conti GP4000S at [url=http://www.ribblecycles.co.uk/details.asp?D=&Cat=&Section=&GenCode=CONTTYRF0321]Ribble[/url] for £20.95 at the moment. A special offer on Conti inner tubes comes with, as well.
For puncture protection, grip, handling, rolling resistance, looks - every tyre characteristic, basically - my experience is that these tyres can't be beat. I fitted them to my Cannondale in June and haven't had a puncture since. Having had five in seven days on my commuter bike's Hutchinsons (they have been on since last June, admittedly), I felt it was time to step in.
Anyway, that's what I've been doing at work this morning
