Which Tyres?

that could be a bummer for me

It is.

28mm is large enough to reduced the risk though, especially at a lower pressure.

How are Vittoria Open Corsa CX Clincher?
Suitable for riding in and around London?
My Duranos are perfectly fine (great tyres and I can't remember the last time I had a puncture) but I've never tried Vittorias.

You'll be chasing luck instead of sanity.

They're a 320tpi race tyre, take from that what you will.

How are Vittoria Open Corsa CX Clincher?

Best look at the Open Pave instead if you want Vittoria.

By riding in and around London, do you meant commute?

I've ridden GP4000 II's and One's for some time and both of them were fine durability wise.
I work as a courier so not quite commuting. Would pluck for Open Pave's but they're always exceptionally expensive.

Always good to have another opinion to consider

Just had a look on the veloflex website where it says they can be inflated up to 145psi (compared to 120 for GPs) which may well be worth it for the track

But the GP4000 II is not exceptionally expensive?

The TOUR, Europe's largest racing bike magazine (12/2014): "Perfect allrounder … smooth ride, the steering behaviour is neutral … very good wet weather grip … high puncture resistance.” The TOUR carried out a 6,000 kilometre endurance test: "Although lighter than the immediate Continental competitor, the ONE nevertheless has plenty of rubber on the tread, resulting in a respectable service life. The rear tyre was puncture-free for almost 6,000 kilometres: it has become slightly angular, but is still well protected against cuts and small stones. As far as the front tyre is concerned, apart from the puncture caused by the blackberry bush thorn in Southern Italy, the distance was covered with virtually no problems.“

I think I managed to get them quite cheap (£28 or so) but in retrospect, I much prefer the One and wouldn't bother paying extra for GP.

That's a test of the clincher isn't it? The tubeless version is not light.

Isn't a Durano perfect for couriering? If your busy, flats cost you jobs.

Yep, but I hope the tubeless will have similar properties.

Similar properties to a One with butyl tube. Latex would be quite different I think.

At least you'll have magic latex spunk in them to seal punctures.

Fair point, the One in Wiggle is unde £27 as we speak.

Meh, I used to get 4000k out of ProRace in Oz before they'd start letting stuff through.
Zee Germans have much nicer roads than here. I'd be saving Ones for times I needed to go a bit faster.

Got some new 25mm Duranos to throw on the training bike when I get a chance.

They basically are. I genuinely can't find a single bad thing about the new versions so I'm not sure why I'm even in this thread.

So has Norfolk and Wales.

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.

Super happy with open paves.
Great all round tyres.

if only they came in a tan wall

They come in a green wall, that's sufficient. They're a tyre for bad conditions, gumwalls would get shitted up really quickly.

This is pretty good;

I'm still debating trying out 4000s.
