Best summer tyre?

I went out looking for the Pro Race 3s in 25c width when they decided to discontinue them and everyone put them on clearance sale. Unfortunately, they were all gone in the blink of an eye. The Pro Optimum was supposedly similar, so that's what I ended up with. Smooth and grippy--pretty light too.

Conti gp4000's no question

I agree that Gp4000s are a great 3 season tyre, I have them on two pairs of wheels.

But if you really want something special for your best summer wheels try a pair of Velofex pave or master and key point partner them with latex tubes. These realy zing, a bit like old style clement tubs strada66/crits tubs. i've lost count of the number people who have asked if they are tubs.

I used them on the 'Ride with Brad' event last week and they where fine, even on the err farm tracks used for the last 10km. Reckon I've put well over 1000mile on them since May and so far (dare I type this) no punctures, I did pick up the odd cut from last week.

Ok going latex means you need to re-pressurise once a week, but the ride, feel & zip is worth that little effort

As you mentioned 25/28mm, and Veloflex are more like 23 .... Clement Strada LLG 25c are also getting good feedback in my LBS, but they have the nasty black sidewalls that unfortunately is common these days. (I prefer the old school look)

oh when is/was summer?

GP4000s are probably the best all round tire you can get.

In your configuration the best way to go would probably be Ultremo ZX 28mm on front and GP4000s 25mm on rear.

Ultermo ZX are quite light weight and are not as puncture resistant when on the rear as GP4000s, but I find all very lightweight tires are can be used on front without problem - had about a few thousand KMs from a 25mm ZX on front with only a couple of punctures.

If you wanna stick to 25MM - you can get 2xGP4000s from Rose bikes fro about £48 with a facebook voucher.

Why d'you think?

GP4000s.

No further comments please.

is that so? I've never thought of that - and would often put 23mm front, 25mm rear. Would it also be more stable, the way you describe?

Conti Gp4000s. Fit and forget. Light, great traction and resilient to 90% of punctures!

If puncture's really get you down, look at the gatorskins.

A lot will probably say michelin pro race, although I've never tried any. Always used conti's myself.
