I currently have conti gator skins assuming I rode the same stretch of road , say 20kms at the same effort in same conditions , how much faster would these tyres make you ?

edit: actually, the answer is possibly about 1%-1.5% faster.

Thats actually not insignificant.

The main difference you will find though is that the ride quality will be a lot better. The tyres will be grippier and you'll be able to corner a lot faster (more than 1-1.5% faster )

Whilst on this subject, here (PDF) is a recent Tour magazine test, although it has neither the GP4000 nor the Gatorskin (but does have the GP4000S).

I wouldn't base the decision on speed, unless you're planning on doing a time trial on them.

Gatorskin for puncture protection, GP4000(s) for grip.

I do love my GP4000S, but recently they have been picking up a lot of small pieces of glass - I never had this problem with Gatorskins.

I was gonna get them for Duathlons and tri's and keep the gator skins for commuting through glass-town Tennesse

But I only have one set of wheels so could get fed up with changing tyres every couple of weeks

Thanks

I don't know that I found GP4000s to be that bad puncture-wise. I destroyed a rear one doing an ill-advised skid stop upon arrival at a time trial but they were going relatively OK up to that point. I still have the front one on my Bowery and no punctures in thousands of km.

Schwalbe Ultremos are also worth considering, I have used them more than the GP4000s and they are probably as good as Gatorskins puncture-wise, or at least very close. Possibly a touch better than the GP4000s. Grip and ride quality pretty much the same between those two tyres, I might edge towards the Ultremos.

Note Planet X have quite expensive shipping so they may not work out that cheap unless you are buying something else. Also note they only have yellow and silver which is probably why they are that price. The performance of the coloured tyres is meant to be marginally worse than the black ones, I think they can't put the magic black chilli in the coloured ones.

I wouldn't put Gatorskins on a race bike in summer, that would be a travesty.

Just put a brand new set of GP 4000s on the bike heading to Spain. I hope to climb 1-1.5% faster than I do on Gatorskins.:D

Picked up a set of those Gatorskin Hardshell tyres in CSS for €64. Time will tell if they're any better than the Ultra for puncture resistance.

Cool ill get them so and maybe ya can post up when ya think its our summer time and ill leave them on then, cause met eireann never seem to know !

Also would wraping and taping them in a figure of 8 do any damage , thats way cycological gave me the gator skins to carry

Despite the name, GP4000 and GP4000S are not the same tyre and use a different rubber compound. The GP4000S are well regarded, but the GP4000, which is an older tyre, got pretty lousy reviews, which is why they are going cheap in a lot of places I'd say.

The figure of 8 thing you only need to do with tyres that have a wire bead; those GP4000s have a folding bead and they will come completely folded up like this taking next to no space at all, you may even get them in a box:

The coloured GP4000 use a different compound (ASC), the black ones are the same (Black Chilli.) I pointed out that Planet X only have yellow and silver, so it is the ASC compound.

For the life of me I can't tell that there is any difference between the black 4000 and the 4000S.

EDIT: That is a good price from JEJames certainly, and the black ones which is the important bit.

I have had the GP 4000S for a little over a year now, I find them fairly puncture resistant, but their main advantage I find is the ability to stick like **** to a blanket when cornering on the road, even in the wet. I would strongly recommend them, though they aren't that cheap.
