What fast 28c tyre?

freefall_junkie

I am considering sticking 28c tyres on my Bianchi Infinito CV, partly because some of the roads around me are in a pretty dire state, but also because the frame is designed to take wide tyres and I am interested to see what they are like. I read that recent tests in a German magazine suggested that 28 tyres actually had less rolling resistance than either 23s or 28s, negligible increased aero drag and a relatively small increase in weight, so I am curious. Several of the 28c tyres around seem to fall into the heavier winter/training category, but I am looking for something light if possible. Continental launched a 28 version of the Grand Prix 4000s recently and that would seem to be an obvious choice. Anyone tried these or are they any other I should consider?

Thanks,
Mark

Those are the ones I was going to suggest! Although I'm not sure if anywhere has availability yet?

I've got 28mm Conti GP 4 Seasons on one of my bikes. They roll well, good grip, and did Valenciennes to Roubaix (45km of pavé) last month without any punctures. Recommended.

Ive got clincher 28mm four seasons on my classics build and they are excellent. I prefer the 27mm pave tubulars on my one of my other steeds ( older infinito) for the feel and comfort of slightly lower pressures but the 4 seasons can be run pretty low.

I run 4 seasons in 28mm on two bikes. They are an excellent tyre. Fairly fast, very heard wearing, but plenty grippy.

The new 4000s II in 28mm are not shipping yet, to the point where wiggle cancelled my pre order and I have gone with the 25.

Interestingly, and I haven't measured them with a caliper, but the 28mm 4 seasons versus the 25mm 4000s - there isn't 3mm of difference on the same rim. They are pretty damned close.

Yet to ride the 4000s in anger. I only want them for a longer TT this year and will almost certainly stick with 4 seasons for the proper long stuff.

Thanks for the replies everyone.

I had read elsewhere that the 4 Seasons 28 comes up a bit narrower than 28, although no doubt the rim width will affect this. Can't find anywhere with the 4000s 28s in stock yet but I think it might be worth waiting - happy to use my Hutchison Fusion 25s for the time being.

I found a link to the Tour magazine wide tyre test on the Conti website - makes interesting reading http://www.conti-tyres.co.uk/conticycle ... e_2014.pdf .
The 4000s 28s come out very well.

I can recommend Challenge Paris-Roubaix, they are quoted as 27mm, not cheap, but Vanilla Bikes were the cheapest when I bought them a couple of months ago.

I've just put the 25mm 4000's onto Velocity A23 rims, and they are measuring 27.8 mm with calipers.

I just buy what I like.

Sometimes that means I have stuff lots of other people have and sometimes its well exotic.
You get grief for both but I only try to please myself.

I quite like when its a popular thing as its often easier to get hold of and cheaper.

I can see why a woman would not want to be wearing the same dress as another woman at a party/function, but tyres on a bike? Really??

Glad I ordered the 23mm ones now then!

I have the 23mm 4000's on DT Swiss RR475 rims, and they measure 23.4mm, rim width makes quite a difference.

Interesting. I am running them on Archetypes and they do look very much as wide as 28mm 4 Seasons.

I am not going to complain - though I dread to think just how wide the 28 4000s II actually come up.

I will take the tyres out into Richmond Park later on - but I don't expect to see some miraculous speed gains with the wind as it is currently!

Vittoria Open Pave's 27mm on archetype or other wide rims are 27mm which is close they have been around for years and are an excellent tyre.

bendertherobot

Michelin Pro 4 25C come up at pretty much 28c

great tyres
