Which Tyres?

I found these: https://www.sigmasports.com/item/Specialized/Roubaix-Pro-Clincher-Tyre-700X25-28C/DI04

..I think they are 28's with a 25 tread? Don't really understand..

I have these as a stand-in on my surly, they're fine. Stickers come off easily enough. Can't say I've done many miles on them yet. Should take the width easily

Tl;dr: they're all the same.

Good find, leaning towards 32mm commuter but thinking gp5000 tl will be too flimsy.

ALWAYS go back to 4 seasons. But would be nice to have something a little more gravel orientated.

Jan's latest crap for a good morning laugh:

• Some of our tyres have lots of small holes in them, so piss all the sealant out, if you get one of these too bad, just send it back to us and we hope the next one won't be like that
  
• Super thin tyres get fewer punctures than thick ones
  
• Wider tyres force you to ride off pavement more, so there'll be less broken glass around, so you won't get as many punctures, so stop complaining
  
• You should fit literal windscreen wipers for your tyres that are 18 dollars each
  
• If it's rocky you should magically "let the bike move around under you more", then you won't have any more punctures
  
• You must redesign your flat to keep your bike away from any electric motors or the tyres will break down and die
  

I'm still of the school of thought that, unless racing, where I care about Crr, I'd rather be riding than stopping. With that in mind I will continue to run big, durable tyres and deal with the slight drop in speed/increase in power required.

lolz

about 38c slicks, tubeless for anything but racing. Was thinking on travellings, which other options that doesn't cost the earth?

Good autocorrect of gravelkings

agreed
his blog has turned to an absolute crock of marketing bullshit

Saying that, I swapped the >1kg Crazy Bob tyres on the singlespeed for some Kojaks. So sweet. :)

GP5000's I can't get my head round why the big jump in weight from 28-32....
Weight: 23c - 200 grams / 25c - 215 grams / 28c - 235 grams / 32c - 290 grams

It seems that they run truer to size now though, how are people getting on with them?
Also what is the best match inner tube wise for 32c for a road bike, as I've been running 28 race with my Gp4000ii 25c.

oops sorry wasn't meant to be a reply!

Also stumbled across these.... they'd have to be pretty good for £28!!

Claimed weights are always all over the shop.

No one running 28 and 32mm tyres should be caring about tyre weight.

"The GP 5000 TL is available in the 25-622, 28-622, and 32-622 sizes. As usual, we're testing the 25-622 version which has a specified weight of 300 grams. Our sample comes in slightly below the specified weight at 295 grams."

Specified weight of the 25-622 Grand Prix 5000 is now 215 grams while the Grand Prix 4000S II was specified at 225 grams. Surprisingly, my sample of the GP 5000 comes in at 221 grams which is more than my sample of the GP 4000S II that I've tested back in 2014 (which was a very light sample) and came in at just 215 grams.

Not bothered per se, I’m thinking of going with the 32s for TCR. I’d like to carry a spare if I can make that work.
I guess I’m weighing up options, boom tish

Challenge Strada Bianca Tire 36-622 TL-R - Black/Brown

Anyone tried these for longevity ?

Throughout winter I have used Continental Top Contact Winter 37 mm, but now trying to mount my Marathon GGs 35 mm from previous bike front fork doesn't clear them with mudguards. Any recommendations what should I go for? It's IGH belt-driven bike, so I want to be safe from hassle with punctures, but at the same time remain quick. 32 mm Marathons? 37 mm Conti Contact Speed?

Marathon Supreme

So what is the forum approved road tyre and width at the moment? Was thinking 25mm Contis of the posher variety...

Marathon green guard come in 28/32 so if you get on with them, go for it. If it's punctures you're trying to avoid, they're pretty much bomb proof.

vittoria voyager hyper 35, such a good tyre

Marathon GG 35 doesn't fit under guards so I doubt Vittoria could sadly.
I remember test at bicyclerollingresistance had some strange results with Marathon 32, was it just a faulty piece or it really worse than the wider ones?

Conti gp4k/gp5k if you are prone to punctures, otherwise Vittoria Corsa.

Has this been mentioned on the forum? I can't find anything on the search.

Any thoughts? Corsa G+ are my go-to, but at the moment I'm running Turbo Cottons. The latter are ready for the bin (through delamination rather than wear), and I was just about to buy another set of the former.

I'm not sure whether this is scare-mongering or a genuine issue - there seems to be no scientific evidence to back up their claims, to the point where they're kinda leaving themselves open for the finger to be pointed back at them.

Really don't want to buy black tyres, but also really don't want the sidewall to blow out.

(FYI - I have non-Enve carbon rims)

Quite a few years ago Veloflex discouraged the use of their Record clincher on carbon rims after quite a few people noticed failures.

Run a careful eye over your turbo cottons around the bead and judge for yourself?
