And they cracked when left in the sun on a commuter bike, so 4 seasons as long as they’re not sunny ones.
No failures to report here in Scotland.
28mm tubeless GP5000s here on my disc bike a TCR advanced pro. Tyres are run at 70psi good grip and no loss of speed from 25s. Comfort big improvement. I think I could run them at 60psi.
Mavic UST with Yksion tyres - the mk1 tyres were definitely a bit thin, mk2s are meant to better. Certainly better in terms of comfort: 85 psi opposed to 110psi!
@kneed, then maybe I should aim for the GP5000s?
Just noticed that Q - sorry. Yes - the 5000s are a bit narrower for sure. If in doubt fit wise for your frame / fork.
Had pro ones in 2018. They didn't last the summer - very weak, tore up easily. Tried GP5000s last spring - still running them. Absolutely faultless.
Running 28mm Schwalbe Duranos (which is being replaced with the One Addix, which is also available in 30mm), definitely a bit less road buzz than 25mm.
It's a good tradeoff for me, a bit tougher and durable than the Pro One / GP5000 type yet doesn't give up a huge amount in rolling resistance.
I wouldn't touch GP 4 Seasons again, I don't think they are any more puncture resistant in the real world than other similar "all season" tyres but they don't grip or ride as nicely as say Hutchinson Fusion all season..... And I'd still use GP4000 or 5000 in winter if it had to be Conti. The claim that GP 4S rubber works better in cold conditions.... Thats never seemed true to me either.
Basically they're dated now.
Im running 32mm Gp5k tubeless and they are brilliant. Grip but roll easy. Comfy and fast.
The GT version I mentioned has the black chili compound, like the 4000
GP5000 tubeless here as well. Rode them on last year's Paris Roubaix and they were superb. The tubeless works so well (dedicated Shimano wheels so no ghetto) and is noticeably faster and smoother than the Hutchinson 25s that they replaced. I had never thought that they would roll better and faster , but they were a revelation.
