Second pair of these tyres that I have owned. Others still going strong but on a different wheelset. I believe I have only had one puncture so far after a few thousand miles (fingers crossed) so had to buy the same for my new wheelset. Great grip on the road including when it is wet. Can only highly recommend them.Great service and price from Sigma Sports and delivery was spot on.

After battling for about 8 months with the 32c Gravel Kings and clocking up double digit punctures I switched to these guys. Easy to fit and feel super smooth and speedy on rough roads and light trail. Not suitable for gravel but perfect for winter riding and slightly gnarly uk roads. So far no punctures though it’s only been a month.

I bought two of this tyre as my winter setup to replace my GP5000STR tyres which were getting sliced on our lovely UK roads currently covered in grit.I had to return one for warranty replacement as it had a really uneven sidewall that was noticeably wobbly looking when spinning the wheel. The replacement is pretty much perfect. Thanks Sigma for sorting that.HOWEVER the other tyre is cursed. I have been on 3 short rides (~20km each) and each one I have had a problem after or during the ride.After the first ride the tyre was flat morning after but no punctures at all. I was using Conti Supersonic tubes which are stupidly thin, but light. The particular tube I used was leaking air all over when pumped up to pressure. I submerged my wheel under water and you could ... MoreI bought two of this tyre as my winter setup to replace my GP5000STR tyres which were getting sliced on our lovely UK roads currently covered in grit.I had to return one for warranty replacement as it had a really uneven sidewall that was noticeably wobbly looking when spinning the wheel.

I was using Conti Supersonic tubes which are stupidly thin, but light. The particular tube I used was leaking air all over when pumped up to pressure. I submerged my wheel under water and you could see water coming out the beads. But taking the tube out and putting in some air to submerge under water, I could not find any puncture holes. I ditched that tube and used another new same tube which seemed to hold pressure fine.Second ride, PUNCTURE. I must have went over something sharp that put a 5mm cut straight through the tyre completely and cut the tube. I was 6km out and walking home in cycling shoes wasn't fun. I patched the hole in the tyre with Rema universal patch and SC-BL cement, otherwise it's a £36 write off after 2 rides. Also swapped over to some tubes from Decathlon, they were cheap but almost 2.5x heavier at 120g but for the sake of 140g overall I didn't care.Third ride, 20km and got home fine. Next morning, FLAT TYRE. Again, no punctures in the tyre and definitely no air leaking out the hole I patched. Taking the tube out and submerging it in water revealed some strange cut lines exactly where I patched the tyre. What caused it? The layer of plastic on the patch that I forgot to peel off had bundled up when the tyre was mounted, then combined with the tube at 60psi, the bundled up layer of plastic turned into a knife edge and cut into the tube creating a tiny little hole which lost air overnight.So currently I'm on my fourth tube, 1 faulty, 2 punctures and a cut flap on my tyre. I'm not impressed, but the other tyre had been perfect... If I wake up tomorrow and the tyre is flat without riding the bike, or the next ride I get another puncture I'm switching back to my GP5000STR tyres and tubeless. I've used them for around a few hundred km and have only had 1 tiny puncture where it didn't seal properly as the sealant inside the tyre was basically dry.From my current experience, out of 2 samples I would not be using these tyres again once if they puncture on my next ride!

700 X 32 Continental Grand Prix 4 SeasonThese are great tyres. I had 6 punctures in the first week with the original Maxxis tyres that came with my bike but since fitting the Continentals I rarely get flats and the causes of those flats, no tyre would have withstood. I replaced the rear Continental at about 21,000km and the front tyre, though looking a bit ratty, is still going at 32,000km.I run these with tubes and without sealant goo and cannot speak too highly of them.
I use these in 32mm on a Dean Ti all-road bike riding in and around Baltimore. I currently have about 3,400 miles on the set and they are still going strong, reflecting only minor wear on the rear tire. The sidewalls and beads are still perfect.I've never had a flat on these tires (knock on wood), and yet they are fast for a durable set of tires and durable for tires that are this high performance.I would compare their performance to the superb Schwalbe Marathon Supremes, which in the U.S. are way more expensive than the Conti Gran Prix All Seasons.
Bought these about 2 months ago during the cold spell. Managed to get a few rides in to test them. They are definitely a harder tyre compared to my Vittoria Corsa 2.0, but they have great grip in our UK damp roads, and they handle the pot holes much better than a softer tyre. I still run all my tyres with tubes, keeping the psi at 95 rear and 92 front I found these very comfortable on our non perfect roads. They have a really good rolling resistance, comparing them to my Vittoria, doing exactly the same route, I lost about 1mph on my average pace, that could simply be due much colder weather on the previous ride I compared to, but for me, getting out in winter and having the extra grip on wet debris from the rain, is more important than going like a bat out if hell. ... MoreBought these about 2 months ago during the cold spell.

They were easy enough to fit, I had no issues fitting them for the first time. As for punctures, nothing is puncture proof, so time will tell. Yep, loving the new shoes on my bike.
As soon as I went from 30 mm Espoir tires to 32mm Continental Grand Prix 4 tires, I instantly noticed high level of comfort when riding. It has made lot of difference since this rubber compound soft yet it is thicker for puncture protection. Time will tell if it hold against the small punctures. So far ride is amazing and I don't think it is heavy or have to put more effort to ride. Ride is smooth and comfortable. And tire sidewall has a dark maroon color, looks beautiful. Get this color instead of all black version. Go 32mm and you will not regret.
But soon to comment on these in terms of puncture protection. I've not had any punctures so far, but I'd only had one in the preceding 9 months anyway.What I can say is that for a supposedly beefier tyre, these roll very smoothly, and they seem to soak up a lot of vibration and jarring. I'm not exactly racing crits on these, but so far I've not felt any problems with their grip even in very bad weather, including having to cross paint on relatively steep climbs where I was really expecting the back wheel to slip.
I've been running 4 Seasons on most of my bikes for years, occasionally (but not always) changing to lighter/faster options in the summer. They're quick enough for me, as well as being reasonably light and dependably grippy. Most importantly, they're tough. I don't know why I'm sharing this because sod's law dictates that as soon as I've put this out there I will get a puncture per day for the rest of the year, but I went for a full year (ca 8,000km) on a pair of 28c 4 Seasons without a single puncture - and that included some very cruddy winter roads. I'm now running the 32Cs on my winter bike at about 55psi and they're ridiculously comfortable. Highly recommended.
The best 23c tyres I have found. Went over 12 months riding British roads and through a city centre covered in broken glass without a puncture.They're tough, puncture resistant and still fast. They grip the road well in bad weather.Very fast delivery from Sigma Sports as always!
