I have put about 1000 mi on these on mostly tarmac, with fair amount of rough roads and some splintery wood plank bridges. Running tubeless and can compare to tubeless Conti GP5000 S (32) and Conti GP5000 (28), on which I put 1000's of mi in similar conditions. These are all fabulous smooth running tires on which I had only 1 flat ' sidewall cut on the 5000 S. One major difference between the AS and those other 5000's: They would all get minor cuts that would seep sealant at very low rates ' not a problem at all, but occurred consistently. This has not happened at all on the AS's, apparently due to the greater reinforcement (ply's). Because of that reinforcement, the AS's are not as kush as the S's, until you run them at 2-3 psi less pressure, which works for me. So these are great tires: smooth, durable, and noticeably a bit more sticky than the other 5000's.
I was having lots of punctures with city riding on the GP5k S TR in the rain (3 sets in 4 months, all in the wet), picking up lots of grit and causing large, unfixable gashes. Switched to the AS TR in the same size, and after 500miles they're holding up strong.
Wet grip seems on par with the S TR, dry grip slightly worse. They feel slower than the S TR, but it's a worthy compromise for my winter riding.
So far, these tires have lived up to the hype. I ride in a metro area and you learn very quickly if a tire punctures easily. These do not. They are not affected by glass and small debris like true race tires are. Puncture protection is very good.
The tread is thick. Obviously. Very comparable to Pirelli P Zero Race.
For me, it's perfect. Won't puncture easily and is still as fast as anything else.
Because the tire is so thick, it doesn't have that 'supple' feeling like a Corsa Pro. However, I ride on crap roads and chip seal. So I actually prefer a thicker tread that dampens the chatter.
I managed to install a pair 700cx35 on my 2022 Specialized Roubaix Comp and it turned into a super comfortable endurance bike.. even more comfortable than it already was. At 215 lbs, i was able to run the rear tires at 58psi and front at 55psi and they absolutely soaked up the small bumps and ruts i would ride over. Did not feel any penalty in the speed department as i regularly approach even beat my PR's from previously ridden routes. Very happy! I will look into buying the cream walled version next time to add some style points.
2023 TREK Emonda SL7 came on tubeless ready carbon rims but had tubes and non-tubeless rated tires. Switched it early to Conti 4 Seasons (25mm) with tubes and 85psi. After 3K miles did the tubeless upgrade with TREK rim strips and Conti 5K ASTR. ASTR seemed to be the closest tubeless compatible product to the 4Seasons I have used for years. 28mm tires with 70 psi (I'm a 200 lb pretender) improved the bike dramatically. Slightly faster, noticeably smoother but mostly the previously chatter prone frame became silent on all but the biggest hits. Have another 2K with the tubeless and am very near the wear indicators on the rear. Maybe a little disappointed in wear rate at this price point but will continue to support this product. My conclusion is that the bike should have shipped with tubeless and without experiencing other brands/models the ASTR is perfect.
These replaced a well-worn set of Gator Hardshells on my winter setup and they are a noticeable upgrade in ride quality. Much faster, better wet grip, and far more supple over rough road. No flats yet with about 250 miles running butyl tubes.
Bought these to replace some gravel tires because i really did not ride that much gravel. They track and grip perfectly on the corners.
Gravel tires tend to squeegee/squish when you go through turn which can be a bit tricky.
Have had these on the road bike for a few weeks. Replaced Conti GP4000 4 Seasons. The GP5000 seems quite a bit faster, and grippier. Been riding in the rain with a lot of confidence. Can't comment yet on puncture resistance or longevity. Mounted on Enve M50s - tight to get on, seated with floor pump + storage / release chamber.
I am almost through a 35-day cross-country tour. 110 miles per day. I swapped to these new, tougher Conti 5000 tubeless after wearing out a set of Schwalbe Pro One tubeless. I have never had any piece of bike tech make as much of a difference to my performance. They are dramatically more comfortable and faster. They also installed easily on my notoriously difficult Zipp 303 hookless rims. I can install myself with arthritic hands, without a tire jack. I love these tires!
I ordered these tires a few times. All around the best tires I have ever owned. They last a long time, and I have not had a flat with them yet. They grip well throughout their life span. They can be hard to put on my rims, but it's the nature of the beast for me.
I'm trying these as a replacement for the GP 5000 S TR I started with. The S TR only got 3300 mi / 5300 km before being worn out, barely 6 months of riding. The AS version is a much tougher version. I've got only a few hunder miles / km on them, so I've no indication, yet, if they are longer wearing, but I am very pleased with the handling of this tire. Corners like the racing version, grips like the racing version, but the feel is much stiffer. At 10-15 psi less than I used to carry, the bumps are still noticeable. Previously, I used about 70 psi, and I'm now down to 55 - 60 psi.
The stiffness of the ride is due to the increased tread thickness. This is also supposed to provide more puncture resistance, but I'm hoping just to get a full year out of these tires. Using Silca Ultimate Tubeless Sealant, I never noticed if I had any punctures, so the puncture resistance is not an issue for me. Only time, and distance, will tell if this change was worth it.
I have installed many TLR tires before, but this was my first time trying GP5000. It was indeed nicely built. The only problem I have is, it is slightly not true. Not sure what's going on. My wheels are true. I tried to remove it and then re-install it, but it didn't solve the issue. It feels 'bumpy' at the same location. I don't think it is my skill. Might be a QC issue.
Performs the same as a regular gp5000tr as far as traction/handling in dry weather but slightly heavier and thicker which helps with comfort and durability. It absorbs vibrations slightly better than the regular lighter version. I found that the thicker tire is also less prone to deforming when your rotate tires frequently between rims which helps with easy inflation. Unfortunately I ended up flatting my 28mm about 300 miles in on a massive m8 wood screw. Patched it up but the tire would inflate with a slight hump where the puncture was which pretty much made it useless. Overall it is a great tire that performs just as good as previous models but with added comfort, durability, and reliability but is not invincible. The extra weight is not noticeable. Great for daily use but I wouldn't mind racing on them.
Rode these twice in the rain, wet roads, and found them to be very grippy. Much better than Goodyear and Schwable I had on these rims before. Even pushing pretty hard into corners on wet road I have a great deal of confidence with these tires. I'm 175-180 lbs, and I ran them at 45 psi on wet, vs 50psi for dry roads.
Also raced two criteriums with these tires and they worked fine. Probably not the lightest race-day tire you can get, but good enough for me (Cat 4).
Perform well, mount easy & roll without effort.
Great rear tire, a little more puncture resistance versus the S TR. Get it on sale.
After many years working in a bike shop, I have a longstanding hatred for Continental tires because they are traditionally so tight. BUT, I broke down and tried these as there are very few options for my rims, Giant SLR2 carbon hookless. They were super easy to mount, no problem, and sealed right away.
Out of the package they feel a little more substantial than Schwable Pro One, but not quite as heavy as Goodyear Eagle F1s that I have run on this bike. Roll seems really good and they are very grippy, at least on dry pavement. Only had them one week, but if they're as durable as the ad says, they could be my go-to for training and racing. Pleasantly surprised.
Was able to get 28mm on without much struggle then easily use regular hand pump with small amount of stans, hooked SLR giant wheels. Handles great on steep descent. Had been happy with the durability of Maxxis, these appear at least as durable.
I put these on my road bike that is tubeless ready. Great tires. Long lasting with grip. I will sometimes ride lite gravel and dirt on them.
Low rolling resistance that I could feel
with excellent confidence inspiring grip and durability. So far I've had about 200 miles on these. No cuts or punctures (knock on wood)
