I got these in 28mm and mounted them on HED Ardennes LT+ TR rim brake rims (21mm interior width). Replaced a set of tubed GP4000s. Like other commenters note, the 28mm tubeless look like my former 25mm tubed tires, but I haven't measured them. I didn't have any trouble mounting these, though I used tire levers to mount them. They're a pleasure to ride; tubeless is always a little plusher than tubed, but these are a bit silkier than other tubeless I've ridden. It may be my imagination but they seem a little faster than my previous GPs. I've ridden about 300 miles on them over all kinds of surface, including milled asphalt, crappy NYC streets, and dirt, and I've had no flats and no premature wear. Expensive but I expect to get every penny out of them.
I just made the transition to tubeless and really like these tires! They were one of the lighter options I looked at and I enjoy the ride with them! They feel super compliant and have great grip, they roll really well and have been very durable so far. I had read that some folks have difficulty mounting them them but I fortunately did not. Once they were on the rims I was able to inflate them using a standard floor pump! They are a super sweet tire!
The previous generation was an excellent tire; the latest generation is even better. It is more supple and grippier, and the overall ride quality is improved. They are still difficult to mount on tubeless rims, but that's largely true of all road tubeless tires in narrow widths like 25mm. I got about 3,400 miles out of my previous set with no flats before they started looking dry and stiff. I suspect I will get even more longevity out of these.
I love the normal version of the GP5000. With my new hookless rim, I had to go to the TR version. It seems like a lot of money for a bike tire. So I tried the Pirelli P-Zero and a Michelin Power Cup TR. The Pzero lasted one 25 mile ride, then got a 1 inch slice all the way through the tire after running over some glass the next day. I have never seen any of my GP5000's do that. The Michelin lasted a bit longer, but still did not seem as puncture resistant as the GP5000 TR. I'm done testing other brands, and will just stick with my tried and true GP5000. They are worth the cost, and get less flats than most all of my riding buddies. Worth a little extra money for the peace of mind.
I've been using these on the road in 32mm, 30 mm and 28 mm. These used to be great tires but puncture resistance is now abysmal. Pinhole punctures that seal on other tires just don't on these and they can't be inflated to the right pressure.
This is not a single experience. It's happened for a few years in multiple sizes. Meanwhile, I've ridden a pair of Strade Bianca handmade clinchers on my gravel bike for over 2 years and they're covered with pinhole punctures that sealed.
I've been riding Continentals for 15 years, but I'm done. There are faster tires with better road feel, if you don't care about puncture resistance. They GP 5000 ASs may be more reliable, but I just don't feel like supporting this brand anymore.
I've been using Continental GP5000's for about a year and a half now, first 28mm and now 32mm.
These tires are great due to their excellent rolling resistance properties, have bettered my lap times just by changing to these tires. They can handle some form of compact, easy gravel but most of the time I ride on road.
Seating them on the rim is always the hardest part but I've put on and taken off about 8 pairs now for myself, and for 5 different rims and for other people. They inflate up easily all the time.
Love them and will continue riding them all year round (including wet springs and cold winters).
It has been a while since I last used continental tires. I wish I would have switched back a long time ago. These tires live up to the hype. I feel at one carving and descending unlike the other brand I was currently using. 10/10
Bought a set as spares/future tires after the second set of Challenge PRO Strada's wore off. My bike came with the Challenges and I loved them! Absolutely the supplest tire I have EVER ridden. Got 1,000-ish miles on them before all the fibers started fraying on the sidewalls. I had bought a spare set of those despite all the reviews of the impossible difficulty in mounting them simply because of the ride quality; after spending a little over an hour to mount each tire(!) and that after trying all the tricks, I was rewarded with the sublime ride and a tread cut ON THE FIRST RIDE. So I ordered a set of Conti 5000S TRs. Put them on this last weekend and rode them for the first time today (27 July). Impressions below:
1. EASY to mount; 700x30 tire on Astral Radiant wheels; a little less than an hour to install BOTH tires
2. Lose a little air overnight; same as the Challenge tires
3. Maximum pressure is 73 psi vice the 65 psi on the Challenge; a little more room to try higher pressures for the big/fat rider
4. At 66 psi front and rear, the ride is very very good. It is not sublime like the Challenges. It is compliant and solid, but nowhere near as supple (that was expected)
5. (Hopefully) longer wearing; I am used to getting anywhere between 3K and 5K miles out of the Gatorskins with the tubes inside; rotate the tires=get more miles
6. Price is a virtual tie
I think I may give the Schwalbe Pro ONE TLEs a try, too
What more is there really to say about what is arguably the "Gold Standard" in road tires? My 3rd set on Canyon Aeroad, now trying 28F / 30R with this new set, vs. two prior sets of 25F / 28R, running ~ 73 psi F / 76 psi R. Seem to clock right at 4K miles each set, when the wear dimples have faded away. A bit of a bugger to mount on deep-section carbon rims, but do-able. Confident handling & cornering, reasonable ride comfort, too.
These tires mount pretty easy to the rim and seal up very nicely even without sealant. I've even gone a few days after mounting the tire before I add sealant, and the tires still hold pressure very well ( only losing a couple PSI). On the road they are great to ride, supple, fast, and responsive.
The GP5000 S TR tires have performed well. The wear has been good, while traction, ride and speed are 2nd to none. Tires are easy on/easy off of carbon rims. While I have been running these tires with TPU Tubes, I'm sure the tubeless performance is flawless, as well
I am riding on the 32mm wide version of this tire on Zipp Firecrest 303 wheels (25mm inner diameter) at 50/52 psi F/R. I weigh 185 lbs. They are both wearing well after 1500 miles use. The front tire still shows a trace of the casting seam in the middle of the contact surface, but not the back. Wear dimples are still visible on both tires. I have only found two tiny nicks from road trash in the contact patch of the rear tire. Sidewalls are in pristine condition. They roll very well and are extremely comfortable. I thought I was on a new bike after replacing 28mm tubed Conti GP5000 S tires on Mavic rims with 17mm ID. I expect the front tire to last for over 6,000 miles, perhaps much more. One of my Conti GP5000 S tubed 28mm tires lasted 10,000 miles before I replaced it. I have front and back ones still rolling with 8400 miles. I hope to get similar life out of these tubeless ready tires.
Great tire! Sets up nicely with tubeless and its combination of speed and puncture resistance that can't be beat!
This is my first time using the GP 5000 S TR, and right out of the packaging, these tires are super impressive. They a supple, which made installation easy and effortless. I was able to get them seated on my carbon rims with a floor pump. I'm a novice mechanic at best, and it took me less than 30 minutes to get them installed, filled with sealant, and out on the road. That's a win for me. The ride is plush and I feel like I'm on rails when entering turns at speed. Really impressed with these tires. Aesthetically, they look fantastic, too.
Bought black 30cs for aesthetics and speed.
I've been using GP5000STR 32c and Corsa Pro 30c. GP5ks are much more reliable and puncture-resistant. Although crosa pros do have a better road feel and the side walls look nice, I go back to GP5Ks just want to deal with maintenance less. Also when you want a full black tire there is the option available from Conti.
Great tires! According to Bicycle Rolling Resistance they are very good, and at a price that isn't astronomical they are a great value. I use them on my road bike and live on a dirt road so they are ridden on dirt just about every day. I rarely get punctures and they last a long time.
Fast pace group rides.
Have been using these and the previous model for years now. For me the overall feel is what I like best. Connected to the road but very supple. I seem to get about one flat a year with these and most of the time the sealant keeps the tire from going flat. They do not last as long as some harder tires but the handling and feel are well worth it. I now run about 90psi in the back and 85 up front in the 25s. I get almost two to one on changes front to back.
It may just be psychosomatic, but I swear these tires added a mile an hour to my average times. Love the ride quality. They're excellent in the rain when it's wet. I've been running Stan's slime in them and haven't had a flat yet. Plenty of holes that have self patched while riding.
The tubeless journey started with the MTB tires and then I tried the road tires. This new version of the Grand Prix is superb. I have acquired the appropriate tools and I can now change this tire in my garage in 5-10 minutes. Check out the Park Tool wheel block, it makes it much easier to get the needed leverage. I have been using Orange Seal Endurance without incident. The occasional puncture gives off a little spray and then seals. I'm talking 4k miles this year without a ride ending flat. I ride in Central Oregon on chip seal and on local mountain roads with debris and pot holes and snow plow gouges. I continue to lower the pressure on the tires until this year 64 front and 70 rear. I'm 189 pounds and this has significantly softened the ride.
The tires are great. For a point of reference, I ride them on a Canyon Endurace - carbon fiber frame, aluminum wheels and Di2 drivetrain. 700x28. They are fast but, still smooth. A more comfortable ride than Gatorskins. They're very grippy. I'm taking corners and descending with these like perhaps and old man shouldn't. I did over time end up with gashes that wouldn't seal and had tubes in both tires before the wear indicators were all the way down. It's my third set so, I definitely like them. I weigh 210 lbs (95ish kg) and they last me 1500 to 2000 miles.
