Perhaps itï¿½s a defective tire - the front is looking good, but the rear is losing a significant piece of rubber right in the center of the tread. They were easy to get on, seal and have been great up until now. Didnï¿½t even need a special pump or my compressor - just a normal bike pump and the beads popped right on. Wish I could find them in stock somewhere; but might have to look at another brand and/or site. Supply chains seem to be a problem everywhere right now.
Previously I rode the GP 5000 tubed version and the GP 4000 before that. I had good experiences with both and got good mileage, low rolling resistance and good handling.
I had bought a pair of GP 5000 TL 700x32 and had been saving them for when the GP 5000 tubed version wore out. Recently I decided not to wait any longer and mounted them to my Belgian Plus rims. Using my Kool Stop Tire Bead Jack and a little soapy water, the tires popped right on. I usually use a Schwalbe Tire Booster for tubeless but decided to try my old floor pump first. Surprisingly the tire started inflating immediately without sealant and held pressure at 75psi. I opened the valve stem and added some Orange Seal and I'm done.
So far the tires are great and at least as nice as the GP5000 with latex tubes. I'm looking forward to working out the tire pressures and getting some longer rides in. Mine measure just under 33mm on the Belgium Plus rims. My GP 5000 tubed grew to about 34mm.
After 1,200 miles on this most recent set of tires. Most of the miles have been over the winter and this spring, lots of debris on the side of the roads. I can't tell you how many people I have passed on the side of the road fixing flats, not me. These Continental Grand Prix 5000 TL Road Tires do not get flats. I used to be that guy, I'd get 4 or 5 flats a year. After getting ENVE 3.4 tubeless rims and these Continental Grand Prix 5000 TL Road Tires (I ran the 4000's before these) I haven't had a flat in over two years and 12,000 miles. The ride is more compliant and the handling is the best.
I've tried multiple brands of tubeless or tubeless ready tires and mounting them and getting them to seal can be very frustrating-not so with the Continental Grand Prix 5000 TL. I've mounted 6 of them on various bikes and they have sealed & inflated every time the first time that I tried. Perhaps not quite as cushioned as other brands but their resistance to flats is excellent. They also seem to be more long-wearing than many of the other TL or TLR brands. Grip is also excellent! It's the best tubeless I've encountered so far!
My bike came with the GP4000 which were great tires but mounted wider than marked width. These updated 5000 are just as great and in my experience mount truer to marked width. I'm running the 32s at 65-72PSI and I'm 220LBS. They definitely wear out quick running them that low but running tubless at the pressure makes the ride relatively plush. I like to experiment with different tires and have branched out to different brands, nothing is as consistently "good".
Have been riding road tubeless for 10+ years. After trying Hutchinson, Schwalbe, Vittoria, and a few others, nothing, absolutely nothing, compares to the durability, ride quality, and mileage these tires provide. Other tires can be slightly more supple, such as the Schwalbe and Vittoria, but the Continental 5000 TL have given me far greater puncture protection and 3 times the mileage as any of the other's at least 2500 to 3000 miles of dependable riding on average to very poor and rough road conditions (I average 800-900 miles per month). Not the lightest tire, nor the cheapest, and their popularity has made them difficult to find in stock from time to time. If you want a great performing durable and long lasting road tubeless tire, you should seriously consider this tire.
Fitted 2019 Continental Grand Prix 5000 TL Road Tires to Bontrager Aeolus 2 tubeless ready rims. 28 mm. Went on with no problems, just a little lever action at the end. Seated well with no issues. I use an air compressor but imagine a hand pump would have done the trick. Used Orange sealant and no leaks. Holds air well. Roles smooth and corners fine. Holding up with 400 miles ridden so far under road conditions with lots of debris due to FallWinter season. No real cuts or abnormal wear. I run at about 65 psi but am not a lightweight.
Tires are awesome, they are wearing down a bit quickly, I've put around 800 miles on them and the rear tire is getting a bit flat on the contact surface, I've seen 4 and 3 small punctures on the tires respectively it is unsure if they made it all the way in as I have not seen a significant decrease in tire pressure. The tires do drop 10-15 psi every 2-3 days, I'm inflating them to 100psi and using stans racing sealant. This tire does it seem to have a lot of life, the wear dimples seem pretty shallow. Lastly these tires were difficult to install. Overall a great tire, only time will tell how they wear vs what I've seen.
Ordered a few months ago and finally needed to mount the tire on the rear, which proved to be nearly impossible. Finally took it to my LBS who is a very big, strong guy with special tools who had to use almost superhuman effort to get the beads on the Mavic Cosmic UST carbon wheel. Now have only about 100 miles on and seems to perform very well but I will not be buying this tire again. There is no chance I would be able to put in a tube at the roadside if it does flat. Really like the tubeless system and the Mavic Yksion Pro that came with the wheelset performed very well for 5500 miles.
1 - these tires set up tubeless on HED Belgium rims very easily. Virtually no swearing at all involved. Seal with floor pump. Have kept air pressure very well and although under 500 miles of use, no leaks or flats
2 - the ride is very comfortable and confidence when braking and turning is unmatched except with my tubed version on another bike
I ran Continental 4000S for years, so it made sense to upgrade to the 5000. Tubeless tires offer superior handling especially on fast, tight descents, and the 28s allow you to ride confidently over cracks, potholes, and chip and seal. However, I was stunned the day I ran over a sharp piece of cable, about 6 cm long. Half of it was embedded in the tire. I had just started the ride, so I pulled out the piece of cable, rubbed the leaking sealant over the hole until it stopped bubbling, and went on to finish my 50-mile ride without issue.
I could not get these Continental Grand Prix 5000 TL 32C tires to fit on my rims - Roval CLX 32 Disc. My previous tires (Specialized Turbo Cottons) fit easily without tire levers but these were impossible. If I'm on the road and get a puncture there's no way I'd want mess with this tire, it's got to be easy enough to get on and off on the roadside.
I only have a few hundred miles on these tires but, so far, I'm very happy with them. They were pretty easy to mount on my Enve rims, ride nicely at about 75 - 80 psi, hold air really well and after only a few hundred miles I haven't had a single flat. There aren't even any detectable nicks in the rubber. This is the opposite of my experience with some other tubeless tires I had which were lighter and had a slightly better ride but were not very cut resistant.
Made the switch to tubeless about a year ago with these and was not disappointed. Fast rolling and NO flats. The rear tire went 3200 miles before showing casing; I've changed it out. The original front tire is still going with the dimple wear marks looking fine. Overall: fast, grippy, & a bit stiff, but no complaints since no flats.
This is my first attempt at road tubeless. I initially ordered the Schwalbe Pro One TL cancelled my order after seeing more favorable reviews on this tire. I tried all the tricks I saw in YouTube to mount and still had a challenge. There's no way I could stuff a tube in these tires if I had a flat in the road that didn't seal. I am having to fill these up every 2-3 days despite having sealant but this might be part of the cons with tubeless road tires. I lose about 5 psi every day. On road performance has been good, just what is expect for GP5000s
Bought my second GP 5000 TL tire after a huge staple took my last one out. Had about 500ish miles on the last one but a staple double pierced the tire and actually punctured the side wall from the inside. Stans tire sealant couldnt seal the side wall and didnt trust it enough to try and patch up or something. Considered buying a non tubeless because the current selection of TL tires isnt as large, we are currently heading into winter so almost got some Gator Skins, and these tires are SUPER hard to mount.
GOOD: The tires ride well and besides the staple I never had issues with leaks or punctures.
BAD: Hard to mount on rim, possibly not quite as puncture resistant as I would like.
I use the 5000 TL 28s on my road bike and Bontrager XXX 4 wheels, (Domane SL). A little difficult to install, stretching the final bit, and worth the effort. I'm using Orange Seal and the punctures I have received, construction staples, sealed quickly allowing me to continue my rides. I ride in Central Oregon and this setup smooths out the ride and allows me to descend at speed, with confidence. Instead of pointing out the gravel at intersections we can ride right through. No loss of speed in the pace line and I'm getting PRs over my previous tube setup (28s) and previous 25s on my former bike. I'm getting 1500 miles on the rear tire with 75 pounds of pressure. I changed the front at about 2K miles. My wife, much lighter 135 vs my 199 pounds, is using 70 pounds of pressure front and back. I found I needed the extra pressure due to my torque on the wheels, and my massive thighs causing the brake rotors to rub at 70 pounds. I use 72 pounds in the front tire for the same reasons.
I was hesitant to trust tubeless on the road but it's been pretty bomb proof. One puncture that wouldn't seal (a slice, really) in over 10K km of riding. Those are far better results than I expected. I feel like these wore more quickly than the 4000/4000s clinchers I've used the past few seasons, but I'll trade that for the dependability, traction and overall excellent performance. Mounting these on my ENVE 5.6 rims was brutal. So much so that when I sliced that tire, I took it to a shop to install the new one (and, while they did it in about 15 mins, they commented that it was really tough to do). So 5 stars for riding performance minus a star for being so tough to mount.
Bought a set and mounted them on Hed Ardennes in March. Struggled a little getting them on but they pump right up because the tight fit makes a good seal. Had to replace the rear tire due to a sidewall tear in June. Front tire lasted all summer >4000 miles! Overall I love these tubeless tires for relative ease of use, plush ride at correct psi, grippy in corners, and durability.
Pro tip - leave in direct sunlight for 20 minutes prior to mounting.
I heard these were hard to mount...on the contrary, I did it with a floor pump. I don't have many miles on them yet, but hope they will last. Seem to be smooth rolling and fairly sticky. I initially got the 32mm, but they would not clear my front fork, something to keep in mind if your bike is a few years old (mine 2016). These are perfect though. I might have been able to go with a 27mm, but knew the 25mm would work. Fast return of the ones that did not fit and credit.
