Continental Grand Prix 5000 700C Transparent

ORDER DATE: 01/05/2020ORDER NUMBER: X1761130I bought a continental GP5000 tire as a continuation of the great satisfaction from the continental GP4000 ii, reading the excellent reviews, to use it as a rear tire. I ordered them in May, I was late to receive them due to covid and I finally placed it in early July. Unfortunately in a very short time and with minimal use, 500 kilometers, the product in a routine walk on asphalt was torn to the side and unfortunately destroyed.There are no guarantees for the tires as I understood after contacting continental. My company replied "The damage to your tire has been caused by sharp road debris and is not a manufacturing defect. Unfortunately this is just bad luck "showing clearly that a material failure in one of the ... MoreORDER DATE: 01/05/2020ORDER NUMBER: X1761130I bought a continental GP5000 tire as a continuation of the great satisfaction from the continental GP4000 ii, reading the excellent reviews, to use it as a rear tire.

My company replied "The damage to your tire has been caused by sharp road debris and is not a manufacturing defect. Unfortunately this is just bad luck "showing clearly that a material failure in one of the most critical parts of the bike for safety is due to misfortune and that its responsibility is limited to selling expensive and well-publicized tires that are torn sideways" by the wind " .Sigmasport was initially offered to offer me a tire at a better price. In the first choice I made "vittoria rubino" he offered me a price much higher than the competition, which he improved after a market research I did but not satisfactorily. In a second proposal I made for the continental GP5000, thinking that I would have a more favorable price on the tire that was damaged, the OFFER was 8 euros more expensive than the competition per tire with free shipping. I preferred to buy 2 tires from another store with 5 euros shipping. Unfortunately my opinion on sigmasports, in terms of customer response after purchase, is not the best (read also my experience with ENDURAFS260 PRO BIB SHORT shorts).I'm really unlucky with orders from sigmasports.In summary, I believe that the continental GP5000 Folding tire is an expensive, very good tire with a big problem on the side walls. Searching the web, you will find many bad reviews in this area. If you want a safe tire above all, choose something else.

GP 5000. The gold standard for road bike tires. They certainly live up to the hype. I found them to be extremely fast on asphalt. They glide on black top road like warm butter on toast. On chip seal, they are okay. They corner so beautifully that I found myself being reckless on turns. That's how much i trusted the grip.Only negative, and its a big one. They wear out so fast. I got about 2622.5 km out of my rear tire and about the same from the front tire. The rear tire was squared, the indicator dimples all but gone and the front developed a slight bulge. I should also mention that i never once had a puncture with these for the 2600 or so kms. I rode 25 mm, that were always pumped to >110 psi.You pay a premium for these and they certainly deliver in the ... MoreGP 5000. The gold standard for road bike tires.

Just keep in mind that soft racey tires are not going to last long.

I bought these tyres to go on a new set of DT Swiss ARC1400 tubeless ready rims. The wheel manufacturers recommended 25mm tyres to go onto a rim with 17mm internal width. Having used standard GP5000s with tubes for the last few years on a pair of Mavic rims they were the obvious choice for the tubeless upgrade despite reading the reviews that they are nigh on impossible to get onto the DT Swiss rims! Surely they couldn’t be that difficult to fit? Well, I can confirm that after an almighty battle, two grown men (after calling on a friend for assistance!) against a simple rubber hoop, skinned knuckles, some pretty ripe language and numerous snapped tyre levers these tyres do fit the rims perfectly. Possibly too perfectly hence the difficulty mounting them in the first ... MoreI bought these tyres to go on a new set of DT Swiss ARC1400 tubeless ready rims.

Well, I can confirm that after an almighty battle, two grown men (after calling on a friend for assistance!) against a simple rubber hoop, skinned knuckles, some pretty ripe language and numerous snapped tyre levers these tyres do fit the rims perfectly. Possibly too perfectly hence the difficulty mounting them in the first place. Once on the rim though they popped into place nicely with a quick blast from an air compressor, first time, even managing to get the logos lined up correctly with the wheels. The tyres actually measure the quoted 25mm once fitted and inflated so they look super slick on the rims. No unsightly balloon look or under sized stretched appearance. Once seated and the Continental sealant added they have kept pressure brilliantly. They roll beautifully and the grip gives confidence turning into high speed corners. Worth the struggle getting them on and I’m now just praying they don’t need to come off for some reason any time soon! Tubeless puncture kit and CO2 adapter also purchased as I certainly don’t fancy having to insert a tube on the roadside in the case of a puncture!
