Have ridden GPs for 25 years. The best all round tyre !! I keep trying other tyres for shits and giggles. But always come back to GPs, other tyres just don't have the robustness as the GPs. Although I do love the feel and speed of the Corsas !!
Very well done review. On the actual tyre width, it is worth mentioning the rim inner width, which determines the actual value. Silca calculator doesn't take into account the different rim widths, which has an impact on tyre pressure. Sram calculator doesn't it.
I also used to use the older Corse/ Corsa Speed TLR. Also loved them and also had the same issues. Then I switched to the new Corsa Pro TLR. Game changer!!!! Installs without levers. Seat easier. Did you consider these?
I did consider going with the Corsa Pro over the GP5000 S TR. Like you were saying yourself, other riders have also been commenting that this new version is much easier to mount. I knew it would be a fast rolling tire, but my concern was its wear-rate and how easily it would puncture. The Corsa Pros don't get a great puncture resistance score on the Bicycle Rolling Resistance website, and I had heard some reviewers complaining that they were a bit delicate. How would you rate these tires for puncture protection as compared to the Corsa Speeds? Thanks for your comments as it does throw another tire option into the mix. I may consider going back to Vittoria and trying the Corsa Pro TLR if I can just shake the bad experience I had with the Corsa Speeds :)
I've been on str's for over two years ... fast and grippy with excellent durability. I use them year round for all types of riding. Road feel and suppleness is very good for me but I run them on hookless zipp wheels at much lower pressures and I'm around 61kg. Also, the wide inner rim diameter of those wheels does quite markedly increase the tyre diameter. Sealant choice important too ... sweet spot allowing rapid puncture sealing but not too thick, blocking valves or drying up too quickly etc ... I use Fibrelink by Finish Line for those qualities.
I have switched to TPU tubes, from rubber tubes, far better performance. Still not sold on tubeless with road tires, although I use tubeless on my mountain tires. I will try Vittoria for my next road tires. For me the key to success for TPU tubes is to use tubeless tape to cover the spoke holes, I use 2 wraps.
It is such an easier decision to go tubeless for mountain bike tires. A lot of the blame for road tubeless has to be put on many of the manufacturers of poor tubeless products. Tires and rims not built to tight tolerances. Valves that don't fit snug enough to be air tight. And, tubeless sealant makers. Any sealant that can be filled through a tubeless valve (which is most of the ones sold) is pretty much useless. Latex sealant without any additional particles won't plug anything larger than a pin hole. Silca Ultimate Tubeless Sealant is the only one I've tried that works consistently at tire pressures over 70 psi.
I agree Silca is pretty much the only sealant worth trying. Still see no advantages of tubeless over TPU Tubes for road bikes. TPU only losses 300 mW, which is so close to 0 in practical terms, and is lighter than the sealant as well.@@bikesbymike
i rode GP4000 for years but they became a snitch to install on tubed tires with aero wheels and even some regular ones. This is a problem when you get a flat in an isolated area. Solution: the Pirelli tires seem to fit easier. Hint: always use the trick to get the bead into the center of the rim.
I just switched (from original equipped Giant Gavia) to these tires a few weeks ago. They mounted without any fuss. Seem much "faster" and definitely more comfortable. Maybe it's in part because I went from 25mm to 28mm. No regrets whatsoever, but now (of course) I'm curious about the Vittorias. Thanks for THAT Mike ;-) . Loved your video and have now subscribed. Cheers from Vaughan!
Nice to hear from a fellow GTA rider. You know about the (poor) quality of our roads, so that extra tire width does nicely dampen up the ride feel a bit.
Thanks for the video. Ended up going with these in 28 over the Vittoria Corsa Pro and Pirelli P Zero (with speedcore). Like you say, the added puncture protection over the Vittoria's is reassuring. The P Zero would have been interesting, but none in stock locally. Been also playing around with the tire pressure calculators from Silca, Enve, and SRAM, surprised to see how much lower the Enve and SRAM calculators are suggesting, some cases 10psi or even more less(!). Your thoughts? BTW nice stealth wheels, where are they from?
I considered the Pirelli P Zeros as well, but didn’t see or read anything that convinced me that they would be a top performing tire. They haven’t been all that well reviewed (although independent reviews are almost impossible to find these days), and their specs aren’t all that impressive. Not terribly light and not a great rolling resistance score (by Bicycle Rolling Resistance). They do appear to have a lot of puncture protection, though. The Vittoria Cross Pro is the one I would have chosen this year had I not gone with the GP5000s. Several people, including @noelpapelera1025 that posted a comment to my video, have said that Vittoria have now solved the issue with their tires being hard to bead, and that the Corsa Pro do mount easily. It’s a 320 TPI cotton-blend casing, so I expect it would have a better ride feel than the GP5000 S TRs. Puncture protection is a bit of a question mark for me. You make an interesting comment on the ENVE and SRAM tire pressure calculators. I didn’t know that. I think there may be something behind this quote I pulled from Silca’s web page explaining how their tire pressure calculator works: “We don't make wheels or tires so we aren't limited by our own products in the recommendations we provide. This is most likely why some other tire pressure calculators out there will have a different rating than we do.” This is just my own personal opinion, and I have no facts to back it up, but this is my thinking. ENVE and Zipp/SRAM are two of the three largest hookless rim manufacturers. With a 73 PSI limit for hookless road rims, they have a big incentive, from a marketing and safety perspective, to ensure riders are not running high air pressures in their road wheels that risks a blow out. For me as an example, I could not run the 80/82 PSI tire pressure that Silca considers to be optimal if I had Zipp hookless road wheels.
They are custom wheels I built myself. Light Bicycle Falcon Pro AR565s rims with DT Swiss 180 hubs. LB is direct-to-consumer and also sell complete wheelsets. I have a couple videos on those wheels.
Corsas are rubbish, the tread peels off the tyre .

Always been a fan of the gp4000&5000, next tire will be either GP s tr or the new pirelli.
You are like 4 years late to the party with this review…
Why does it matter I just bought some myself and like watching reviews on the tires. This video shows how relevant the tires are in the current time.
Very well done review. On the actual tyre width, it is worth mentioning the rim inner width, which determines the actual value. Silca calculator doesn't take into account the different rim widths, which has an impact on tyre pressure. Sram calculator doesn't it.
Yeah, you’re right. Inner rim width does impact tire width. Thanks for pointing that out.

Better get Veloflex

Nice review. I have a set of these tires arriving today being mounted on new DT Swiss PR1400 rims. Can't wait to test them out!
Right on!

How many kms you typically get out of Vittoria Corsas?
…about 4,000 to 5,000 km.
@@bikesbymike it's good enough.
