With a lightweight, tubeless-ready, open tubular casing, the Vittoria Corsa Speed G Plus Tubeless Tire is billed as the world's fastest tubeless tire and features revolutionary graphene technology for an unprecedented mix of low rolling resistance, durability, and all-weather grip. The Corsa Speed G Plus is the culmination of a collaboration between Vittoria and an external company, Directa Plus, to adapt a carbon compound known as grapheme for use in bike tires. The resulting compound is dubbed G plus, and Vittoria claims that its inclusion significantly reduces rolling resistance while increasing the durability Vittoria has long been known for.
The inclusion of graphene is credited with enhancing traction, increasing durability, and reducing rolling resistance, and its impressive strength-to-weight ratio keeps the tire well-suited for racing by reducing rotational mass. According to Vittoria, the combination of G Plus and Isogrip compounds creates a tire surfacing that also rolls fast in both dry and wet conditions for confident cornering and handling no matter what nature comes up with when you're battling it out on rolling country roads.
Vittoria claims that the elasticity and carbon construction of graphene creates an incredibly durable tire, but for even more reassurance it utilizes a corespun casing to increase the tire's lifespan. With multiple cotton fibers twisted together to create one yarn, core spun casings are significantly more supple than typical casings without adding unnecessary weight to the tire.

Great performance, not durable
- Familiarity: I've used it several times
Rolls fast and smooth with great handling. Very thin casing and punctures easily. 80 mile róad ride today and front and rear suffered many punctures and 2 gashes requiring a tube in the front to get home. Prior tire Corsa CX 3 with STD or latex tube. Went through 3 of these tires (speed g) in less than 2 months (tubless) where as I get 2500-3000miles out of the Corsa CX 3 rotating front to rear with new going to front. Never got a chance to get mileage figure on these. Race Day ONLY in the future with Stan's pro sealer.
The Fastest Tire

I have around 400+ miles so far on these tires. I am running them tubeless with sealant. The vast majority of my biking years I have ridden tubular. Almost always Vittoria Corsa Evo in rear and Crono Evo in front. About 6 months ago I decided to try tubeless so I purchased some cheap 38mm Chinese Tubeless rims (don't be hating, lol) and put Schwalbe Pro One Tubeless tires on them. I liked them but certainly didn't feel that they were an improvement over my tubular tires. Then I read about the new Vittoria Speed G+ and ordered a pair. OH MY!! Boom, within the first few miles of my first ride I knew these were the fastest, smoothest tires I had ever ridden. Yes, better than tubular!! I know some have reported flat issues but I have yet to get a flat in over 400 miles and they truly do not look that worn. I have heard that the first version that had the "gum" colored sidewall were more puncture prone and that Vittoria made some changes and went with the gray/anthracite sidewall which is more puncture resistant. I have the gray/anthracite so perhaps that is why my good luck. This change also increased the weight slightly so they are now rated at 220 g. as opposed to 205 g. Mine weighed right at the claimed 220 g. I ride on mostly good roads and am very careful/attentive to avoid "junk" on the road. I weigh 155 lbs and have found through experimenting that 95 psi front and 100/105 psi rear works best for me. VERY happy with these tires.
Interested in running these tubeless on my Enve 7.8s for a race. Will the tire work with those rims?
Verdict still out on these...

I was very excited to try these as my first tubeless experience. Got them on without any trouble. They are marketed as the lightest and fastest tubeless tires, which I don't disagree with. They are/were very fast and handled amazingly well. Over 3 weeks I put around 450 miles on them and got 3 punctures 1 on front tire and 2 on the rear, initially the sealent worked to stop leaks but then over the next week I kept getting leaks in the same spots, eventually leaving me with no choice but to put in a tube. The tires looked pretty banged up for having 450 miles. Finally on my last ride a child ran into the road and I ended up skidding for about 5-8' to avoid the kid and that was it for the tire. I burned straight through it. I don't make a habit of skidding around but was pretty surprised at the result none the less. Took it to my LBS and got it warrantied and will give it another chance.
Flukey stuff can happen even with new equipment so not sure if it's bad luck or if it's due to soft, paper thin tires.
To be continued...
Update. The new tire pretty much lasted about the same as the first two. I don't use those tires anymore they were far to delicate. Definitely a race day tire. Day being the keyword because in my experience that was about all I got out of them.
