- One of the most exciting advancements in tire technology, Vittoria's G+ rubber compound ushers in a new era in tire performance.In partnership with nanotechnology specialists at fellow Italian company Directa Plus, Vittoria developed an exclusive process that incorporates graphene particles into their rubber compounds to make them lighter, faster, and more durable all the while, claims that have been verified in the independent laboratories at Wheel Energy.

Interesting! Thanks Dylan.
Have had a set of the Vittoria corsa graphene + tubulars 25mm. Amazing tires, have ran tubulars off and on for 33yrs. and its definitely the best tub. ever ridden. In the past most of the different Vit. I've used have just worn out so quick these have about 900 miles (club rides and races) on them and you can hardly tell they have lost any tread life. Really good cornering on rough roads!!! So far definitely thumbs up!
Vittoria should use this on plus tires
Another video mentioned that these are prone to sidewall failures when mounted on tubeless ready carbon rims, is it true?
The Revolution G is too grippy in the dry but perfect in wet and ice cold conditions.
When will the tubeless Corsa Speed TLR be available? I can't find anywhere in the USA with them in stock.
+TeslaOsiris Thanks for watching. We have yet to get a definitive ETA from Vittoria. As soon as we do, I'll let you know.
Would have wished to hear more about your own impression during road test rather than just repeat the marketing blabla we all already know/heard. Also about their tubular version which I'm looking forward to.
Marketing blahblahblah aside, I've been stoked on these tires since I've mounted them to rims. Want ride impressions? Get a set and try them. You won't be disappointed.
This might be a very dumb question, but I would apreciate if anyone can clarify that to me. I've read that graphene is very expensive, more than gold even (considering the price of the gram), so if companies were to release bike frames made out of composites that include graphene, they would cost much much more than regular carbon fiber oens. So how come there are such affordable tyres, such as the Rubino pro G+ with graphene in it? I just don't get it.
There are, as in most things, a number of variables. At it's simplest, graphene may be as cheap as a pencil - the "lead" in pencils has a high amount of graphene. On the flip side, creating flawless graphene ribbon in any significant size is pretty pricey. Somewhere between the flawless ribbon graphene (like we would need to build a space elevator), and common natural graphene (like you find in pencil "lead") are a variety of grades. Almost certainly, Vittoria is using FLG (few layer graphene) flakes, which is about $30 bucks per kilo.
And... there's a lot of hype here - pure ribbon graphene does indeed have impressive tensile strength - but that's not what's being used in these tires. It's almost certainly a matrix of graphene flakes in conventional rubber - what that actually does for tires is... well, hopefully sell them. Beyond that, Vittoria hasn't revealed what amount of graphene is used in their recipe, and I'm not aware of any definitive studies of graphene vs non-graphene tires in terms of wear, traction or puncture resistance. If you were expecting a graphene ribbon tire belt, like a kevlar or rayon tire belt, no - that's not what these tires have.
I`ve just fitted Vittoria G+ corsa tyres to my Giant Propel but when not in use they seem to deflate quickly is this common, yeah, I`ve got a pump Terry
Hmmm? Unless you're running tubeless, your tires don't stop air from leaking - that's the job of the tubes. Perhaps there's a bit less "stretch" in the G+ carcass, so any air loss is more pronounced?
The popular Rubino Pro III, now discontinued, had better rolling resistance than the new Rubino Pro G+ that replaces it. However it looks like the higher end Vittoria tires with Graphene will be an improvement over their predecessors. www.bicyclerollingresistance.com/road-bike-reviews
Last time my doctor took a stool sample for tests they found trace amounts of graphene in it.
RIP Pave CGIII.
Nice looking and great grip but too soft and picks up grit and glass splinters that slowly work their way through the tyre
Jesus, all that self-harm.
how to know the Pulley is wore out or not
+Cecily Fu Thanks for watching. If you're talking about the derailleur pulleys, as they wear the teeth become progressively smaller and more pointed. Excessively worn pulleys may be almost entirely devoid of teeth.
Lots of claims repeated here; how about some proof with blind testing?
Graphene isn't new at all, pencils use it! BUT what is new is how they use it in these tires.
+koen miseur well technically pencils don't use it, unless you know of a pencil with with graphite only 1 atomic layer thick.
+koen miseur Thanks for watching. I should have clarified that Graphene, though known for some time, was "rediscovered" in 2004. Pristine, two-dimensional graphene and the techniques required to produce it are a relatively recent phenomenon. To date, Vittoria and their partner DirectaPlus are the only ones employing graphene in tires in order to dynamically change the characteristics of the rubber compounds depending upon the loads.
Yeah like i said, they didn't invent the wheel but they used it very differently. Just made this comment because when u see the video, it's like u said they invented Graphene.
I've read alot about these tires over the last few weeks, to bad they aren't available yet where i get my cycling gear, so i had to order GP4000 II again. I'm Belgian so Western Bikework is a bit far for me to order my cycling gear xD. But great video's, keep them comming!
+Western Bikeworks , How many miles can you still ride after a few punchers/auto-sealant by the gel compound?
