Vittoria Corsa G+ Clincher tyres 2016
Vittoria has recently launched their new Corsa G+ to replace their Corsa CX and SC range. The main change is the use of the new wonder material Graphene which is “1 atom thick”. Quite a statement, but rather miraculous when you consider that Graphene is not only super thin at 1 atom only, the material become super strong, ultra light, transparent and even can conduct electricity and heat. Although in this tyre it won’t be doing the conducting of electricity.
The G+ Isotech compound has graphene particles mixed in which in theory will increase puncture resistance, help dissipate heat and reduce weight too.
The Bicycle Rolling Resistance website has done a scientific test and some comparison analysis with other brands of tyres such as the Continental GP and Schwalbe One. Check out their link to see their analysis here.
eZo Cycle early preview
I have long been looking for a tyre that could compete well as an alternative to the Continental GrandPrix and Schwalbe tyres, most people I know have moved onto the Continental or Schwalbes (mostly due to my recommendations, I might add) Vittoria has been a good brand with good value medium level tyres such as the Rubino, but many of my clients like to put on higher level or pro level tyres. There are many reasons for this trend to premium tyres, most of all is the reduction in rolling resistance and speed gain, but also premium tyres are also very good at puncture resistance these days. Riding in UK city roads does require a good level of puncture resistance due to poor quality roads.
So now Vittoria has replaced their Corsa SC and CX range to become Corsa G+. The Graphene as explained above provides a material that should help with puncture resistance without having to increase weight with a large strip of super strong rubber under the contact compound. Graphene has been a material I have been getting quite excited about and now it’s introduced to the cycle industry in tyres to begin with I just had to try them out. Check out my Strava road test here.
Whilst I was stripping my 28mm Gatorskins off my Genesis CdF, I couldn’t help but to weigh wheels and tyres to gain a comparison, however I knew that the 25mm tyres were always going to be lighter than 28mm tyres, but still I was curious. So not exactly scientific, so bear with me.
Both Vittoria wheels weighed almost exactly the same at 262g and 264g, you can forgive 2g of discrepancy. My Continentals, albeit a few years old now, weighed in at 340g and 349g, can say the rear tyre probably picked up more grit and shrapnel over the years than the front.
My rear wheel with a 9 speed Sora cassette, Alexrim, Shimano hub and 160mm Avid brake rotor disc weighed in 2240g, quite a weigh for a road bike, but then it is a CX bike and needs beefier wheels to take the off road riding that the bike was designed for. So will I lose just 78g from changing the tyres?
Well, as it turns out I had to change the inner tubes too, which had to be thinner width inners, so in total my wheel now weighs in at 2095g, a weigh saving of 145g from the rear wheels. Similar reduction from the front too, so in total I stripped roughly 300g from the bike by changing and upgrading the tyres.
Quite a reduction for some if they were looking for such gains, in my case I wasn’t looking for reductions in weight, but more looking for that as a bonus. I am keen to ride it and find out. Check out my blog on the test ride.
The tyres evidently do feel very light, the rubber compound provides high level of grip, with straight running tread, could cause issues in the wet, but I think they will perform well even in the rain. I wanted the gum-wall look but at the time of purchase they were not ready and so I got the anthracite side walls instead. But on my CdF they look very smart nonetheless.
Being foldable tyres they were very easy to fit on. These tyres would be very good on adventure rides to carry as spares.
Quote from Vittoria themselves:
The clincher version of the world’s best performing tyre pushes the limits of versatility. It’s a fast, flexible, reliable and race proven tyre that’s been used and abused in just about any condition imaginable.
The Corsa has an incredibly low weight, yet thanks to the new Graphene casing it still comes with exceptional puncture protection. It delivers a deliciously floated and super fast ride on the road. It will hold the line in the straight or flying round a corner in the wet, dry or dirty conditions.

- Kevlar reinforced Corespun K for increased sidewall protection”
