Vittoria Open Corsa Evo CX tyre

Vittoria's Open Corsa is a cracking road tyre with a supple feel and good all-round grip. It's not the hardiest through a thorny winter but it's definitely one to consider for your good bike.

Given that the RRP for these beauties is £50 a pop you'd expect them to be packing some tech to justify that price tag, and they are. The carcass of the Open Corsa is as close to that of a tubular as you'll find in a clincher tyre.

When it comes to a supple ride and the ability to deform over a rough surface to give the best possible grip, the most important number is the TPI (threads per inch) of the casing. Tyre casings are generally made from nylon and the thread count is usually between 60 and 150, with some going as high as 220. The Open Corsa uses the same cotton/polymer mix as the Corsa tubular tyre, at 320TPI. That allows for the same strength at lighter weight (215g each for this pair) and means that the casing is more flexible.

Out on the road the Open Corsa does give an excellent ride feel, with 100psi in the tube feeling more like 90 in a standard tyre. They're rated to 145psi and the recommended pressure is 115psi to the maximum, I ran them at my usual 100/110psi and they felt great. The amount of grip they afford from the diamond pattern centre tread and ribbed side sections is very good too. Colour-wise it's the centre tread that changes (black, white, red, blue and yellow are available) with the edge tread remaining black. While that does mean that light colours can get mucky-looking, it also means that the black rubber - which affords the best grip - is underneath you when you're leaning into a corner. Vittoria claim that the Kevlar/Silicon dioxide compound gives reduced rolling resistance and better wet weather grip. I couldn't tell you how much the compound contributed to the rolling of the tyre compared to the high-TPI carcass, but they're fast alright. In the damp the grip is predictable and gives way gradually, so it's always easy to gauge how fast you can take the corners.

The Open Corsa has a latex rubber band under the tread which Vittoria say increases the tyres suppleness and adds puncture protection, and it's somewhere in the middle of the pack when it comes to shrugging off punctures. I've put a couple of thousand kilometres into these tyres over some questionable surfaces and only had a handful of thorns intrude, which isn't bad at all for what's really more of a racing tyre. I also had the pleasure of using Open Corsas at the Di2 launch in Aigle, and they're a super tyre for carving down alpine passes, offering masses of predictable cornering grip and never feeling harsh, despite being fitted to a Giant TCR that's possibly the stiffest road bike I've ever piloted.

With a 'handmade' tubular structure for superior performance and comfort, it has also got a special latex inner tube that increases its elasticity and puncture resistance. Further features are the Kevlar® SiO2 3D Compound with added silica - for reduced rolling resistance and better grip in the wet Our new high density casing - 320 tpi - delivers unbeatable comfort and superior performance with inflation pressure of up to 200psi!

New PRB 2.0 puncture resistant belting placed underneath the tread increases the flat prevention properties of the Corsa Evo CX up to 40%, even while reducing the weight. The new Corsa Evo CX is tougher and faster than ever before.

Kevlar® SiO2 is a compound with a high silica (SiO2) content developed from Vittoria's top range of compounds.

Try them with latex inner tubes - that's how I roll Wink

It's great to see you ran them at sensible pressures. I'm convinced that the vast majority of riders go for far too high a pressure. Harder = faster. Right? Wrong. I'm 75kg and run Vittoria's 320tpi SCs at 90 / 100 with Michelin latex tubes. I'd religiously go to 110 / 120 until a few months ago. Having had the confidence to drop it down I've been rewarded by a far less fatiguing ride, and there's no way I'm running slower than before.

Actually, on rough surfaces, the lower pressure can be faster - it gives the bike the ability to glide more over the rough patches, instead of forcing to bounce up and over the bumps. It also means that there's less skipping and skittering, which means more grip when cornering but also more time with your back wheel in contact with the ground (and so more power being applied more evenly). Better all round if you don't ride on good roads!

No one has mentioned the wonderful 'swooshing' noise they make!
Mounted on full carbon rims and on a satin smooth French road surface.... Phwawww!
I go with Conti supersonic tubes and wouldn't use any other tyres.

I used these tyres all last summer. They are fast and have a great feel, but wear is terrible. After about 700 miles the 'file' tread on the rear had gone smooth and the 'flat spot' developed. I have found Vittoria tyres often wear quite fast as compared to Schwalbes or Contis. At the moment I'm trying Michelin Pro4 Endurance, which have done about 1000 miles so far with no sign of wear. There's no tread pattern to wear down though, so it might be harder to tell how worn they are.

This tyre should not be compared to any other in all aspects - it really is in a different league.

The ride quality is absolutely transformational but IME unfortunately the rear tire got slashed on the tread after 100kms so that the tire was a write off. Front seems okay but they are a bit sketchy in the wet, I think.

Overall though, they are worth it if you have some clean roads as even the best of the rest - ZX, GP4000S etc just do not compare in terms of ride quality and I like both ZX and GP4000S!
