Is the tubular more used by prof., completely revised for 2009, confirms his position as the best tube for performance, sliding, low weight and comfort

The Company

Vittoria has for over 50 years (it was founded in 1953) which is inserted in the market for tyres bicycle, becoming over the years a landmark in the field.

The constant search to improve the product and the proximity to the most famous names in international cycling, allowed it to achieve a degree of notoriety, but mostly technology and quality, that very few other competitors can boast. Today, Vittoria is a major industrial group in the whole world and the main supplier of professional teams and national teams. Among its flagships are the carcasses with 320 threads per inch, the wide range of products covering all market needs, and finally the many victories in the most prestigious competitions of the year are in addition to his palmares.

The Victoria’s range

Vittoria is a company committed to 360 ° in the world of cycling, and this helps give it a complete range of tubular and tyres going to cover all areas of cycling: road, cyclocross, mountain bike, hybrid, tourism, city-bike, together with inner tubes and repair kits. At the top of the range are the pipe and tyres with 320 threads per inch, the lower ones with 26 threads per inch. In between there are 290 threads, 220 threads, 120 and 60 threads per inch. The high number of wires can have a body more flexible and lighter, more comfortable and smooth. This is because you can use smaller wires and light, which can form a more compact texture which should be less rubber to be covered. It comes, therefore, to a tyre (or tubular) lightweight, yet comfortable and durable, as well as sliding. The range of tubular sees its top model Corsa Evo CX 320 threads per inch and carcass in cotton, we have the tubes with 290 threads per inch, with 220 and 120 threads per inch.

The Vittoria Corsa Evo CX on test

Victoria has worked hard to renew its tubular tip so we can say that little has remained the same except the name. In developing the new product was started by the demands of professionals who use products Vittoria in the race, their claims has resulted in a completely new product, even though apparently the same as the old model. This is because the tread pattern was kept the same, because the particular pattern used from Victoria was considered excellent by all the professionals and so it is preferred not to change a winning design, keeping the classical structure, which was also his old Corsa Evo CX. The new firm, however, are located inside the tube, also made by hand and house in latex, more lightweight, flexible rubber classical, ache if its adoption brings to frequently check the pressure of inflation because the non-butyl is impermeable to air 100%. In search of greater comfort and with greater fluency has further developed the carcass of cotton that now has come to have 320 threads per inch, a record that only holds Vittoria. This was achieved through the implementation of a cotton thread up and even more devoid of Kevlar, it is possible, just to get a lighter casing, however, more flexible and resilient. The lightness of the body affects the weight of the tube, which in fact decreased, the resistance affects the duration, the ability to be inflated at high pressures (up to 14 bar) and the resistance to drilling, and flexibility affect the smoothness and comfort. A flexible body absorbs and distributes over the entire surface of the rim shots of the land, unless the transmitting frame and the rider, so also, the wheel does not bounce on disconnections remained well adherent to the ground, improving the transmission of power, speed and fluency. The compound in which the tread is made is high in silica by the addition of microscopic fibers of Kevlar. This particular union to obtain a compound with a very high even on wet roads, low rolling resistance and good durability. Although this varies according to the weight of the rider, the frame used, the position in the saddle, weather conditions, routes addressed, was valued at about 4-5000 km, a value more than excellent for the type of tube. The tread compound is double, the hardest in the center, to improve the duration, and softer on the sides to improve grip on corners, a technology already well established in Victoria house. Another innovation introduced in this tube, and other products of the range in 2009, is the new anti puncture PRB 2.0. Even in this case we have heard the demands of professionals who demanded greater protection against punctures. The puncture Resistant Belting 2.0 is based on a new aramid fiber developed by following a process of manufacturing new, thanks to which the individual filaments are interwoven various times and in different directions, forming a plot so dense and structured as to be virtually impenetrable. This was achieved using the new wire, fine and valuable, which enabled the construction of the new weave that increases the resistance to puncture by 40% compared to the previous model while being lighter. The new Corsa Evo CX is available in colours black, or until all blacks and central line of red, yellow, blue or white, as far 700x21. 700x23 The measure is only available all black and measure 26 inches across is only available in black and measure 26x20. For all of the inflation pressure is 8-14 bar. The weight ranges from 205 grams of the 26x20 version, and 250 grams of the 28x23 version, while the 700x21 has a stated weight of 245 grams. We, as we noted 700x23 weighs 245 grams.

The road test

We tried Vittoria Tubular Corsa Evo CX for over 1.000 km, in conditions not very favorable weather, with cold and often wet asphalt even rain. This has particularly affected the consumption pattern which in fact was practically nil. The tubular mounting problems and does not create an expert performs the average operation in a short time. Of course it should be left dry for the putty well, but after 24 hours the wheels are ready. The room in butyl forces to control the pressure at each exit, you can always work around this problem using the Pit Stop for Victory, which also eliminates the possibility of breaking, the latter for three months. A question of habit, however, as soon you get used to check the pressure before you leave, and it becomes natural. Respect, however, the use of the Pit Stop for fear of boring our recommendation is to wait to drill, because especially now with the new protection is very difficult to puncture the tube, which, however, even with the "old CX" there was the same, which demonstrates that the possibility of drilling a tube is very remote and is not the case to give up his purchase as a justification for the fear of breaking. Since the first cycling rediscover the behaviour that had impressed us last year trying the Corsa Evo CX and was further improved on this new version. First we show the high fluidity of the product that succeeds in rolling resistance in asphalt with a truly minimal. Compared to the old model, we feel that this is actually been improved, although it appears more the comfort factor, where you can actually appreciate further work done on the evolution of the carcass than the old model. Comfort and fluency in particular are asking for absolute top of the class and the low weight does nothing but accentuate the performance especially in the variations of speed, where the new tube can be faster than the old (minimum difference anyway), but in general the performance Global new Corsa Evo CX to be higher. Disconnected on the stability and traction are especially good, with the tube that bounces very well while remaining adherent to the ground, then a Garand optimum power transmission and general driving safety and control. The round profile of the tread also makes inputs fast, but precise and gradual, with a good control of the vehicle when cornering, even at inclinations greater. The same good behaviour it has in braking when the center of the tread ensures a stable base of support and safe. These factors would high benefit in guided tours and fast, as in very long runs. The sensation of control is always high, as is the communicativeness of this product, so you can "dare" most of the others, to be faster, but ultimately a lot less risk of others, an advantage not just. The pattern has repeated confirmed its qualities, so good on dry runs, but it is effective even with moist or wet asphalt, and only at high pressures and very wet asphalt goes into crisis, but it is natural. In these cases you should get off at the minimum pressure of inflation, to find the correct tension and security, while in the remaining cases can be easily possible to obtain an absolute glide to the top combined with an excellent comfort.

Corsa Evo CX 290 tpi Vs Corsa Evo CX 320 tpi

Between the old and the new Corsa the deepest differences are not, as is natural in the evolution of a product that is already placed at the top of the world market, but nevertheless there are. In general we can say that the new Corsa Evo CX is even more smooth and comfortable with the former model, minor differences, but still felt (obviously on a level playing field techniques), with greater speed in reaching high speeds and greater ease in maten, improved traction on uneven and a better ability to absorb disconnections to the maximum pressure allowed. The grip, however, and behaviour in curves or during braking are the same.

Corsa Evo CX 320 tpi Vs Open Corsa Evo CX 320 tpi

The two top range of Vittoria, virtually identical in construction, are both top of their respective sector. This is despite the tubolar, despite the view of many fans, it remains higher than the overall tyre. First is much more comfortable, because the same construction is able to distribute the blows over an area greater than the tyre, this also translates into better traction and greater driving safety and control (of course we are not talking deepest differences, but it felt). Less clear, however, the difference in smoothness, though always in the top tube. Where the tube, however, he returned to win again so decided is in the behaviour in the curve, where the roundness of her Try it allows you to draw trajectories safe and accurate with a better support when cornering compared to tyre that has a more pointed Try creating a behaviour more nervous and less precise cornering. That is a drop in the tube is guided clearly benefited and can give an added benefit is lacking to tyre. Safety in braking, cornering downhill, center curve, stability and directionality of the outgoing curve, are much better compared the tubular to tyre. It is precisely these aspects so that professionals can choose the tube instead of tyres. In general, therefore, we can say that for comfort and overall performance, the tube continues to be clearly win on tyre. New technologies anti drilling, then, have further reduced the disadvantages of the tube compared to tyre and today can be summed up in just need to paste the same to the circle and wait at least overnight before using it, which is not with tyre. Considering, however, differences in performance, we believe that the budget will remain broadly supportive of the tube. This without taking anything away from the Open Corsa Evo CX that remains the best tyre on marketing.

Conclusions

The tubular Vittoria Corsa Evo CX confirmed to be the best product on the market. The evolution has not been made to the facade but the substance and the new Corsa Evo CX is more flowing, comfortable and faster than the old one. Its strengths are the ability to stay in contact with the ground Better transmission of power, safety and driving speed. The profile of the tread, very smooth, leading to a progressive and honest behaviour in the curve, where the sensation of security and control is never less. It confirms the top smoothness. In conclusion the overall performance we expressed this tube the best on the market today.

The price

The price of just over 60 Euro one is amply justified by the benefits arising from the construction and manual tube.

Is suitable for

Athlete: it is the primary choice of all professionals, except when they are bound by obligations of sponsorship.
GF cycling tourist: the comfort and safety are driving factors to be not under taken, good length (just below tyres from a workout, but with much poorer performance), excellent anti puncture protection, a choice that goes against, but who test hardly come back.
