Team Rabobank is using a tubular Vittoria which is identified with the name "Prototype".
Aesthetically keeps the tread in the famous known Corsa Evo CX, then obviously the news should be in the tread compound and carcass. Probably the news should reside in the number of Tpi (threads per inch) which is made of cotton that the carcass should be about 350Tpi from ongoing 320Tpi. In this way you should have an even lighter tubular and smooth. This development is necessary to increase the competitiveness of the tubes that weight are increasingly threatened by the new tubeless tires.
