Newest G 2.0 version A super fast tubular tire engineered for pure speed events and profiled to benefit from the latest wide-aero rims. By using Graphene, Vittoria have created a tire that has incredible grip but low rolling resistance. Graphene is a revolutionary material in the form of a very thin, nearly transparent sheet of pure carbon. In its extreme form it is as thin as a single atom (1/1,000,000,000th of a meter). Vittoria uses Directa Plus Graphene called G2.0, which is 2 to 8 atoms thin. 700 x 25 all black The return of glued tubular tires with patent defects will not be accepted, it is the responsibility of the purchaser to determine if any patent defect is present in the tire or tires. Tires should be dry mounted on a clean rim and thoroughly checked before gluing. This type of inspection should routinely be done on any tubular tire during the stretching process |
