From the training rides that boost endurance to the races that pit you against the pack, the Vittoria Rubino Pro G2. 0 Tubular Tire is designed to handle every obstacle you need to overcome on the road. Vittoria's Rubino line is well-known for its longevity and versatility, and the Pro G2. 0 tows the line with 290 threads-per-inch to handle the pressures of competition--and the pressures within the tubular setup. If conditions worsen on the road, a technical tread pattern delivers advanced stability to keep you upright, even if the road turns unexpectedly into gravel.
