Peter Nwrote a review of Vittoria Corsa G Plus Tire - Clincher on February 1, 2016
Familiarity: I've put it through the wringer
I've been riding these tires for the last 4 months after spending most of my time the last 2 years on Open Corsas and can say that they took everything that was great about that tire (supple road feel, excellent cornering grip) and upped it big time in the durability department (perpetually the biggest complaint about previous gen Open Corsas). I won't claim to fully understand Graphene but it seems to have really worked in making the tire a lot more tough and wear resistant without taking any qualities away. Based on wear pattern so far i don't think i'll get as much mileage as GP4000 SII but am far happier with its performance and would gladly trade some of the durability any day.
