I have the new Vittoria Graphene on my C60 and on my Master. On the C60 I run Fulcrum Racing Zero wheels and on the Master I run Ambrosio Excellence wheels. I have not experienced any problems mpunting or dismounting, these tires.
As far as their quality is concerned, I have not experienced any problems. Time and more mileage will tell, however.
These are great wet weather tires.
