Put simply, I was shocked to see that it rolls faster than the lighter weight Turbo Pro. The Roubaix Pro is officially the sleeper in the Specialized tire line. Looking for a tough tire choice for a questionable race course? This is your tire. The price is right, the quality is there, and the Crr is outstanding for a tire that is this durable.
