Bridgestones, on the other hand, have an incredibly stiff carcass

less suited to the Bridgestones.
also underlines exactly how important tires have become since the
introduction of the single tire rule. By limiting the design and
construction of the available tires to just two compounds (soon to be
three compounds, but still), the room to modify the behavior of the
bikes using the tires has completely disappeared.
