All-purpose open tubular design that will give you more than you can expect from a clincher tire. Built with the same 320 TPI casing of our tubular tires for low rolling resistance and incredibly supple ride feelings. Suited for training and racing for everyone that wants the excellent characteristics of a tubular and ease of mounting of a clincher. The special tread provides outstanding grip and cornering stability in all weather conditions. The Master comes with gum colored sidewalls for a vintage look.
