|If you want to get the miles in, the Sprinter GatorSkin has you covered. The Sprinter is the ideal tire for shorter, ultra-fast events like criteriums. Although it is light enough for serious racing, it is also strong and durable enough for training. With the long-wearing carbon black tread compound, a Kevlar nylon anti-puncture layer, and the added protection of the DuraSkin sidewall, this is one true road warrior. Casing construction is 3 layers of 60 tpi fabric for a claimed 180 tpi.
