A durable carbon black compound, good puncture protection and the Duraskin fabric make the Gatorskin a veritable kilometre eater. Available in widths from 23mm to 28mm, it can be used on the way to the office just as well as for serious training or when touring with baggage. The Ultra Gator Skin is a virtually indestructible training, touring or commuting tire featuring a combination of three flat protection technologies. Super fine 170 tpi casing plus a bead-to-bead layer of Dura Skin, and a Kevlar(r)-reinforced layer directly under the tread. Black tread with brown Dura Skin side wall. An immensely popular tire, durable, rugged and at a good price.
