A 120 TPI casing gives the Maxxis Hors Categorie the supple, high-performance ride that you would expect in a professional-level road racing tire. It offers two different rubber hardnesses to optimize your ride. The harder 62a center has ultra-low rolling resistance and wears slowly, while the softer 57a side offers incredible grip in tight corners. The casing is nylon with a 2-ply breaker for strength and durability.
As with all Maxxis road tires, the Hors Categorie really shines in the value column. You get a lot of good technology and product for the price.
