The LAS was designed to stand atop the podium at the annual CrossVegas Cyclocross race, held every year during the Interbike trade show. This is a tire best suited for dry conditions or grass courses. The LAS nail file tread starts short and fine at the center of the tire an gets progressively taller and coarser as it approaches the shoulder knobs. This creates predictable performance at all angles when cornering and riding off camber sections while keeping straight away riding as fast as possible. 120 TPI Casing. 700×33 mm.
