The LAS clincher was named after the most entertaining and exciting cyclocross race in America, CrossVegas. The Las tire rolls fast, glides over hard- packed terrain, and cuts through grass. Its unique nail- file tread is short and fine at the center of the tire and gets progressively taller and coarser as it approaches the shoulder knobs. This version of the Las tire is tubular. The casing is airtight and creates a very light- weight tire.
