Clement Cycling LAS Tubular Tire, Size: 700cm x 33mm Named after the most entertaining cyclotrons race in America, Cross Vegas, the LAS is fast and glides over hard pack, and cuts through grass Its unique nail-file tread is short and fine at the center of the tread and gets progressively taller and coarser as it approaches the shoulder knobs This gradated construction gives you predictable performance as you corner and ride off-camber sections Las has the same side-knob construction as its cyclotrons brother the crusade pox Gives you superior edge control in leans and a traction advantage coming out of the corner
