* Named after the most entertaining and exciting cyclocross race in America, CrossVegas, 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, all the while keeping straight-line rolling resistance as low as possible* LAS has the same side-knob construction as its cyclocross brother the Crusade PDX, giving you superior edge control in leans and a traction advantage coming out of the corner* Weight: 350g
