Description Stick like glue.
The Donnelly LAS Tubular Cyclocross tire is a quick rolling race tire designed for aggressive cornering and speed in rough conditions. Taking its name from CrossVegas--the most entertaining and exciting cyclocross race in the US, the LAS delivers blazing speeds on grass and hard-packed dirt.
A unique nail file tread pattern is short and fine at the center of the tire and gets progressively taller and coarser as it approaches the shoulder knobs. The result is a tire that handles predictably in corners and rough conditions while keeping rolling resistance to an absolute minimum. Additional side knobs are lifted straight from the more aggressive Crusade PDX model to ensure complete cornering confidence.
Donnelly Tires were previously known as Clement tires, but due to a licensing have had to change their name. If you have used Clement tires in the past, Donnelly has retained the materials, designs, and compounds in these tires.
