Viva LAS Velocity
The Donnelly LAS Tubeless Cyclocross Tire is your choice for a low-profile, high speed CX tire. The diamond-file tread at the tire center offers extremely low rolling resistance for flat-out efforts. However, the tread grows larger as it moves outside to the race-proven PDX side knobs for incredible grip in corners.
LAS is the airport code for Las Vegas, Nevada, the original home of the world-famous Cross Vegas cyclocross race. This mostly grass course required the fastest tire a racer could use and the LAS delivered. Far from the Mojave Desert sands though, this is also the go-to for snowy, rutted, icy cyclocross courses conditions when you need as much surface contact as possible to keep your tires planted.
