Interbike, the largest bicycle trade show in the U.S., opened Monday with the first of two days of outdoor bicycle testing at Bootleg Canyon, a park about a half hour outside Las Vegas, Nevada.

After the demos in Boulder City, the show will continue with three indoor days at the Sands Expo & Convention Center in Las Vegas.

On the first day outside, VeloNews editor in chief Ben Delaney did some riding and found a few choice bikes to share with readers. Check back soon for more reports from tech editor Matt Pacocha and tech writer Lennard Zinn, who, at last report, were still out riding.
