Dave Wiens, Lance Armstrong and Manuel Prado recently finished first, second and third respectively at the Leadville 100 last weekend while riding the 7000 Series Race wheels.
Dave and Lance have other sponsor obligations but given the green light to run what they wanted to use to win, they both opted for the Race wheels with Crow tires. The end result was Dave winning by a two minute margin and setting a new course record in the process. Manny has spent all season on the Race wheels and continues to impress.
A good video is available at Superhumanmag.com. Also, check Jeff Kerkove's blog for the perspective of a pro rider in the race as well as a teammate of Wiens.
