  • Working in the Dark

    This article will discuss techniques useful to the workers of the bicycle world. Although I try hard not to, sometimes parts are dropped on the floor. Sometimes, very small parts are dropped.

    Andy Hampsten is a former professional racer. Winner of the Giro d'Italia, veteran of the Tour de France, team rider for the Motorola Cycling Team, 7-11, La Vie Claire, and Levi's, Andy has seen many a mile on and off the bike.

  • Calvin's Last Minute Bike Assembly Guide

    Let me begin this article by saying first that if you are reading this hoping to assemble that gift bike, you are already in trouble. Bicycles, even simple "children's" bicycles are vehicles, and are in their own way, sophisticated. You are better off purchasing a bicycle complete from your local independent bicycle retailer. That being said, some parents have purchased a bicycle in a box that needs to go together, and that will be the focus of this article.

    The 2006 Discovery Channel Professional Cycling Team gathered recently for their annual training camp and I was honored and excited to be a part of it.

The rolling hills of California's central coast provide a great place for the riders to establish a base fitness level, as the mechanics and support staff are learning about the new equipment and the needs of the new team members. Since Park Tool is the official tool and maintenance equipment supplier for The Team, I was there to visit the mechanics, learn of their needs for the coming year, and show off this year's new tools.
