Bikes At Le Tour de France

Four Italian bikes (one of which - Kemo -  is actually designed in Switzerland but assembled in Italy) are featured among the 22 teams at the Tour de France: Colnago, Bianchi, and Pinarello. There are two teams based in Italy (Cannondale and Lampre-Merida) who are not using Italian bikes.

Holland's Lars Boom rode a Bianchi to a stage win (which featured cobblestone) at the TDF.

The U.S. is the only other country to have four bicycles in the tour with Scott, Cannondale, Trek, and Specialized (who are associated with three teams). A couple of Swiss (Team Machine and Kemo mentioned earlier), German (Focus and Canyon) and French bikes (Look, FDj.fr) are participating as well. Other bikes include Fuji from Japan, and Belgium's Ridley is sponsoring its compatriots in the Lotto-Bellisol team.

Canadian bike manufacturer Cervelo are associated with Garmin-Sharp.
