The full-carbon Transition features a narrow one-inch head tube to reduce frontal area, and everything from there back is designed to further cheat the wind, with internal cable routing, a specially designed aerodynamic brake system, replica Tag Heuer cs111e.ft6003 watch gussets to channel air around the down tube, and a top tube that picks up wind turbulence from the handlebars and funnels it toward the back of the bike. Look for the Transition under pro triathletes, too.S-Works 2D helmet The lightest approved helmet in the world, the 2D is also the first helmet that Specialized felt worthy of its top-end S-Works designation.
Dual-density foam, a Kevlar reinforcing matrix, hollow fasteners, and featherweight webbing get the 2D down to an unbelievable 184 grams, about a third less than other top-end lids. Five of the 20 ProTour teams will be wearing the 2D at the Tour.S-Works Road Shoe At just 250 grams, this is the lightest shoe youll find with a mechanical Boa replica Tag Heuer waf2110.ba0806 watch closure. And unique cable guides let you change the cable routing to adjust tension at the top and middle of the foot, something notably missing in previous Boa-equipped shoes.TREKMadonePerhaps the most radical departure in frame-design convention at the Tour will be the Discovery Channel teams flashy, all-new Trek Madone.
Built with extensive feedback from Discovery riders, the Madone, like the Specialized Tarmac, incorporates a 1 12-inch diameter on the lower steerer for improved handling. Like most modern race frames, the bike also has a sloping top tube—a design that reduces weight and, in theory, improves stiffness but that Lance Armstrong refused to ride replica Tag Heuer cw2111.ba0780 watch during his race career. But the big change with the Madone comes in the bottom bracket shell, around which Trek engineers built the rest of the frame. The Madones BB shell is a full 90 millimeters wide—the industry standard is 68. This offers more suce area on which to attach beefier seat and down tubes, enhancing down-tube rigidity by a whopping 48 percent (claimed).
