Tech Talk: Uphill time trial bikes
Here's a look at the bikes prepped in Grenoble for Stage 11. Lance Armstrong's uphill time trial bar was cobbled together by Louisiana aerodynamics guru John Cobb. They featured Profile Carbon-X extensions and hardware of his own making to position the pads out of the way of the hands, and the extensions at the right wrist angle. Note the non-STI left brake lever (he uses a down tube shifter for the front derailleur to save weight on his climbing bike). In the uphill time trial, Armstrong also used Munich-made Lightweight composite wheels, which have carbon-Kevlar spokes and carbon hub
