The driveside of the Neo Pro TT is equally striking with smooth contours and neatly integrated chainrings. (Image credit: James Huang/Cyclingnews.com)
The driveside bottom bracket cup is also shrouded by the crankarm. (Image credit: James Huang/Cyclingnews.com)
Ceramic bearing-equipped pulleys help keep things rolling with minimal friction. (Image credit: James Huang/Cyclingnews.com)
Like many riders in the peloton, Cancellara uses a slightly chopped saddle to squeak by the UCI setback requirement. (Image credit: James Huang/Cyclingnews.com)
Cancellara is the current time trial world champion and can now add 'two-time Tour de France prologue winner' to his list of palmares. (Image credit: James Huang/Cyclingnews.com)

Time trial bikes are visually striking but not always the easiest for the mechanics to work on. (Image credit: James Huang/Cyclingnews.com)
Saddle height adjustments on the first-generation BMC TT01 Time Machine was accomplished via a nightmarish array of small set screws. (Image credit: James Huang/Cyclingnews.com)
A unique jig helps Astana mechanics achieve a perfect setup. (Image credit: James Huang/Cyclingnews.com)
T-Mobile was spotted running a new HED three-spoke wheel with a substantially deeper, and non-structural, section than the original version. Hidden beneath the fairing is likely a shallower section rim that is bound to offer a more compliant ride. (Image credit: James Huang/Cyclingnews.com)
Not all of the T-Mobile riders were using the new wheel, however; many were utilizing the four-spoke PRO front wheel as supplied by team sponsor Shimano. (Image credit: James Huang/Cyclingnews.com)
T-Mobile mechanics hand-applied a line of silicone adhesive to fill the wind-churning trough in between the tire and rim. (Image credit: James Huang/Cyclingnews.com)

Integrated time trial handlebars leave little room for mounting accessories so Caisse d'Epargne mechanics have to use a bit of creativity in mounting Valverde's heart rate monitor. (Image credit: James Huang/Cyclingnews.com)

Race Tech: Tour de France, July 8, 2007
Riders will use their dedicated time trial bicycles for what will barely amount to the blink of an eye in the grand scheme of the three week-long Tour de France. Nevertheless, sponsors, teams, and mechanics spend an inordinate amount of time, energy, and money into developing the fastest bikes to propel them across the line.
While typically not the lightest bike in the quiver, time trial machines are easily the most visually striking of all the machines we'll see as the peloton winds its way into Paris with CFD-carved lines, NACA-designed tube shapes, and every aero-enhancing tweak and friction-reducing trick that teams can slip through the eyes of the UCI.
This year's opener was won in convincing fashion by Team CSC's Fabian Cancellara, an undeniable favourite but not the home-grown Brit as the host city had hoped; Bradley Wiggins (Cofidis) was the highest UK finisher at fourth, 23 seconds back.
