Froome snagged the yellow jersey with just one second to spare from Tony Martin. Three stages and three riders in yellow; what will tomorrow hold? Photo: Dan Cavallari | VeloNews

While the bike itself is fairly unassuming, there are plenty of eye-catching bits, including Pinarello’s signature fork with curves and waves aimed at creating a stiff and compliant front end. Photo: Dan Cavallari | VeloNews

Like many riders, Froome uses a Garmin head unit, but unlike so many others, he’s not using the new Edge 520. Photo: Dan Cavallari | VeloNews

The flat back of the seatpost aids in aerodynamic flow and adds another distinguishing touch to the unassuming aesthetic. Photo: Dan Cavallari | VeloNews

Carbon everywhere. The headset spacer dons the Pinarello logo and more carbon weave for subdued beauty. Photo: Dan Cavallari | VeloNews

If there’s an edge to be had, riders and their mechanics will find it. Froome uses what appears to be a custom addition to the Di2 shifting system, allowing him to shift easily from the bar flats. Photo: Dan Cavallari | VeloNews

A 120mm PRO stem gives Froome the reach he needs for his lanky frame. Photo: Dan Cavallari | VeloNews

Perhaps the most eye-catching component on Froome’s bike is the Osymetric chainring that looks like it was squashed like a penny on a railroad track. It supposedly compensates for dead spots in the pedal stroke for more efficient power output. Photo: Dan Cavallari | VeloNews
Pro
Look carefully and you’ll see a raw chunk of carbon glued to the bottom bracket junction. This functions as a chain catcher should Froome come close to dropping a chain during downshifts. Photo: Dan Cavallari | VeloNews

While most riders ran 25mm tires or wider during stage 3, Froome’s tires measure 22mm according to the sidewall. They were mounted to a Dura-Ace rim, and they likely measured closer to 23mm or 24mm. Photo: Dan Cavallari | VeloNews
Pro
While the Osymetric ring supposedly ups the power ante, it can certainly wreak havoc on front shifting. The gap between the derailleur cage and ring teeth is quite substantial when the flatter parts of the chainring pass near. Photo: Dan Cavallari | VeloNews
