Peter Sagan is one of the most colorful world champions in recent memory, entertaining — and occasionally surprising — fans both on and off the bike. In celebration of his year-long reign as arguably the top road racer in the sport, Tinkoff-Saxo bike sponsor Specialized has provided Sagan with a similarly colorful S-Works Tarmac. U.S. tech editor James Huang took a closer look at the bike used to win the first stage of this year’s Amgen Tour of California.

Paying homage

Just as you’d expect, Sagan’s custom painted bike proudly wears the UCI world championship colors of blue, red, black, yellow, and green. But instead of the usual striped motifs that have graced the bikes of countless previous champions, designer Ron Jones has arranged that rainbow in a bolder camouflage pattern that wraps its way around the top tube, head tube, down tube, and seat tube. Cleverly, all of that color is also oriented in such a way that it’s visible from all angles but never overwhelming in any particular vantage point.

More traditional UCI rainbow stripes adorn the Roval carbon tubular wheels, the FSA K-Force carbon seatpost, and even the SRM PC8 computer head, and the names of past world champions are subtly integrated into the ’S-Works’ logo on the down tube. Up front is a gold-plated head tube badge.

Sagan isn’t just the current world champion, however — he’s now a brand in his own right, and his bike reflects a host of more personal touches.

In addition to the UCI rainbow, Jones has also integrated the colors and icons of the Slovakian national flag, including the double cross and triple peaks borrowed from the country’s coat of arms.

Meanwhile, Sagan’s personal logo — which is officially trademarked — can be found on the top tube, custom Prologo Scratch 2 Nack saddle, and even the underside of the Look KéO Blade Titanium pedals.

Sagan has not only avoided the dreaded 'rainbow curse' so far this season but seems to actually enjoying his status as the current world champion.

Mechanically, Sagan’s bike is mostly straightforward with a Shimano Dura-Ace Di2 electronic transmission, an SRM/Shimano power meter crankset, Roval carbon tubular wheels wrapped with Specialized tires, an FSA traditional-bend alloy bar and carbon seatpost, Tacx Deva bottle cages, an SRM-specific K-Edge chain catcher, and Supacaz bar tape.

CeramicSpeed hybrid ceramic bearings are fitted to every rotating component, too — including the company’s own thread-together bottom bracket to combat creaking inside the press-fit shell.

Total bike weight is 7.46kg (16.45lb).
