Cervélo S5 Ultegra Di2

The S5 doesn't just win races—it dominates them. Yellow jerseys, pink jerseys, green jerseys—you name it, this bike has claimed it. For years, the Cervélo S5 has ruled the front of the peloton, carrying legends like Wout van Aert, Marianne Vos, Jonas Vingegaard, and Simon Yates to victory on cycling's most prestigious stages. And just when you thought it couldn't get any better, Cervélo has made it lighter and faster than ever before.

The latest S5 sheds 124 grams from the previous generation through optimized carbon layup and upgraded hardware, all while adding depth to the fork and head tube. Those deeper tubes aren't just for show—they slice through the wind, saving you 6.4 watts compared to the previous S5 and keeping you at least 5 watts ahead of the competition. That's the kind of free speed that wins races.

Every S5 comes equipped with Cervélo's innovative Plus-Four concept handlebars, featuring a 4 cm flare from the hoods to the drops. This design puts you in a more efficient, aerodynamic position when riding on the hoods, while still delivering rock-solid stability in the drops when you're sprinting for the line or carving through descents.

To match the S5's performance, Cervélo partnered with Reserve to create the 57/64 wheelset. True to the redesigned S5's philosophy, these wheels are lighter than the previous generation's 53|62 while shaving off another 3 watts. It's the complete aero package.

Want to make sure everything fits perfectly? Cervélo offers a 60-day handlebar swap on the original HB19 that comes with your S5, giving you plenty of time to get a professional fit and dial in your setup exactly how you want it.
