Cervelo

S5 Dura-Ace Di2 Road Bike

What Our Gearhead® Experts Are Saying:

"If you want a bike that’s proven at the sharp end of the pro peloton, the S5 Dura-Ace Di2 is it. The aero shaping, Reserve 57|64 wheels, and Dura-Ace Di2 group make this one of the fastest, most stable road bikes I’ve ever ridden. It’s seriously quick, but still feels planted and confident, even in crosswinds."

We’re always chasing the next level of speed, and Cervélo’s S5 Dura-Ace Di2 is the benchmark we measure everything against. Right from the first pedal stroke, we feel the legacy of the S5—its iconic V-stem and bayonet fork have dominated the world’s fastest races, and now, with this latest evolution, it’s even more formidable. Cervélo’s relentless pursuit of aerodynamic gains means the new S5 is over 6 Watts faster and 124 grams lighter than before, with a redesigned front end and a one-piece handlebar/stem that slices through the wind. We love how the Reserve 57|64 Turbulent Aero wheels, co-developed with Reserve, perfectly match the S5’s asymmetric seat tube, delivering stability and smooth airflow even in gusty conditions. Every detail, from the Dura-Ace Di2 wireless shifting to the carbon cockpit and dual-sided power meter, is engineered for pure performance. When we line up on the S5, we know we’re riding the fastest, most refined aero road bike out there.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
