Product Information

Cervélo S3 Ultegra 8000 Aero Road Bike 2018

The S3 is "quite possibly the perfect bike" according to Ride Magazine, and we would have to agree. 'Thoroughbred meets workhorse' is Cervélo's characterisation - it's a bike for those who want speed without sacrificing all-day comfort; who want to ride all year round in all conditions and on all sorts of roads; and for whom the local criterium or club run is as fun as a sportive or an Alpine climbing adventure. With the Cervélo S3 it's no longer necessary to sacrifice speed for comfort, weight for aerodynamics, or vice versa, because the S3 is the complete package.

Full Specification


A completely redesigned chassis for the 2018 S3 combines new, more robust airfoil sections with a rear triangle borrowed from the revolutionary Rca road frame. The dropped downtube enhances frame stiffness while the flattened trailing edge makes bottles an integral part of the bike’s airfoil design. Overall improvements focus on all the perks you want in a workhorse of a bike: Future-Proof cables allow for easy set up of internal electronic, mechanical, or hydraulic shifting and braking lines. Increased clearance allows you to choose up to 700x25mm tires. The Cervélo S3 aero road bike teams category-leading stiffness and ride quality with an award-winning aero frame that is hard to beat for riders who want to do it all, without sacrificing anything.


Incorporating the proven aero features that have made the S Series the pinnacle of aero road bicycle development, the S3 will make it feel like you’re cheating more than just the wind. From the Dropped Downtube to Shielding Seatstays, all frame shapes are designed to smooth airflow over the entire bike and rider as a system. Our Partial Seat-tube Cutout improves airflow around the rear wheel, while allowing for 700x25c tire clearance. 


Cervélo are more than happy to destroy the myth that aero bikes can’t be forgiving – even after a long day on dodgy roads. Borrowing from the Rca’s rear triangle design, thinner seat stays offer class-leading comfort and compliance, while the 25 mm tyres give the possibility of even greater comfort.

This asymmetrical 79mm bottom-bracket standard yields stiffer and lighter frames and crank systems.

Carbon dropouts
Tough, compression-molded dropouts save weight with no sacrifice in strength compared to traditional metal dropouts.

Evolved steerer design
The fork steerer’s diameter has a noticeable effect on a bike’s handling. Evolved steerer design applies the diameters and taper designs that best suit each model.

Future-proof cable management
Ensures your frame is compatible with all current and future derailleur and brake systems.

Partial seat tube cutout
A close-fitting curve in the seat-tube’s trailing edge improves aerodynamics by partially shielding the leading edge and top of the rear wheel.

Reduced-friction BB guide
Significantly reduces cable friction in the bottom bracket, which means smoother shifting, easier setup and longer service intervals.
