Built around a frame used by some of the world's greatest riders, the Cervelo S5 Ultegra Road Bike delivers superb mechanical shifting with top aerodynamics. Boasting Cervelo's All-Carbon construction, the S5 frameset has been developed and refined extensively in pursuit of aerodynamic perfection. With airfoil tubing and a cutaway seat tube reducing the turbulent airflow produced as this bike moves through the air, your next ride can be more efficient and faster.
Futureproof cable management routes the wiring from the Ultegra R8000 groupset in a neat and aerodynamic manner, while ensuring that the cockpit is as clean and clear as possible. With Shimano's reliable and seamless Ultegra R8000 mechanical groupset delivering responsive and accurate gear shifts. An 11-28 tooth cassette pairs with a 52/36t chainset to equip you with the right ratios to tackle tough climbs as well as long flats.
The aerodynamic design continues with the Cervelo S5 seatpost and Aero AB04 handlebars, bringing full wind cheating benefits across the finishing kit of the bike. A top quality Fizik Antares R7 saddle provides the perfect perch for commanding this fast and responsive road bike.
Using Mavic Cosmic Elite clincher wheels for a robust and smooth ride quality and Yksion Elite 25mm tyres for outstanding grip, this is a pedigree racing machine that's designed to deliver.
Please note: The seatpost may require cutting down to size, depending on your fit. Sigma Sports recommends this is carried out by a certified bike mechanic.
