Cervelo S5 Ultegra Road Bike 2017
Now even faster and stiffer, the Cervelo S5 Ultegra Road Bike 2017 is the ultimate aerodynamic, high-performance road bike. Using many of design cues and aerodynamic features found on Cervelo’s P-series time trial frames, the Cervelo S5 Ultegra Road Bike 2017 is stiff, lightweight and incredibly fast.
Adorned with Shimano Ultegra 6800, 11-speed components, with a Rotor 3DF BBright™ chainset, Mavic Cosmic Elite S wheels and a Fizik Antares saddle. There are many new changes for 2017 including a stunning black and white colour scheme, sure to make you stand out from the competition.
Phenomenally fast and stiff, with a wider, more aerodynamic headtube and fork, housing a tapered steerer and now offering 25-millimetre tyre clearance. You can now get lower than ever before, with a lower stack height than its predecessor. With a 35% increase in stiffness in the head tube, this is a real race ready bike.
The dropped downtube design is incredibly aerodynamic and wraps, seamlessly, round the front wheel. Staying hydrated has never been faster than with the Cervelo S5 Frameset 2017, incorporating carefully placed bottle cage bosses, allowing perfect efficiency in the wind, whether using bottles or not.
Future-Proof Cable Management is a nice touch, resulting in the frameset being compatible with electronic and mechanical groupsets as well as hydraulic shifting and braking setups.
Shielded seatstays promote smooth airflow and give the bike a wind cheating advantage over competitors. Upfront and the Cervelo FK26 UL is stiff, compliant and creates little in the way of drag.
The Rotor PF-30 BBright™ bottom bracket shell is now 6% stiffer than ever before providing even more direct power transfer to the pedals.
The S5 uses only the finest finishing kit, with Mavic providing the stiff, lightweight, responsive and aerodynamic Cosmic Elite S Wheels, Mavic also supplies the grippy, durable Mavic Yksion Comp tyres and Italian saddle specialists, Fizik, have added their ultra-comfortable, high-performance Antares saddle.
Cervelo and FSA add the finishing touches, with an FSA OS-99 stem and Cervelo, All-Carbon, Aero handlebars, stiff, lightweight, to provide a comfortable but direct ride.
Ideal for road racing or triathlons, the Cervelo Aero seatpost offers two positions to allow you to dial the perfect position. Either a more relaxed 40 millimetre or an aggressive 0-millimetre setup is achievable.
