Details

Cervelo's S5 VWD is as aero as a sliver and as light as a whisper. It begins with a carbon layup that’s tuned to optimize stiffness laterally and torsionally while shaving every gram possible. Cervelo’s aero geniuses hit high gear with a dropped down tube and an extended rear wheel cutout to smooth the transition of air from the front to rear wheel with nary a hiccup. The wind-cheating wizardry continues with an hourglass head tube and internal cable routing with top-tube entry. Cervelo’s mammoth BBright bottom bracket provides Herculean power transfer while their renowned geometry means it’s as comfortable as it is responsive and fast. Shimano's flawless Dura-Ace Di2 makes shifting effortless with the tiniest tap of a finger. This rocket is built with Mavic's Cosmic Elite wheelset, hyper-stiff Rotor 3D+ crankset, powerful Dura-Ace brakes, 3T Team components, and Fizik's Antares saddle.

Lightweight carbon fiber bulkheads at strategic locations (down tube at head tube, seat tube at top tube, above the bottom bracket shell) brace the walls, boosting stiffness while adding less weight than would be needed to thicken the walls. Net result: 2.2 grams lighter and 6% stiffer. 

ICS3 (Internal Cable Stops) erradicates the need to run internal cable housing the entire length of the tube, which adds friction and up to 200 grams of dead weight.

Internal Cable Stops on the other hand, function much like external stops. The housing fits into the stops and the bare cables travel in unobstructed paths through the frame, into the bottom bracket cable guide, and straight to the derailleurs.

ICS3 also reduces aerodynamic drag by placing the cable housing entry out of the wind behind the stem. In order to have the cables enter the top tube, yet travel unobstructed through the downtube, Cervelo's ICS3 frames use Teflon-lined stainless steel tubes, curved to guide the cables into perfect alignment with the Bottom Bracket cable guide.

A simple method to reduce aerodynamic drag is to remove or hide objects from the wind. In some cases a brake can be completely integrated into the frame structure as if it doesn’t exist at all. However, in other cases, there are practical limitations to this level of integration. One of the real world constraints of a road bike is that riders and mechanics need to have quick, easy access to most parts on the bike. Under these conditions, complete rear brake integration is problematic for road racing. An effective and practical solution is to position and shape the seatstays to hide the rear brake from the wind.  

Dropping the down tube “hides” it in dirty air, reducing the high pressure normally found on the down tube’s leading edge, and eliminating the low pressure air that normally pulls rearward on the fork crown.

Frames are but one component of an entire system. Cervelo considers your hydration needs as part of the aerodynamic equation. Two water bottles fit in the usual positions: one on the seat tube, one on the down tube. In the standard 2-bottle arrangement, the bottles fit together tightly with each other and the frame, reducing the gaps where turbulence can form for lower aerodynamic drag.

In addition, an extra bottle boss on the down tube creates a new lower position for a single bottle. Using the low position on the down tube saves 14 grams of aero drag, a reduction of about 1.4 watts, compared to a bottle in the usual position.
