TrueAero combines specific tube shapes, sizes, and design features to improve aerodynamic flow across the bike.


While opening a Clif Bar, we dropped down to this stance with arm warmers on, and nearly slid off the front of the bike. Exacerbating the situation is the absence of bar tape.

Using special frame tube shapes and design features, we improved the aerodynamics of the S5 Disc so you can reap the benefits of reduced drag.The stiffness of the S5 is a sprinter's dream. The bike doesn’t handle like a novelty; it rides like a race bike.A few other test riders at Cervélo’s Arizona launch commented that the bike seemed a little more comfortable than previous iterations. Handling markedly improved on a very aero bike, but aero-over-practicality bar choice is limiting Wheel Size They finally settled on a design that had, in Shrive’s words, “90 percent of the benefits with 20 percent of the weirdness.” We found the compact bend quite comfortable. Cervélo got out front early in the aero game, attacking the market in 2001 with its Soloist that evolved into the S5. HEADSET: FSA IS2 1 x 1-3/8. Already have an account with us?

Somewhat curiously, Cervélo chose not to use the new Direct Mount brakes, saying they made frame manufacturing overly complex without any additional aero benefit.Wheels have always been a point of discussion for Cervélo, internally and externally. We never once wished, ‘if only the small ring was Shimano’s Dura-Ace Di2 9070 group is best in class. 5 Titan Drive, Fengate East, Peterborough, PE1 5XG Search by postcode: Specs.

Cervélo S5 Dura-Ace Di2 review. No bar tape equals no grip. Reviews

2014 Cervelo S5 Carbon Road Bike 56cm Dura-Ace Di2 7970 Mavic Ksyrium Elite. The new bikes get the new 3D+ cranks with 52/36t ringsA massive bottom bracket area delivers aero benefits and torsional stiffnessThe 25mm-wide Hed rims plump up the 23mm GrandPrix clinchers. In shape, it largely is, but a few critical details have changedThe old S5 mounted the Di2 battery on the chainstay. For 2015, Cervélo engineers addressed those latter two points; front-end stack numbers are now in line with competitors’ race bikes, and We tested the new S5 Dura-Ace Di2 build over two days in Arizona.

Standover Height Watch. 20 watching. Cervélo lead engineer Graham Shrive said that comfort is harder to quantify than stiffness. Even on a cool day, palms on bare carbon will sweat, making for a slippery interface. The question, though — as with bikes, helmets and rider position — is how to strike a balance between aero gains and all the other desirable qualities. Skip to view product specifications Cervélo started the aero road bike genre, and they’re still very much at the forefront with the S5.

To that end, Cervelo sent us their S5 Ultegra. Sign up to receive our newsletter! Somewhat curiously, Cervélo chose not to use the new Direct Mount brakes, saying they made frame manufacturing overly complex without any additional aero benefit.Wheels have always been a point of discussion for Cervélo, internally and externally. El modelo 2020 pertenece a la tercera generación de S5 y es la bicicleta con mayor rigidez y aerodinámica hasta el momento, sin dejar de banda un buen confort en marcha y facilidad de uso. But while the last iteration of the S5 delivered impressively low-drag numbers in the wind tunnel, its front-end handling was a little wishy-washy and the head tube was curiously tall for a bike hellbent on race performance.

According to company CFD calculations, a bike’s handlebar contributes roughly 30 percent of its total drag. Magazines

We never once wished, ‘if only the small ring was Shimano’s Dura-Ace Di2 9070 group is best in class. Anywhere we could have looked at comfort we have.”In our experience, the S5 may have been a touch more compliant than the last iteration, but this could well have to do with the girthier clinchers and a seatpost clamp design that allows a little cantilevering in the saddle.Why Rotor cranks and not Shimano Dura-Ace, you ask?

When looking at a bike from the front, this makes sense. Frame lay-ups and tube shapes, along with tires up to 28mm wide, soak up road vibrations for a smoother ride.The new S5 is 42 grams faster than its predecessor - that's the equivalent of 5.5 watts.25% increase in bottom bracket stiffness over the previous S5, with six stem lengths, four bar widths, 5° of rotation, and up to 32.5mm of stem spacers. 15 watching. Using a combination of material, shape, and lay up, we engineered the S5 to be stiffer at the head tube, for stable and predictable handling, and at the bottom bracket, so that more of your power goes into turning the rear wheel.13% increase in headtube (torsional) stiffness over the previous S5The S5 is the pinnacle of "system thinking" whereby multiple Cervélo engineers are assigned specific areas of the bike's design in order to focus on perfecting each detail.
Finally, the pièce de résistance, the All-Carbon, Aero Handlebar. Design Watch.
