S5: OUT-OF-THE-BOX SPEED 

The new S5 has revolutionized the aero road segment – again. It combines many incremental improvements across the frame to deliver one huge improvement to you: more speed. The model that BikeRadar calls “spectacular in terms of raw aggression and savage speed” now offers increased stiffness, race-ready geometry and improved ride quality to produce our fastest road bike ever.

BBRight:

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

Cervelo developed BBright to take advantage of the fact that oversized frame tubes are stiffer and lighter. On the right side, frame tubes are already as wide as possible; any wider and they’d hit the chainrings. But on the left side there are no chainrings, so BBright makes use of this extra space by extending the BB shell by 11 millimetres, nearly doubling the width of the left chainstay. At the same time, the drive-side dimensions of the frame are identical to BB30 and provide plenty of clearance for a wide range of cranks, including those with power meters.

Built for Bottles:

Minimizes the aero penalty by partly integrating the water bottle into the downtime airfoil 

Cervélo models that are Shaped for Bottles have an airfoil downtube that’s flattened on the trailing edge in front of the bottle, resulting in a faster overall system.

Dropped Down Tube: 

Reduced drag by treating the front wheel and frame as one aerodynamic shape.

Improving aerodynamics requires an engineering approach that accounts for the entire system: Bike, rider and wheels. The Dropped Downtube places the leading edge of the tube closer to the trailing edge of the front tire, partly hiding it in the wake of the wheel.

Extended Seat Tube Cutout

A close fitting curve in the seat tubes trailing edge significantly improves aerodynamics by shielding the leading edge and top of the rear wheel.

Cervélo pioneered the Extended Seat-Tube Cutout, and we do it better than anyone. In order for it to be effective, the tire must fit closely to the frame and the seat-tube cross-section must have the right shape to help air flow smoothly across the seat-tube and around the wheel.

Future Proof Cable Management:

Ensures your frame is compatible with all current and future derailleir and brake systems.

Future-Proof Cable Management achieves compatibility across mechanical, electronic and hydraulic brake and derailleur systems. Future-Proof frames include interchangeable cable stops that snap into place and are easily swapped out by hand to accommodate upgrades. You can buy with confidence, knowing your bike is easily upgradable and can be enjoyed with the latest technology for years to come.

Carbon Dropouts:

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

Seatstays and chainstays are bonded into hollow dropouts, instead of the other way around. Bonding these precision-moulded surfaces reduces weight, and gives the internal rear derailleur cable a straight shot through the chainstay and dropout, eliminating bends and cable friction.

Evolved Steerer Design:

The fork steerer’s diamiter has a noticeable effect on a bikes handling. Evolved sterer design applies the diamiters and taper designs that best suit each model 

A larger steerer diameter adds torsional stiffness with no weight penalty. A smaller steerer diameter is more compliant and can also be used to reduce headtube frontal area, and in turn, aerodynamic drag. How do we select which size to use? By defining performance goals — weight savings, aerodynamics, stiffness, ride quality and usability — at the start of the frame design process, Cervélo engineers choose the best steerer diameters/tapers to achieve those objectives.

Shielding Seat Stays: 

Hide the rear brake calipers from the wind, not from the mechanic. 

Properly formed seat-stays improve airflow over callipers without complicating access and service.

Reduced Friction BB Guide: 

Significantly reduces cable friction in the bottom bracket, which means smoother shifting, easier set up and longer service intervals. 

The Reduced-Friction BB Guide maintains a consistent curve for each cable path by avoiding bends or kinks.
