BICYCLE CERVELO S5 DURA-ACE DI2 28

BICYCLE CERVELO S5 DURA-ACE DI2 28

The S5 has a single task: to reach the finish line before everyone else. Under the leadership of Wout van Aert, Marianne Vos, and Christophe LaPorte, the new model has already proven to be an unparalleled instrument. In the 2022 Tour de France, this bicycle pushed Wout to achieve the highest points total in the modern era points classification. At 480 points, Wout had about 194 points lead over his nearest rival: tangible proof that Cervélo continues to provide aerodynamic advantages to its World Tour athletes.

The new S5 has reduced aerodynamic drag by 65 grams and increased the frame surface, while reducing total weight. The deeper sections of the frame maximize the shapes allowed by the UCI. The iconic V-stem has been further refined and the new fork has been designed to simplify the entire frontend.

Additionally, in collaboration with Reserve, a new and revolutionary wheel concept has been developed to increase stability and reduce aerodynamic drag in turbulent conditions.

CERVELO S5 DURA-ACE DI2 28 MAIN FEATURES:

• V stands for Speed: In pursuit of speed, everyone wants to try different positions to find the most aggressive setup. The iconic V interface of the S5 not only guarantees safe high-speed handling, but is now also exceptionally easy to adjust. All necessary spacers are supplied with the bike and there is now only one bolt length, reducing complexity and lightening the system by 53 g.
• Frame improvements: The new UCI aerodynamic design regulations have allowed greater freedom to refine aerodynamic profiles and achieve 65 g more aerodynamic performance than what is already the fastest aero bike on the market. Notable are a deeper head tube and bottom bracket area, as well as a more aggressive shaping of the tube exit edges. Because the new S5 is compatible only with electronic drivetrains, it was possible to simplify the dropout area and update shapes across the bike.
• Turbulent aerodynamics: Reserve and Cervélo collaborated to develop a completely innovative approach to wheel design and testing, optimizing them for turbulent aerodynamic conditions. Wind tunnels typically measure laminar-flow performance, but such conditions are not realistic in the real world. We helped Reserve develop spoke profiles that stall less drastically with wider yaw angles: practically, this means greater stability, more grip, and more rider confidence. It makes you go faster because you feel more secure when increasing pace. The Reserve 52/63 are faster by 50 g in laminar flow and 54 g in turbulent flow compared to the previous Reserve 50/65.
• Space for tires: Wider wheels and tires are faster aerodynamically and also more comfortable. The S5 is equipped with 28 mm tires but has room for up to 34 mm tires (measured). The frame is optimized to pair with the wider Reserve 52/63 wheels suited for turbulence. In addition to handling advantages, this provides a savings of over 5 watts compared to the previous Reserve wheelset.
• Handlebar refinements: We improved handlebar comfort and modified the shape to achieve a perfectly flat transition between handlebars and controls. We now use a two-bolt interface that allows continuous adjustable tilt between 0 and 5 degrees.
• Simplicity: Bike fitters at every level are moving away from long-offset seatposts, and the new S5 is shipped with a 15 mm offset seatpost in most sizes (vs. 25 mm on the previous model). The old seatposts remain compatible, and we will continue to stock the 400 mm model with 25 mm offset for those seeking a more extreme position.
