Cervelo S5 Five Black 2023 Frame

Meanwhile, the iconic V-stem has been further refined and a new fork designed to simplify the entire front end.

In addition, an innovative new wheel design concept has been co-developed with Reserve to increase stability and reduce drag in turbulent aerodynamic conditions.

The new UCI regulations on aerodynamic design allowed us additional room to deepen our airfoils and squeeze 65 more grams of drag performance out of what is already the fastest aero bike on the market. You'll notice a deeper head tube and BB area, and a more aggressive shape to the trailing edges of the tubes. Since the new S5 only supports electronic shifting, we were able to spruce up the dropout a bit and update the shape on the entire bike.

Reserve and Cervélo have come together to develop a completely innovative way of designing and testing wheels to perform optimally in turbulent aerodynamic conditions. Wind tunnels often measure performance in ideal "laminar" flow situations. But such conditions are not realistic in the real world. So we helped Reserve develop rim profiles that stall less dramatically at higher yaw angles; In terms of handling, it's more stable, firmer and therefore more confidence-inspiring. It makes you go faster because you feel more comfortable going faster. The Reserve 52/63 is 50g faster in laminar (traditional) flow and 54g faster in turbulent flow than the outgoing Reserve 50/65 combo.

Wider wheels and tires are aerodynamically faster and more comfortable to launch. The S5 comes with 28mm wheels but has room for up to 34mm (size) wheels. The frame is optimized to complement the wider Reserve 52/63 Turbulent aero wheels. In addition to the handling benefits, this saves over 5 watts compared to the previous Reserve wheelset.

We have improved the comfort of the handlebars and adjusted the shape to obtain a perfectly flat transition between the handlebars and the hood. We now use a two-bolt interface that allows for infinite camber adjustments between 0 and 5 degrees.

Bike builders of all levels are turning away from longer offset seatposts, and the new S5 comes standard with a 15mm offset seatpost on most sizes (versus 25mm offset on the previous S5). The old seatposts are backwards compatible, and we'll keep the 400mm long 25mm offset post in stock for those looking for a more extreme fit.

In fact, you can reinvent the wheel. Meet Turbulent Aero, a unique R&D program that harnesses real-world wind data to create the fastest, most stable and best-handling wheels in real-world driving conditions.

The 2023 S5 Disc frame is designed to accommodate electronic gear groups that use connectors up to 6mm in diameter, so Campagnolo EPS is not compatible with this frame. Mechanical shift groups are also not compatible with this frame.
