The new S5 has reduced drag by 65 grams,
and increased the frame’s surface area while still reducing overall weight.
The deeper frame sections maximize the shapes allowed.
The iconic V-stem has been further refined and a new fork designed to simplify the entire front end.What’s more, a ground-breaking new wheel design concept has been
co-developed with Reserve to increase stability and reduce drag
in turbulent aero conditions.

Cervelo S5 Ultegra Di2 Carbon Road Bike 2023 - Sapphire/Ice

Season:2023

Brand:Cervelo

Code:0I0S5FUI2C

V IS FOR VELOCITY

In pursuit of speed, everyone wants to try different positions to find their most aggressive fit.
The S5's iconic V-stem not only inspires confident handling at high speeds,
it's now also remarkably simple to dial in your perfect set-up.
All the necessary spacers come with the bike, and there’s now only one bolt length,
reducing complexity and making the system 53g lighter in the process.

FRAME ENHANCEMENTS

The UCI’s new regulations on aerodynamic design allowed us some additional room to
deepen Cervelo's aero profiles 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 more aggressive shaping on the
trailing edges of the tubes. Since the new S5 is only compatible with electronic shifting,
Cervelo were able to tidy the dropout a bit, and update the shaping all over the bike.

TURBULENT AERODYNAMICS

Reserve and Cervélo put our heads together to develop a completely innovative way of
engineering and testing wheels to perform optimally in turbulent aerodynamic conditions.
Wind tunnels usually measure performance in ideal "laminar" flow situations.
But such conditions are unrealistic in the real world.
So Cervelo helped Reserve develop rim profiles that stall less dramatically at greater yaw angles;
in riding terms it’s more stable, more planted, and thus 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.


TIRE CLEARANCE

Wider wheels and tires are faster aerodynamically, and more comfortable to boot.
S5 comes specced with 28mm tires but has clearance for up to a 34mm (measured) tire.
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.

HANDLEBAR REFINEMENT

Cervelo have improved the comfort of the handlebar, and tweaked the shape to get a
perfectly flat bar-to-hood transition.
Cervelo now use a two-bolt interface that allows for infinite tilt adjustments
between 0 and 5 degrees.

KEEPING IT SIMPLE

Bike fitters at every level are moving away from longer-offset seat posts,
and the new S5 comes stock with a 15mm offset post on most sizes (vs 25mm offset on outgoing S5).
The old seat posts are forward-compatible, and Cervelo keep the 400mm-long,
25mm offset post in stock for those looking for a more extreme fit.

MAKE FRIENDS WITH THE WIND

You can, in fact, reinvent the wheel. Meet Turbulent Aero,
a unique R&D program that leverages real world wind data to create the most rapid,
stable, and best handling wheels in real world riding conditions.
