S5The New S5
Cervélo is well known for our dedication to aerodynamics
and relentless pursuit of speed. Ever since the creation of
the Soloist in the early-aughts, we’ve been redening what
an aero bike can be. The new S5 continues in this vein,
and exemplies our mission to make riders faster.
You’ll see deeper frame sections to maximize the shapes
allowed by the UCI, a new fork design that helps simplify
the entire front end, and increased wheel/tire clearance that
makes space for the new Reserve 52/63 wheelset, which we
co-developed to deliver an even faster bike. Altogether,
we reduced drag by 65 grams, and increased surface area
while still reducing the bike’s weight. It’s simpler, faster, and
easier to live with than before.
In pursuit of speed, everyone wants to try a different position,
a longer stem, a more aggressive t—these swaps were intensive
on the previous S5. On the new one, it’s as easy as installing the
new stem. All the necessary spacers come with the bike, and
there’s only one bolt length, instead of the previous stack-specic
bolt spec. The handlebars attach more simply, and have a
5-degree rotation to dial in your t. Reducing all that complexity
made the system 53g lighter, too.
We’ve improved the comfort of the handlebar, and tweaked the shape to get
a perfectly at bar-to-hood transition. In place of the shims on the previous
S5 handlebar, we’ve used a two-bolt interface that allows for innite tilt
adjustments between 0 and 5 degrees. Bike tters 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 we’ll keep
the 400mm-long, 25mm offset post in stock for those
looking for a more extreme fit.
The UCI’s new regulations on aerodynamic design allowed us some additional room to deepen
our aero proles and squeeze a little more 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,
we were able to tidy the dropout a bit, and update the shaping all over the bike.
Wider wheels and tires are faster aerodynamically, and more
comfortable to boot. S5 has clearance for up to a 34mm (measured) tire,
and is optimized around the new, wider Reserve wheels, which are
wrapped in 28mm tires. These wheels, developed under Turbulent Aero
protocols, save a little over 5 watts.
The real advantage to Turbulent Aero is the way the wheel behaves in—you
guessed it—turbulence. Put another way, what it does when there’s wind
blowing. Which is usually. Reserve and Cervélo put our heads together and
developed a rim shape that stalls less dramatically at greater yaw angles;
in riding terms it’s more stable, more planted, and more comfortable.
It requires less input and attention from the rider, and contributes to rider
condence. It makes you go faster because you feel more comfortable going
faster. The Reserve 52/63 is 50g faster in laminar (traditional) ow, and 54g
faster in turbulent ow than the outgoing Reserve 50/65 combo.
