WORKHORSE UNLEASHEDHOW CERVÉLO UNLEASHED ITS AERO WORKHORSE

THE CHALLENGEDisc brakes are becoming increasingly popular owing to superior modulation and all-

weather performance, but better braking isn’t enough for the S3 Disc. After all, it

is Cervélo’s policy to only introduce a new bike when significant gains in design and

technology have been achieved. For this reason, our newest disc model had to equal or

surpass the S3 in all five of the performance criteria encompassed by our Engineering

Fundamentals: Weight, stiffness, ride quality, usability and most importantly, aerodynamics.

AERODYNAMICS

GRAM AERO ADVANTAGE OF THE S3 DISC

19The S3 Disc is an aero speed machine first and

foremost, so superior aerodynamics topped our

to-do list. The all-new S3 Disc fork features a

re-engineered leg airfoil that’s 19g (~2 watts)

faster than an equivalent S3 fork. The disc

braking system also allowed our engineers to

raise the fork crotch to reduce the low pressure

zone behind the crown, while widening the stance

of the legs to better blend with the caliper-

mounting area and fine-tune interactions with

the front wheel.

STIFFNESS

As with our other disc platforms, 12mm thru-axle technology boosts

stiffness in both the back-end and in the fork, leading to better handling

in corners and an 8 per cent increase in headtube stiffness. We’ve also

boosted bottom-bracket stiffness by 9 per cent to improve overall

handling and power transfer to the pedals.

USABILITYA redesigned cable routing system takes the signature side-entry cable routing system

of the S3 and incorporates a new style of left-side entry to accommodate the hydraulic

hose while providing a tidy access point for wired electronic shifting systems. Just one

more detail to which Cervélo has paid careful attention. We also imported the internal

battery mounting feature from the Cervélo S5 in order to better conceal the Shimano Di2

battery inside the downtube, with access through the BB cable guide mounting hole.

RIDE QUALITYRe-engineered seatstays and chainstays, inspired by the Cervélo R3 Disc, have been

optimized to work in tandem with the disc brakes to provide the best possible control

and handling. New rear drop-outs, meanwhile, use thru-axles to create a stable and stiff

wheel-to-frame junction with better brake alignment.

WEIGHT

GRAM WEIGHT SAVINGS OF THE S3 DISC FRAME

40By making the most of lightweight frame

and fork design rooted in our Project

California research facility, the S3 Disc frame

is 40 grams lighter than than the S3 frame.

BUILDS AND KEY FEATURESThe S3 Disc features identical geometry to

the S3, with classic road handling and fit.

Two Ultegra builds — Di2 6870 and 6800

— deliver durable, premium performance,

while two eye-catching colourways will

turn heads on the road.
