2018 S3 DISC ULTEGRA Di2 8070 White
"With improved stiffness, aero performance, handling and control, the S3 Disc combines savage speed with pleasing versatility."
We’ve taken everything that makes the S3 such an aero class leader and made it stronger, stiffer and ultimately, faster. Cervélo only launches a new bike when significant performance gains have been made, and by integrating our disc-brake technologies into the world championship-winning S3 we have done exactly that. The S3 Disc is stiffer and more aerodynamic than its rim-brake counterpart, while continuing to make the most of the lightweight design rooted in our Project California research facility. All of this translates to superior handling and control, giving you the confidence to pull away from the peloton or put the hurt on a Saturday morning group ride.
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.
Re-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 12mm thru-axle technology to improve performance still further, while creating a stable and stiff wheel-to-frame junction and yielding better brake alignment. As with our other disc platforms, this increases stiffness in the back end, leading to better handling in corners. We’ve also boosted bottom-bracket stiffness on the S3 Disc for better handling and power transfer to the pedals.
A 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 bottom-bracket cable guide mounting hole.
Sram eTAP and two Ultegra builds — Di2 8070 and 8020 — deliver durable, premium performance, while two eye-catching colourways will turn heads on the road.
