2017 Cervelo S3 Disc ETap

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.

With improved stiffness, aero performance, handling and control, the S3 Disc combines savage speed with pleasing versatility. Free from the design constraints of rim brakes, the S3 Disc has been re-engineered to be stiffer, lighter and more aerodynamic. In a word, to be faster.


Race-ready Stiffness - 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.

Aerodynamics -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.

Usability - 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.

S3 Disc Engineering - A completely redesigned chassis combines new, more robust airfoil sections with a rear triangle borrowed from our revolutionary Rca road frame. Cervélo's dropped Downtube enhances frame stiffness while the flattened trailing edge makes bottles an integral part of the bike’s airfoil design. Overall improvements focus on all the perks you want in a workhorse of a bike: Future-Proof cables allow for easy set up of internal electronic, mechanical, or hydraulic shifting and braking lines.
