Cervelo S3 Disc Ultegra 6800



Cervélo has 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 disc-brake technologies into the world championship-winning S3 they 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 their 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.


A completely redesigned chassis combines new, more robust airfoil sections with a rear triangle borrowed from their revolutionary RCA road frame. The 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.


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 Cervélo 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 dropouts, 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 other Cervélo disc platforms, this increases stiffness in the back end, leading to better handling in corners. They’ve also boosted bottom-bracket stiffness on the S3 Disc for better handling and power transfer to the pedals.

Also come in Red and Blue with White accents.
