S3 DISC - A WORKHORSE UNLEASHED
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.
S3 DISC ENGINEERING
A completely redesigned chassis combines new, more robust airfoil sections with a rear triangle borrowed from our revolutionary Rca road frame. Our 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 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.
R3 Disc - Beyond the Brakes
Cervélo doesn’t embrace new technology just because it’s available and popular. Integrating disc brakes into the Tour de France-winning R3 meant a lot more than simply slapping them on. First, the technology had to be on track for UCI approval — the R3 is a renowned road-racing force, after all. Then we needed time to test, test and test again to ensure the optimal balance in aerodynamics, weight, stiffness and all the other factors that separate Cervélo from the competition. Fact is, details matter when changes are made to iconic frames, which is why you can trust us when we say that the R3 Disc is well worth the wait.
"The R3 Disc is... well-thought-out, light, has aerodynamic flourishes, and is intended to be a high-performance bike." - Bicycling.com
Available: Size 48, 51, 54, 56
Cervelo C3 - Further, Faster
The C Series’ more value-conscious endurance model is the perfect fit for serious cyclists looking to get off the asphalt and extend their seasons. The C3’s increased tire clearance, a lower bottom bracket and longer chainstays inspire confidence on mixed surfaces while delivering a longer, more comfortable day in the saddle. Speaking of confidence, the C3’s top-of-the-line disc brakes deliver exceptional control without sacrificing performance.

C5 - Engineered To Endure
Cervélo has always pushed high-performance cycling to new heights, and is now taking it to new surfaces and seasons with the launch of the C Series platform. The inaugural model, the C5, is designed to inspire confidence through a new endurance fit that delivers predictable, stable handling. It combines the exceptional lightness and appropriate stiffness engineered into every Cervélo – including an all-carbon fork from the pioneering Project California team – with a uniquely integrated disc-braking system.
"...The C5 is a real hard charger. Its planted ride quality, combined with powerful Shimanodisc brakes, thru-axles front and rear, and large sticky tires, meant I could push pretty aggressively and still feel in control." - Bicycling.com
"The C5 performed especially well on high-speed descents, where I found myself enjoying the stability through turns instead of backing off as I might on a bike with more sensitive steering. " - GearPatrol.com
