S3 Ultegra R8000 Complete Bike

For us, Cervelo's S3 Ultegra R8000 Complete Bike represents the self-sponsoring road racer's bike. Its aero frameset is a surefire ingredient for going fast since aerodynamic drag accounts for as much as 90 percent of the overall resistance you encounter on a ride. Next up, Shimano mechanical Ultegra and rim brakes keep the value and reliability high so you can afford to go to races, plunk down on some carbon tubulars if you wish, get a powermeter, or pay for some coaching. It's certainly a bike that can grow with you and is worthy of upgrades down the road. We can't think of very many other bikes that are so well-rounded for road racing, crits, or that weekly club time trial, and if you want aero speed, a comfortable ride, stiffness and responsiveness for efficiency and positive descending, and a refined geometry focused on rider comfort and sure handling, meet your new bike.

Cervelo honed the S3's aerodynamics after spending countless hours in the wind tunnel testing and refining designs. This particular disc model features full internal cable routing thanks to a new bar and stem that hides the brake and shift housing from the wind for improved aerodynamics. Additionally, the new frame profiles work together to reduce drag so you simply go faster. Cervelo calls this True Aero which combines these specific tube shapes, sizes, and design features to improve aerodynamic flow across the bike.

The most aero bike available is meaningless if it’s a wet noodle though, so thankfully Cervelo worked hard to increase the stiffness at the bottom bracket shell ensuring efficient power transfer and that every watt goes straight to the rear wheel. Just like every other Cervelo, the S3 uses its BBright shell which takes advantage of oversized frame tubes that are stiffer and lighter. With the BBright system, larger sized tubes are used at the seat tube, down tube, and non-driveside chainstay. The benefit is an increase in stiffness and pedaling efficiency while achieving a lighter weight frame that's compatible with all major bottom bracket standards. Stiffness doesn't just end there and Cervelo beefed up the head tube junction that conspires with its geometry for more confidence inspiring handling with impressive stability and precision when cornering and descending at speed.

Cervelo's mastery of carbon layups and construction techniques also allow it to reduce the frame's weight while making it stiffer. It uses advanced engineering software like Finite Element Analysis (FEA) that allows it to better understand exactly how each layer of carbon fiber is working and if it's being used properly. Its carbon expertise prescribes a specific frame layup by placing hundreds of individually cut plies of carbon in a mold in a certain order and orientation. By precisely cutting these plies, the frame is able to be made lighter while still achieving the desired strength and reliability.

And because different areas of the frame experience different loads while climbing, sprinting, and descending, to better cope with these forces, Cervelo creates different layups by placing the fibers at different angles in specific areas for the desired metrics. In addition to reducing weight, maximizing strength and stiffness, it's also instrumental in how comfortable the bike is to ride and it's backed up with extensive in-house testing and real-world experience.

A fast ride is a smooth one and it's important to keep vibrations at bay if you plan on going fast for long periods of time. Excessive road noise transmitted to the rider has proven responsible for premature fatigue and since Cervelo uses specific frame lay-ups and tube shapes that help soak up road vibrations, it helps reduce fatigue on those long days in the saddle.

Lastly, this S3 save 102 grams or the equivalent of 13 Watts, over the previous version of the S3 disc. It's also 68 grams lighter for less mass to haul around.

This build is value packed with Shimano's Ultegra mechanical shifting for positive shifting and durability for many seasons to come. DT Swiss P1800 Spline 32 wheels also keep the value proposition high and further adds reliability and durability to the build. Rounding out the build, cockpit components are from Cervelo that add a bit of aero integration to the bike while keeping costs low.
