    S3 Disc Ultegra Di2 R8070 Complete Bike

    The influx of aero bikes in the pro peloton comes down to two reasons. First, the sport's governing body, the UCI, places a minimum weight limit that bikes must adhere to, and instead of mechanics adding dead weight to make a bike compliant, bike manufacturers are finding ways to add some functional weight to the bike with tangible benefits, so aero tubes that lower drag makes total sense. The other is because the speed of sprints, break always, and the chase to bring back those breakaways, are so high, the pros are looking for ways to make their jobs easier and science tells us that aero drag accounts for as much as 90 percent of a rider's overall resistance. Less drag equals more speed and the benefit happens at lower speeds than you might think as well as on single-digit gradients. So if you're looking for an advantage in a day-long breakaway, while sprinting, or want a do it all machine for the weekend omnium, we'd suggest looking at an aero rig if you are new bike shopping. And if you want to be up to speed on the newest tech such as electronic shifting and disc brakes, look no further than the S3 Disc Ultegra Di2 R8070 Complete 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, the S3 Disc is 102 grams or the equivalent of 13 Watts faster than the current rim version of the S3 completely dispelling the myth that disc brake bikes are less aero than rim versions, while also coming in 68 grams lighter, again smashing another disc brake rumor.

    This particular version comes ready to race. Shimano Ultegra Di2 shifting is accurate and precise with every shift and its hydraulic disc brakes easily scrub speed whether it’s a four-corner crit or a high-speed mountain descent. Even the Novatec R5 Carbon 48mm Disc wheelset is optimized to give you an aerodynamic edge on fast group rides and races.

    Race Machine

    Familiarity:I've used it several times

    Cervelo has long been a leader on Aero technology and frame design, and you can see that in the S3. From the clean integrated cockpit, to the aero tubing, and seatpost this bike is designed to go fast. Super stiff around the BB, so the power transfer was great. That stiffness paired with the Geo gives great quick, responsive handling. Even though this frame is not necessarily designed for climbing, its no slouch. It felt right at home on a 6k climbing day for me. The stiffness does provide for a harsh ride at times. If your roads are particularly rough, I would say perhaps to look in a different direction. All in all, this is a phenomenal race bike. You won't be dissapointed. I'm 6 3 and rode the 58, and 61. 58 felt best out of the two!

    Low & Pro

    Familiarity:I've used it several times

    Let's face it, aero is in when it comes to features that are desired on new bikes nowadays. I made up my mind a while ago that a few watts saved here or there based exclusively on aerodynamics doesn't mean a whole lot to me, especially if it comes at a cost of comfort in the saddle. That is, until I spent some time on the S3.. Upon picking up the bike, it felt a little weighty, probably on the side of 8.6 (ish) Kg. that's a rough estimate, not weighed on a scale. Hopping on the bike was a whole other story. Saddle & geo felt extremely comfortable - carbon layup felt stiff in the pedal strokes, with not a major difference from other carbon bikes when going over harsh(er) gravel. No complaints about cockpit or touchpoints on the build - aero bars were fine when my hands were on the tops during climbs. nothing fussy with the internal seatpost. Internal wiring makes the bike look exceptionally clean, and not having floppy wires aids to its' aero claims. Ride quality was pretty fantastic overall. I found myself grinning ear-to-ear on flat sections, as I was riding 2 - 3 mph faster without notice. Descents felt extremely fast & confident through corners, disc brakes only accentuating that confidence in late braking. Build kit was stellar, Ultegra Di2 NEVER failed in all shifting - even when testing some front shifts under load. I didn't necessarily feel like I could "dance" up climbs as well, but every pedal stroke provided excellent power transfer - making it a candidate for hilly or even mountainous terrain/climbs. I'm 6'3" weigh 170 (ish) - rode a 61cm build. Felt very comfortable and could probably take some spacers out if I wanted. If I wanted to go full race mode, I would size down to 58cm.

    Feels Aero but is heavier than expected

    Familiarity:I've put it through the wringer

    I love the geometry. It seems to be a good middle-ground for a race geometry. Not super aggressive but not too upright ether. For a Ultegera level bike at 7k, it should have had nicer wheels. I am not happy with the Novatec they felt sluggish. I swapped them out for a pair for Black inc 55s and I am happier with them. My S3 is size 54 and with only Vector pedals and cages weighs in at 19.3lbs. Which I think should come in at under 18lbs for a bike at this level. One thing to be aware of with a lot of these bike with proprietary stems is that in order to change the stem or headset bearings, you will have to disconnect everything from the cockpit including the brake lines. So if I had the chance to do this again, would I buy an S3? Unforutanly the answer is probably not.

    I

    Wow, something must have happened between 2018 and 2019 models. I have a 51cm 2018 S3 SRAM Red eTap (11 spd) hydro disc brakes that came with ENVE SES 5.6s. With pedals and bottle cages it weighs 17lbs 12oz (weighed at bike shop using their calibrated scale).

    Aero

    Familiarity:I've used it once or twice and have initial impressions

    If you are in the market for a stiff aero race steed you owe it to yourself to checkout Cervelo's S3 disc. The fully internal wiring setup of the Shimano Di2 R8070 drivetrain gives this bike a super clean cockpit free of wires and housing. Impressive stopping power gives you confidence heading into the turns as well as helping you avoid that careless driver (which I discovered firsthand on my first ride). Your can really put some power through this bike. It accelerates on command and handles better than I would have expected. Descending the steep canyons here in Utah is a breeze and you can hold your line in cross winds without too much trouble. Sizing for Cervelo is based on Stack and Reach which makes it easy to get you on the right frame size. The 56 fit me perfectly at 6' and a 32" inseam.
