R3 Disc Ultegra Di2 R8070 Complete Bike
We place some high priorities on a frameset when we go new bike shopping. Most often we place stiffness, weight, and handling values at the top since those things are usually solidified. Sure aerodynamics matter too, however, we know our wheels, clothing, and helmets choices will make as much, if not more, of an improvement at cutting drag than the frameset. We also really like the aesthetics of a more classic road frame over the hyper aero rigs on the road today. If you feel the same way and want the precise shifting and powerful braking of Shimano's Ultegra Di2 electronic group, we'd urge you to have a look at the R3 Disc Ultegra Di2 R8070 Complete Bike. It features a stiffness to weight ratio that’s favored by World Tour riders and a refined geometry that can add a bit of calmness in a chaotic peloton.
The R3 is no stranger to the limelight. Consistently a winner in bike shootouts and with numerous editor choice awards to its credit, it also has a Tour victory to its palmarès under Carlos Sastre and was the first bike to enter the Roubaix velodrome under the likes of Cancellara, O'Grady, and Vansummeren. This tells us a few things. The frameset is durable enough to handle brutal cobbled roads, it's light enough to scale hors catégorie climbs, and it's comfortable enough for a 3-week stage race or a 6+ hour one-day classic.
There's no need to fear any climb when aboard the R3. The frameset is built using special carbon layups and construction techniques, allowing Cervelo to reduce the frame's weight while making it stiffer at key points. This remarkable stiffness to weight ratio means the R3 is agile and responds instantly to pedaling efforts and tracks through turns with authority. Cervelo 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 a 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.
The carbon layup is one area where Cervelo addresses the comfort issue. Another lies in its Elite Fit Road geometry, slotting in right between its Pro Fit Road on the R5 and S-Series bikes, and the Endurance Fit of its C-Series bikes. As such, it focuses on efficiency an allows for an easy setup of a variety of fits without compromising on comfort. Sure, its aggressive enough to race on, and often is, but not so much so that it's uncomfortable on all-day jaunts or stage races. As an added bonus, it clears 28mm wide tires where the added volume adds comfort and traction while reducing rolling resistance.
Returning Cervélo features include its BBright bottom bracket and Squoval Max tubing. It developed the wider BBright standard in an effort to increase stiffness by taking advantage of the real estate at the bottom bracket shell, seat tube, down tube, and chainstay. Additionally, it plays well with all major crank standards. Squoval Max tubing allows the design engineers the ability to use the best attributes of a square and oval shape to improve the bike's ride quality while minimizing weight and maximizing stiffness. Additionally, while not as out-and-out aero as its S-Series lineup, tube shapes and internal cable routing do serve as some aero tricks up its sleeve when you're driving off the front of the pace line.
Cervelo frames constantly evolve and the brand constantly scrutinizes materials, shapes, and layups in an effort to boost stiffness, improve ride quality, and drop grams. Compared to previous generation R3s, this version is 16 percent lighter, has a 16-gram reduction in aero drag, and it's 4 percent stiffer at the head tube and bottom bracket to channel all of your power directly to your rear wheel and descend with confidence.
Finally, we love the small details that make a Cervelo a Cervelo. Things like its Future-Proof Cable Management system allows for full compatibility across mechanical, electronic, and hydraulic brake and derailleur systems. Its interchangeable cable stops snap into the frame and is easily swapped out by hand to accommodate different builds. And for those that prefer tried and true mechanical shifting, you'll appreciate its Reduced-Friction BB Guide, which maintains a consistent curve for each cable path that avoids extreme bends or kinks. The result is significantly reduced friction, easier setup, smoother shifting, and longer service intervals.
This particular model is built up with the smooth shifting and ultra-reliable Shimano Ultegra Di2 group. Those shifters also house a master cylinder for the powerful hydraulic disc brakes. It's ready to go off the front of the group ride or toe the line of your next race with its 35mm deep Novatec carbon wheels. Finishing up the spec, Cervelo takes care of the cockpit duties providing the handlebar, stem, and carbon seatpost that are plenty durable and add a bit of value to the bike.

The R3 checks all the boxes for me. Lightweight to fly up the climbs, stiff to put down the power, disc brake for added security on the descents, and solid handling for pushing it hard. Cervelos attention to detail in design, and manufacturing was really evident to me on my time on this bike. The Geo is perfect for long hours, and lot of climbing. Being able to fit 28s is an added plus as well. The handling is fantastic, and leaves absolutely nothing to be desired. Lightweight and disk is the way of the future and the R3 fits the bill. For a stiff, comfortable, climbing machine you cant go wrong with the R3.

enough to make me question my identity
I'm a mountain biker, right? After riding the Cervelo R3 I don't know what to believe anymore. This bike it light enough to feel great climbing a canyon and has a smooth ride that feels comfortable going down a canyon at high speed. The di2 shifting can't be beat. I found myself looking down to make sure it had actually shifted because it was so smooth. This bike was really fast. If you decide you want to slow down for some reason, the disk brakes give a lot of confidence to those of us who are usually more knobby tire inclined. This bike has skinny tires, no suspension to be seen, and no dropper post. But riding it was really fun? What is happening? Who am I? I'm definitely a mountain biker... Unless?

I have had the Cervelo R3 disc to ride for the last week. Reasonably light (for a disc bike) smooth, clearance for 28c tires which are my jam and if you aren't on 28's then you are missing out on life, and stable. Handling is agile, quick without being nervous. I hit 59.9 mph which is 96.4 kph which sounds even more impressive and it never felt even remotely unstable. I was super impressed, especially because this was a 51cm frame, slightly smaller than my normal pick. Cervelo's focus on geometry with equal and excellent handling across all sizes was evident, typically your smaller and larger sizes suffer, but not with Cervelo. Di2 is fantastic by the way. If you want a true set it and forget it drivetrain, Di2 is the way to go. I have thousands of miles on Di2 and have never once had to make any adjustments beyond the initial setup. If you have the means, I highly recommend it.

Cervelo for years has been known for their aerodynamics and going fast. The R-Series takes things to the next level with its all-round ability. While 6K is no small chunk of change, what you get with the R3 rivals that of any top end offering. Sure you can find a stiffer or lighter bike but you'll be hard pressed to find a bike that gives you a measurable advantage over the R3 for under 10K. Or even over 10K for that matter. Riding out here in Salt Lake, I had the opportunity to test this bike out on all sorts of terrain, and I must say, I was impressed every time. Climbing steep canyons while never easy for me, the R3 handled great both in and out of the saddle. The 8070 drivetrain shifts under load without issue. Descending the Cottonwoods is always exciting and you can do it with confidence on board the R3. The Hydraulic disc brakes allow you to scrub speed as needed as well as enter corners without fear. Strong crosswinds can be terrifying and while they did move me around a little, I never found myself out of control. When it comes time to put some power down you will be impressed by how quickly it responds. Whether you are trying to catch the breakaway or simply trying to pass another rider in the bike lane you will have no trouble accelerating. At 6' with a 32 inseam I fit perfectly on the 56 The R3 will also look great at your local Cafe Stop!

Cervelo nailed it.
Cervelo makes bikes for people who know what they're doing. They're known for making the lightest, stiffest, most aero, etc. offerings on the market, and for taking a no-compromise approach to design. Cervelos of yesteryear were undeniably quick, but you had to be willing to endure a mercilessly stiff ride. This R3 was incredibly stiff and lively, but it was also one of the smoothest race bikes I have ever ridden. Witchcraft? Probably. Cervelo seems to have cracked the code to the code to the laterally stiff/vertically compliant riddle. Without an engineering degree, I can't aptly explain why, but as a rider, I can tell you that they nailed it. If you're reading this, there is an excellent chance that you're cross-shopping this with the R5. If you want one of the lightest, best handling race bikes in the galaxy, and you're willing to pay for it, it's the bike for you. If you want to be slightly more upright, and land a sweet deal, the R3 is the ticket! All in all, I'm extremely impressed. At $3k for the frameset, I'd buy this over almost anything else. As far as sizing goes, I'm 5'11, and while the 56 that I rode felt almost perfect, I could have gone down to a 54.
