R3 Ultegra Di2 R8050 Complete Bike
With road bikes becoming more and more specialized by the day, we're really glad that there are still some really good all-rounders out there like the R3 Ultegra Di2 R8050 Complete Bike from Cervelo. It's simply an ideal all-arounder that places a premium on stiffness to weight, without neglecting comfort, and has a proven track record in some of the biggest races. If it's time for you to take the plunge and go new bike shopping and you value a jack-of-all-trades machine with electronic shifting and the simplicity and weight savings that come with rim brakes, your search can end right here.
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.
We also love all of 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 version of the R3 is race-ready right out of the box. From the precise, electronic shifting of its Shimano Ultegra Di2 group to the 35mm deep Novatec carbon wheels, this bike is ready for fast group rides and longer weekend jaunts. 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.
