The history and pedigree of Cervelo's R3 series bikes ensures that dedicated R3 riders have been scoping out the R3 Disc. The first generation frame hit most of the marks but Cervelo was already busy developing the SquovalMax tubeset, a new fork, and improving crucial aspects such as fit, handling and overall stability. The 2nd generation R3 Disc frameset now easily carries 28mm tires front and rear. Packaged here as a complete bike, featuring a full Shimano Ultegra R8000/8020 hydraulic disc brake groupset and a Mavic wheelset, the Cervelo R3 Ultegra 8020 Disc Bicycle seeks to set a new standard for value and performance in a road disc brake bike that rides like a dream and takes full advantage of disc braking.

Perhaps that is the best place to begin. The R3 Disc is a road disc brake bicycle. Not an allroad, gravel or endurance bike. The standard R3 after all is a road race style bike. Yes, you get a tapered 1⅛" to 1½" carbon fork. There are 12/100mm front and 12/142mm rear thru-axle dropouts. Flat mount standard caliper mounts fully integrate with the frame and fork, and yes the tire clearance is 28mm. These are features that actually suit the new road race approach. Yes, you can find many of them on gravel, endurance, and even XC race mountain bikes, but the same reasons they are effective for improved handling, ride quality, torsional stiffness and overall performance certainly carry to the road.

The full carbon disc fork rides into the matched tapered headtube that, along with the main frame tubes, ensures exceptional torsional stiffness under any load. The always evolving square-oval, or SquovalMax tubeset that features a flatter shape system and improved aerodynamics. The shapes and carbon lay-up improve the lateral stiffness by 18% over the first generation R3 disc frameset. The geometry has a lower standover height and improved toe clearance, improving overall stability, especially under braking forces from the hub mounted disc rotors. Wider tires at slightly lower pressures also improve handling, improve aerodynamics, and reduce rolling resistance. As a sub 1000 gram frame, the R3 Disc is still a superior climbing weapon- where the 18% stiffness really shines through, yet now is an even more capable descender and overall stable platform in all conditions.

A long standing key to R3 and other Cervelo bike's performance has been the 79mm wide asymmetric BBright bottom bracket design. Cervelo simply changes the carbon lay-up in the fork and frame, through the SquovalMax tubeset to adapt the set-up for disc brake use. Cervelo adds their integrated Reduced Friction Bottom Bracket Guide, and Future Proof internal routing and interchangeable stop system for hydraulic, electronic or mechanical systems. A braze-on front derailleur tab is used, and the rear thru-axle dropout features a replaceable rear derailleur hanger. Cervelo specs their SP-19 27.2mm diameter carbon seatpost on the R3 Disc, which best complements the ride quality and feel of the frameset.

As a complete bike, the R3 Ultegra 8020 Disc takes full advantage of Shimano's mainstay Ultegra R8000 11-speed mechanical drivetrain, which like it's Dura-Ace R9100 sibling features improved lever feel to the redesigned front and rear derailleurs. The rear can now handle an 11-34 cassette and the front offers great frame and tire clearance as chainlines get wider. The R8020 Dual Control levers are built for cable actuated shifting and hydraulic disc brake use. Cervelo specs the complete bike with the R8000 52-36 crankset and 11-30 cassette, so you get great road range. The supplied BBB BottomFit BBO-72, PF24 Threaded bottom bracket directly converts the BBright standard to the 24mm spindle standard used by the Hollowtech II Shimano crankset. The drivetrain is driven by the Ultegra level CN-HG701 11-speed chain. The hydraulic disc brake calipers the new Ultegra R8070 models for the flat mount standard, and Cervelo stays on-key with the new Ultegra SM-RT800 160mm disc rotors.

The wheelset is Mavic's Aksium Disc CL, which is a solid every day performer for training and the most likely place you will upgrade if you are a serious enthusiast or racer. Both wheels are 24 hole, laced 2x and feature Mavic's high quality QRM bearing system and the Center Lock disc rotor mount standard. Cervelo equips the wheels with Mavic Yksion Elite clincher tires in what is a generous 700x25 size. With good grip, excellent puncture protection, and smooth, long wearing ride, these are a great match for the wheelset.

Cervelo supplies the SP-19 Carbon Seatpost with the 25mm offset, and the Ultra Light Alloy Stem. The alloy handlebar is the popular FSA Energy Compact, which is finished with Cervelo bar tape. A Fizik Antares R7 graces the seatpost, and while it isn't for everyone, the Antares is one of Fizik's best selling designs, so it does fit and suit a great many cyclists. Finally Cervelo provides an FSA IS-2 headset for the full carbon R3 Disc Fork with the tapered 1⅛" to 1½" steerer tube.

The overall performance, in all conditions, of the R3 Ultegra 8020 Disc Bicycle will be appreciated and desired by many, especially those who have fallen in love with R-Series bikes over the years. Engineered to inspire, and challenge you to be a more complete rider, this R3 Disc take full advantage of the excellent Ultegra R8000/8020 groupset to deliver not only exceptional performance and ride experience, but also superior value.
