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.
