Cervelo's offering of the Squoval.Max tubeset with the R5 Ultegra R8000 Bicycle is just one of several complete bike models for this special road race bike, and one designed to get more cyclists on this awesome frameset. One of the most important features of the current R5 has been bringing back the geometry to more of a pro-fit starting point, but having the ability to easily run 28mm tires at all times, even on 25mm wide rims. There is a marked increase in lateral stiffness in the frameset over the it's already excellent predecessor, as well as improved aerodynamics and overall ride quality. Cervelo aficionados will quickly identify the aero, square back seattube and seatpost. This R5 is shipping with a Shimano Ultegra R8000 groupset and a set of DT wheels so there are no compromises in quality. With Shimano's impressive shifting and braking, as well as improved ergonomics, this is a race-developed bike with high-level components for the serious enthusiast or racing cyclist whose budget is $5000.

The massive square-oval design of the downtube makes the most impressive statement about Squoval.Max, but every tube on the R5 has been redeveloped to reduce weight, increase lateral stiffness without compromising vertical compliance, and maximizing aerodynamics. From front to back, the redesign fortifies at junctions for increased torsional stiffness to the tune of 21% at the headtube junction and 13% at the bottom bracket, while increased shape integration delivers 14-gram improvement in aerodynamics. The bottom bracket has been lowered, with a 72mm drop, rising up in a D-shaped flatback seattube that carries to the top. The accompanying D-shaped Aero seatpost features a new rear fastening system, that gets hidden by a fitment that covers the entire junction, improving aerodynamics. The seattube/seatstay cluster exits out the back with a flattened section that adds torsional stiffness before reducing into the thin, vertically compliant stays the R-series bikes are known for.

The lowered bottom bracket, longer reach, lower stack, and shorter headtube of the R5 lengthen and drop the cycling position, in favor of a pro bike fit and weights the bike appropriately. This centers rider weight, but keeps the proper proportion over the front wheel required for aggressive corning and overall stability. The Cervelo carbon fork was built like the frame, with enhancements to the lateral base stiffness, tire clearance and aerodynamics. The end result is a bike that carves mountain descents, rips criterium corners, and rolls true and balanced on the flats. Increased comfort comes not only from the more compliant D-shaped seatpost, but also with larger volume tires. As aerodynamics research has pushed wheel manufacturers to wider rims, larger tires, and frame/fork air flow integration, cyclists have noticed that 25-28mm road tires can be fast, aero, and reduce road noise and impact. This race-ready R5 takes full advantage.

Cervelo's aero integrated Future Proof cable routing that accommodates mechanical and electronic drivetrains carries over, along with the Reduced Friction Bottom Bracket Guide. The derailleur cables or wires run down into headube/downtube junction from a port just behind the headtube, similar to the aero-road S5 design. One of the engineers' tasks with the R5 was to develop it, and the disc brake version, to be a close as possible in fit, function, feel, and frame performance. While the disc brake model features thru-axle drop outs, the standard R5 features traditional road 100mm and 130mm quick release versions. Again, this is catering to the pros, who predominantly ride dual-pivot caliper brakes, but also reduces overall bike weight (if not frameset weight)as well.

Second generation 11-speed Shimano Ultegra R8000 carries the improvements of the Dura-Ace R9100. The ergonomics of the STI levers were subtly but noticeably improved and gained a more positive lever response for additional shift reassurance, stiffness and aerodynamics of the world's best dual-pivot brake calipers increased power and feel with less drag, the front derailleur actuation lever and pivot were changed to be more compact, for better frame and tire clearance, and the new rear standard cage derailleur was updated to fly through shifts- even with a 11-30 cassette option. Along with the smooth powerful R8000 dual caliper brakeset, the drivetrain is nearly a full R8000 set-up, with the CN-HG701 chain, and 11-30 Ultegra cassette. The only alternative from Cervelo is the adaptive BBright Connect 24-90 bottom bracket for the 24mm Hollowtech II crankset.

Cervelo opted for a wide-ranging 11-speed drivetrain with the 52-36 crankset and the 11-30 cassette. The wheels are supplied by DT Swiss, the P1800 Spline 32m and equipped with Continental Grand Prix SL clincher tires in the 700x25 size. Cervelo supplies the square back SP18 carbon seatpost and the Ultra Light Alloy Stem. The alloy handlebar is the Cervelo Ultra Light AB07 Aero- which is finished with Cervelo bar tape. A Prologo Zero 2 STN saddle fits and suits many cyclists. Finally Cervelo provides an FSA IS-2 headset for the full carbon R5 Fork with the tapered 1⅛" to 1½" steerer tube.

Our take is that Cervelo has brought the R5 rim brake frameset back closer to it's pro race roots while modernizing and improving the model through engineering of the geometry and design, while making the frameset more performance responsive without compromising comfort. This R5 Ultegra R8000 Bicycle will bring a smile to the face of any rider who can ride it and push it to the limit and feel great about the Ultegra performance and price point, while rocketing uphill or in a sprint, while smoothly ripping corners of all varieties.
