This 58cm 2017 Cervelo C5 Dura-Ace Di2 9070 Disc Bicycle DEMO was built for photo and demo purposes and has been ridden. The steerer tube is at max allowable length, with spacers. Wear is minimal to moderate, but it is in excellent conditional overall and fully functional condition. We reassembled, inspected and tested this bike for full functionality.

Cervelo has carried many technologies and design cues from the R Series frame development to the endurance lineup of the C Series. The C5 gets the premium UD carbon fiber with a greater concentration of high modulus directional fiber in the frame and fork for greater lateral stiffness and power transfer- which is truly the only difference from the C3 model, but well worth the price in crease if higher performance performance is desired. The geometry, frame and fork clearance, and ride characteristics have all been engineered for long hours on the bike, on pavement, gravel, or mixed terrain. Flat mount disc brakes and thru-axles provide the control and confidence you need to push boundaries. You can easily run 28mm tires with fenders, and cable routing is internal and Future Proof. It is possible many 700x30 tires will fit without fenders, but that can be dependent on tire manufacturer and rim width. Now, with fantastic options for lightweight, high performance hydraulic road disc brakes, and an evolving understanding that not all cycling enthusiasts have a secret desire to race, or even just limit daily riding to paved roads, the C Series steps in to deliver incredible performance, comfort, and capability.

The Squoval tube shapes found in the C5 Ultegra were developed for the R Series road bikes then adapted to the requirements of the C-series. The combination of square and oval shapes were combined into a tubeset that is lightweight, torsionally stiff, vertically compliant and more aerodynamic than many "aero" road bikes. Squoval tubes resist bending and torsion, and when the carbon is laid up properly, compliance is built in. Any rider who has spent time on an R3 can attest to the incredible ride quality and performance- and this design is more compliant. The full carbon disc thru-axle C5 fork design uses a 1 1/8” to 1 1/2” tapered steerer to deliver more strength where it is needed- without gaining weight, and is properly matched to the stiffness and deflection of the 12mm thru-axle for stable disc brake power, wheel tracking and cornering feel. Strength and impact resistance has been bolstered with Kevlar around the bottom bracket junction, as well as in the lower part of the downtube. Cervelo also includes a removable downtube rock guard for protection from impact from loose rocks.

Geometry has been engineered for a balanced riding position and stable, responsive handling from a tall headtube, increased fork rake, longer chainstays, more relaxed headtube angle, and an increased bottom bracket drop. The design tracks well, corners more like a road bike than any other gravel bike we have ridden, and never feels edgy despite the taller headtube. Combined with the tubeset's superior ride quality and compliance of the thin, arcing seatstays, the geometry provides the rider with the necessary confidence to descend on gravel, whistle through the corners on pavement, and power through numbing miles on gravel roads that run straight as the eye can see. Cervelo is an engineering company at its very core, and every frame and bike design starts with an essential understanding of what the rider intends to use it for. Then the frame engineered and designed to meet and exceed those expectations. The frame and fork of the C5 are a perfect example of this process.

Shimano provides the Dura-Ace 9070/9000-level e-Tube wired Di2 electronic groupset for this C5 build, with the exception coming from the Rotor 3D30+ BBright 50-34 crankset and accompanying Rotor PF-30 bottom bracket. As many of you know, the Di2 ST-R785 mechanical shifter/hydraulic disc brake STI levers were developed to be shared between 1st generation Dura-Ace and Ultegra 11-speed groups. An 11-28 cassette delivers great range and standout Dura-Ace performance, with the Di2 9070 front and rear derailleurs driving the ultra precise and incredibly fast electronic shifting action through the HG900 chain. Hydraulic calipers are the BR-R805 flat mount versions, and the premium RT99 IceTech Freeza disc brake rotors come as 140mm front and rear. These brakes deliver exceptional stopping power through the 12mm thru-axle HED Ardennes Plus LT Disc wheelset. Rear wheel spacing is 142mm. The 25mm (21mm internal) Plus rims are Tubeless Ready compatible, and carries the stock Continental Grand Prix 700x28mm tires effortlessly.

FSA provides the front of the cockpit, with the K-Force Compact bar and OS-99 Carbon-alloy stem. The Fizik Antares VS Saddle is mounted to a round 27.2mm K-Force carbon seatpost. Geometry and components are specific to frame size, which runs close to standard for most cyclists. Keep in mind the taller headtube reduces overall standover height, even with the sloping toptube design. Our take on the C5 is straightforward. If you are looking for a fast, performance oriented endurance road bike with disc brakes, it is an ideal choice. For those who want to ride aggressive gravel or rally on hardpack trails and require tire volume over 30mm, this is not your best option. Yes, there is some specificity in bike choices. Cervelo has mastered aero, aero road, and road race. Now the considerable talents and experience of this engineering-driven company have mastered performance endurance with the C5 and the mechanical drivetrain/hydraulic disc brake combination in this C5 Dura-Ace Di2 9070 Disc Bicycle. It offers a great balance of features, capability and cost effectiveness with tremendous versatility and overall riding potential.
