Introduction
Welcome to the Cervélo family! Congratulations on choosing the Cervélo R Series classic road bike. Its ultra-lightweight engineering is designed to help you conquer climbs and enjoy speed and control on descents. The understated design allows performance to shine, offering a stable ride that responds to the road.
As with any high-performance vehicle, it's important to familiarize yourself with its features and service requirements. Please read this manual thoroughly before assembly or use. This document guides you through the unique features of the R Series and serves as a supplement to the assembly instructions provided by your component manufacturer.
Frame Features
A guide to your Cervélo R5 frame:
- Front derailleur wire exit hole (electric and mechanical)
- Rear dropout cable exit
- Down tube internal cable ports
- Bottom bracket cable port
Fork Preparation
Parts required: A. Stem Cap + 5mm bolt, B. Headset Spacers, C. Bearing Cap, D. Compression Ring, E. Bearings, F. Fork Insert, G. Two-Part Epoxy, H. Mixing Stick, I. Isopropyl Alcohol Wipe, J. Sandpaper (120 Grit).
- Apply grease to the bearing seats and install the upper and lower headset bearings into the head tube.
- Fit the provided fork into the head tube with the complete headset, required spacers, and the stem.
- Apply minimum pressure to ensure the assembly is fully seated. Mark the steerer tube at the top of the stem.
- Remove the fork and clearly mark the steerer tube 4mm below the first mark. Verify this measurement as it defines the cut line for the steerer tube.
Important Note: Your Cervélo frame and fork are designed to work together. Do not substitute a different size fork without consulting Cervélo Customer Service for compatibility confirmation. Avoid breathing dust created during cutting carbon composite materials.
Steerer Tube Cutting Guide: Use a saw suitable for cutting carbon and a cutting guide. Sand a bevel to the inside of the cut end of the steerer tube to fit the insert. Dry fit the insert to ensure it is flush with the cut end. Clean the steerer tube inside and insert outside with isopropyl alcohol. Mix the two-part epoxy and apply to the outer surface of the insert. Slide the insert into the steerer, rotating slowly until the flared end sits flush with the top. Wipe away excess glue with the isopropyl alcohol wipe. Allow to sit undisturbed for full curing. Warning: Do not attempt to fit the fork before curing is complete. Improper cutting can lead to severe injury or death. Do not exceed 50mm total spacer height, including the bearing cap.

Frame Preparation (Rear Derailleur Hanger)
Apply Loctite 242 to the fixing screws and tighten them equally to a maximum of 1 Nm. With the wheel installed, use a Derailleur Alignment Gauge to ensure the hanger is aligned parallel to the wheel.
Mechanical Cable Routing
It is recommended to install front and rear derailleur cables after the brake hose. These illustrations supplement manufacturer instructions; refer to component manufacturer's service center or website for details.
Insert plastic noodles into the Top Tube Cable Stop (Mechanical). Assemble shifter cables with ferrules. The rear housing inserts into the drive-side port of the Top Tube Cable Stop, and the front housing into the non-drive side. Ensure housing is long enough to arc smoothly from the bar, over the stem cap, and enter the top tube perpendicularly. The housing nests in the cable stop, with cables continuing into the frame via the noodles. Warning: Failure to use cable noodles may result in frame damage.
Route gear cables out of the bottom bracket cable port, ensuring they are not twisted. The front cable travels across the non-drive side slot towards the seat tube. The rear cable travels along the drive side slot and chain stay. Snap the Bottom Bracket Cable Guide into place. Install the Rear Derailleur Press-In Cable Stop. Install the rear derailleur onto the hanger as per manufacturer's instructions, cut housing to length, and attach the cable.
Electric Cable Routing
It is recommended to install electric cabling and junction points after the brake hose. These illustrations supplement manufacturer instructions; refer to component manufacturer's service center or website for details.
Route the down tube electric wire to the bottom bracket through the Top Tube Cable Stop (Electric). For wireless systems, use the Top Tube Cable Plug. With all wires inside, cap the bottom bracket access port with the Bottom Bracket Access Port Rubber Blanking Plug. Install the Rear Derailleur Wire Guide. For wireless systems, install the Rear Derailleur Blanking Plug.
Seatpost Assembly & Installation
The R5 uses a proprietary shaped seatpost. Do not use any seatpost other than the model provided by Cervélo.
- Apply a light coat of carbon assembly compound to the upper face of the Seatpost, covering the area around the adjustment slots.
- Locate the saddle rail between the upper and lower clamps, and place on the Seatpost.
- With alignment washers installed, attach the assembly to the Seatpost by tightening lightly greased fixing bolts, alternating turns. Once the saddle is adjusted, tighten fixing bolts to a maximum of 8 Nm.
Ensure the Seatpost Clamp Cover and Cover Mount are placed onto the seatpost and lightly fixed before installing the Di2 battery or inserting the post into the frame. Generously grease all internal surfaces of the Seatpost Clamp.
Press the Di2 battery into the R-Series Internal Battery Holder and attach the cable per manufacturer instructions. Insert the assembled battery and holder into the seatpost. Apply carbon paste to the frame and seatpost shaft. Insert the seatpost and Seatpost Clamp into the frame. Adjust height and torque the Seatpost Clamp to 8 Nm maximum. Position the Seatpost Clamp Cover Mount at the top of the frame surface and torque to 1 Nm maximum. Push the Seatpost Clamp Cover down and fit over the Cover Mount.
Frame Protection Installation
Install the front derailleur using the bolt provided with the derailleur, torquing to derailleur specifications. Install the chain catcher when installing the front derailleur. Complete final adjustment with the chain in the small chainring and largest cassette cog. Tighten the connecting bolt to 4 Nm.
Clean the chain stay using isopropyl alcohol. Install the Chain Stay Guard by removing adhesive backing and fixing it to the frame. The bottom rearward edge should be 12mm from the front edge of the Rear Derailleur Hanger.
CS026 Stem
The CS026 stem supports internal routing of Di2 wires when used with the Shimano EW-RS910 bar end junction and a compatible handlebar. Refer to component manufacturer's service center or website for details.
The Pass-through fitting stem cap is provided for test fitting. Once stem height is confirmed and fork steerer is cut, replace it with the Aero stem cap and bond-in fork insert. If you wish to keep the fork steerer long, the Pass-through fitting stem cap can be used permanently with spacers on top and a standard top-cap for headset adjustment.
Torque: 5 Nm maximum for stem bolts. Compatible with Bar Fly Direct MINI and MAX stem mounts.
AB06 Handlebar
The AB06 handlebar supports internal routing of Di2 wires with the Shimano EW-RS910 bar end junction and a compatible stem. These routing illustrations supplement manufacturer instructions; refer to component manufacturer's service center or website for details.
Dimensions: 128mm Drop, 80mm Reach. Di2 Cable Exit. Di2 Cable to Junction B. EW-JC200 Connector. EW-RS910 Junction A. Di2 Cable to Rear Shifter. Brake and mechanical shifter housing are routed externally in pockets on the underside of the bar.
Tire Clearance
The Cervélo bicycle complies with ISO 4210-2:4.10.2 for tire clearance. To meet safety standards and maintain your Limited Lifetime Warranty, a minimum of 4mm clearance must exist between the tire and any frame element. Due to increasing tire and rim complexity, Cervélo recommends checking available space before selecting a tire.
Measurement Steps:
- Measure space between chainstays at the bottom-bracket junction.
- Measure space between seatstays at the top of the tire.
- Using the smallest of these two measurements, subtract 8mm (4mm per side) to determine remaining space.
- With the tire installed and fully inflated, measure tire width to ensure it fits.
Warning: Failure to follow these guidelines may result in frame damage not covered by Cervélo Limited Lifetime Warranty.
