1. Apply grease to the bearing seats, and Install the upper & lower
headset bearings into the head tube.
2. Fit the fork into the head tube with the complete headset,
required spacers, and the stem.
3. Apply the minimum pressure needed to ensure the assembly is
fully seated. Mark the steerer tube at the top of the stem.
4. Remove fork and clearly mark the fork steerer tube at a
point 4mm below the rst mark. Take care to verify that this
measurement is correct as this denes the cut line for the
steerer tube.
Avoid breathing the dust created during cutting carbon
composite materials.
Do not exceed 50 mm maximum total spacer height,
including the bearing cap.

5. To trim fork steerer, use only a saw suitable for cutting carbon,
and a cutting guide.
6. Carefully sand a bevel to the inside of the cut end of the steerer
tube to t the insert.
7. Dry t insert to check that it is ush with the cut end of the
steerer tube.
8. Use isopropyl alcohol to clean the inside of the steerer tube
and the outside of the insert.
9. Fully mix the two-part epoxy and apply to the outer surface of
the insert with the wooden mixing stick.
10. Slide the insert into the steerer while rotating it slowly until the
ared end sits ush with the top of the steerer.
11.Wipe away any excess glue from the outside surface of the
steerer tube with the isopropyl alcohol wipe.
12. Set the fork aside and allow it to sit undisturbed for the full
curing period.
Do not attempt to t the fork into a bike prior to the completion
of the full curing period.
Improper cutting of the steerer tube could cause a failure that
results in severe injury or death.
Insert should be ush
with cut end of the
fork steerer tube

SMALL PARTS
Designed to accommodate electronic, mechanical and hydraulic controls, the C Series frames are
engineered to provide seamless integration of all shifting systems, regardless of method or brand. In
order to do so, you will require the parts shown below:

6
Install chain catcher when installing the front
derailleur. Complete nal adjustment with the
chain in the small chainring and largest cassette
cog.Tighten the connecting bolt to 4 Nm.

using the bolt provided
with the derailleur.
Torque to the derailleur
specications.
FRAME PREPARATION
Lightly grease Rear Derailleur Hanger Fixing
Nut and install Rear Derailleur Hanger, nger
tight. Final tightening will be done after rear
wheel installation.
Do not nal tighten rear derailleur hanger assembly
without rear wheel installed. Doing so will result in a
misaligned derailleur and poor shifting.

BRAKE HOUSING INSTALLATION
It is recommended that the hydraulic brake hoses or brake cable housing is installed rst. These routing
illustrations are intended as a supplement to the manufacturer’s installation instructions only. For both
hydraulic and mechanical disc brakes, please refer to the component manufacturer’s service center
or website for further information.

Route hydraulic brake hose or mechanical brake
housing through the frame and fork using the Disc
Hose Bushings. Install and adjust calipers as per
manufacturer’s instructions.
NOTE:The brake line
entry hole on the C3 and
C2 is on the fork's front
surface.

With the brake hose
already in place, install two
piece DownTube Cable
Stop (Mechanical) and
route cable housing (with
ferrules) into stop, until the
housing rests securely in
the pockets.
MECHANICAL CABLE ROUTING
It is recommended that front and rear derailleur cables be installed after the brake hose has been installed.
These routing illustrations are intended as a supplement to the manufacturer’s installation instructions
only. Please refer to the component manufacturer’s service center or website for further information.

10
Route gear cables out of the bottom
bracket cable port. Ensure that the
cables are not twisted together.
The front cable travels across the non-drive side slot, and in
the direction of the seat tube. The rear cable travels along the
drive side slot, and along the chain stay. When complete, snap
Bottom Bracket Cable Guide into place.
Install Rear Derailleur Press-In Cable Stop.
As per manufacturer’s instructions, install rear derailleur on rear
derailleur hanger, cut appropriate housing length, and attach cable.

11
With the brake hose already
in place, route the down
tube electric wire to the
bottom bracket. Install the
two piece DownTube Cable
Stop (Electric).
ELECTRIC CABLE ROUTING
