Fork Installation - Cervélo P5X Manuel

FORK INSTALLATION

1. Check the stem, and headset components to make sure there are no sharp or rough edges on any of
the surfaces which could cut or damage the steerer tube. If any rough edges are detected, have the
components repaired (sharp edges removed) or replaced before proceeding.
2. Press the upper and lower headset bearings into the frame, and insert the fork into the head tube.
3. Slide the compression ring onto the steerer, and down until it fully seats in the top of the upper
headset bearing. The split in the compression ring must be oriented toward to left or right side of the
steerer – never towards the front or back.
4. Slide the stem onto the fork steerer oriented as shown. Note the stem must engage both the fork
steerer and the external steerer. Do not use grease on the fork steerer. The use of Tacx Carbon
Assembly Compound™ or equivalent friction paste is recommended to help secure the stem.
5. Lightly grease the threads of the stem top cap bolt, and the stem clamp bolts.
6. Place the stem cap on top of the stem and insert the greased bolt through the cap to engage with
the star nut. Tighten the bolt only enough to remove all play from the headset, and ensure that the
fork still rotates freely.
7. Tighten the greased stem bolt(s) to the steerer using a torque wrench. Tighten the bolts to a
maximum of 5 Nm.*
8. As a final check ensure that the fork rotates freely in the head tube without any play or binding. If
any problem is detected, loosen the bolts and perform steps 6) to 7) again.
Do not exceed the maximum torque specification for the stem. Correct tightening force on
fasteners – nuts, bolts, screws – on your bicycle is very important. Too little force, and the
fastener may not hold securely. Too much force, and the fastener can strip threads, stretch,
deform or break. Either way, incorrect tightening force can result in component failure, which can
cause you to loose control and fall. In case of a disagreement or a conflict between any literature
on recommended torque values, always use the recommended torque specification as printed
on the component or recommended by the component manufacturer over any recommendation
listed in this manual.
