3. ASSEMBLY
WARNING: Improper fork installation could cause a failure that results in severe injury or death.
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 (inner or external). 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 inner steerer into the head tube.
3. Slide the compression ring onto the inner 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 (inner and external). Do not use grease on the fork steerers. The use of Tacx Carbon Assembly Compound™ or
equivalent friction paste is recommended to help secure the stem. This increases friction thus allowing for the tightening torque to be lower.
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.
WARNING: To avoid damaging the fork, never try to align the stem without first fully loosening the stem's steerer clamp bolts.
7. Tighten the greased stem bolt(s) to the steerer using a torque wrench. Tighten the bolts to a maximum of 5 Nm
WARNING: 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 lose control and fall. In case of a
disagreement or a conflict between any literatures 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.
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.
9. For brake installation, please follow the instructions as provided by the brake manufacturer, and also refer to this P5X Owner's Manual.
