Fitting your Idylle onto your bike demands care and attention.
For your safety, please do respect the following instructions.
1.1 The steerer tube
Before cutting the steerer tube, first you have to take some measurements :
Height of the headset, length of the headtube of the frame, height of the stem and then add 5 to 10mm.
With a standard stem clamped on the steerer tube :
Add the length of the headtube of the frame to the height of the headset and to height of the headset plus 5 to
10mm.
With a stem bolted onto the upper crown :
Add the length of the headtube of the frame to the height of the headset plus 5 to 10mm.
1.2 Stanchions and crowns
Depending on the bike, the position of the stanchions in the crowns may slightly differ. Nevertheless, it is actually
very important to follow all the measurement advices listed below, to ensure a perfect function, and a total security.
1. ASSEMBLY
CAUTION
Never attempt to remove or replace the steerer or upper tubes independently from the crown. Modifying the
integrated crown, steerer, or upper tubes can cause an assembly failure, resulting in a loss of control of the
bicycle and serious injury.
When installing the wheel with a properly inflated tyre, make sure that
the forks achieve minimum tyre clearance. Simply measure the distance
from the top of the leg (lower part of the seal) to the outer of the lower
crown, it has to be between 210mm to 220mm (A).
IMPORTANT
This distance is for tyres of a maximum diameter of 705mm.
The distance between the top of the upper tubes and the top of the upper
crown must be included between 0mm and 30mm.
Once the forks assembled to the measurements listed above you can
then tighten but always refer to the recommended tightening torque.
Tightening torque for all bolts of the upper and lower crown : 4 to 5
