Fitting your Idylle RaRe FCV onto your bike requires care and attention. For your safety, please follow these instructions. 

1.1 The steer tube 

 

Before cutting the steer tube, first take some measurements: height of the headset, length of the  frame’s head tube, height of 
the stem and then add 5 to 10mm. 
 
 
Calculate the length as below: 
Length of the head tube of the frame + height of the h height of the stem + 5 to 10mm. 

 

 

 

 

1.2

 

Adjusting stanchion position in the crowns 

Depending on the bicycle, the position of the fork in the crowns can vary slightly. However, you must maintain the following 
measurements to ensure the fork’s function and your security.  

The  lower  crown  height  ensures  the  full  use  of  fork  travel  and  tire 
clearance.  Use  the  following  measurements  to  set  your  lower  crown 
height. This height is measured from the top of the fork leg (the bottom of 
the visible part of the dust seal) to the bottom of the lower crown. 
 
27.5’’-wheel model forks: 217mm 

 
CAUTION 
This measurement match with a maximum of 705mm tire diameter. 

 
The  distance  between  the  top  of  the  upper  crown  and  the  top  of  the 
stanchion must be between 0mm and 30mm (B). 
 
Once  you  have  assembled  the  crowns  and  adjusted  the  heights  to  the 
measurements  above,  you  may  proceed  to  the  tightening  the  bolts.  USE 
THE FOLLOWING BOLT TORQUES. 
 

All crown bolts must be torqued to: 4 - 5 n.m (35 to 44 in-lbs.) 

 

 

 

 

 

 

 

 

 

 

1. Assembly 

 

Caution:  

Never attempt to remove or replace the steer tube independently from the lower crown. Modification of the integrated 
cown-steerer can cause catastrophic assembly failure. 

 

    217mm 

Caution:  

For  Idylle  RaRe  FCV  forks,  do  not  clamp  the  crowns  past  the 
stanchion cutouts. This will result in damage to your fork.
