2.3. HYDRAULIC ADJUSTMENTS

IDYLLE Rare

IDYLLE Rare comes with 3 hydraulics adjustments: low speed compression, high speed compression, and rebound

Tuning tips :

When it comes down to hydraulic setting there is no such thing as a magical formula, many factors have to be taken 
into account (bike balance, spring rate, geometry of the bike…).Having said that you can draw conclusions from 
what follows :
- Excessive diving of the bike upon braking : harden the LS compression.
- Often bottom out: harden the HS compression.
- Feeling harsh on roots or square edges : soften HS compression
- Uncomfortable, arms pain : soften rebound.
- The forks don’t spring back and stay low after succession of bumps : soften rebound.
- Front too high (in dynamic situation) : harden the rebound.

Whenever you are far from the standard settings (factory settings) It’s always better to consider what influences the  
performance of the forks. Proceed step by step, one setting at a time by hardening or softening few click each time.  
If you ever get lost while you are setting up the forks, always go back to its original settings.

The  

low speed compression

  adjustment seats at the bottom of 

the right hand leg using a flat head screwdriver(1-A).

The 

high speed compression

 adjustment seats at the bottom of 

the right hand leg using a 14mm 6 points socket wrench (1-B).

The rebound adjustment is on the top of the right hand tube using 
a flat screwdriver(2).

Always start from fully tighten position, then tighten down counting 
the clicks to adjust your settings.

Tighten (anticlockwise) = close / harden
Undo (clockwise) = open / soften

Low speed compression : 15 clicks from the fully tighten position.
High speed compression: 18 clicks from the fully tighten position. 
Rebound : 18 clicks from the fully tighten position.

Low speed compression : 10 clicks from the fully tighten position.
High speed compression: 20 clicks from the fully tighten position. 
Rebound : 16 clicks from the fully tighten position.
