2.2. Coil spring (IDYLLE) To get the best performance from your Idylle fork, it is necessary to set and occasionally preload the spring rate. By default, your forks come with the orange spring within. Two extra springs (green and grey) come in the box in order to adjust to most of the riders. See the Idylle coil spring setting table below for reference. You may need to install a coil spring having a different spring rate.

3. MAINTENANCE 3.1 Air bleeding Idylle is fitted with a bleeding screw on the top of the right stanchion. Bleeding your forks on regular basis will reduce the pressurising effect that always happens with those forks. We recommend to bleed your fork every 5 rides in racing use or every 10 rides in recreationnal use. All you have to do is to undo the bleeding screw and put them back on, no need to compress the forks. 3.2.
