1.3 . The front wheel
To assemble the front wheel, check the following instructions :
1. Undo the 4 bolts at the bottom of the legs of your forks.
2. Put the front wheel in-between the legs.
3. Put a small amount of grease on the thread of the axle of the front wheel.
4. Put the axle in and tighten, no need to over tighten it, stop when you start feeling resistance.
Tighten first the 2 bolts on caliper side and then the 2 bolts on the other side,
to the same tightening torque : 2 to 3 nm.
1.4. Installation of the braking system.
Please refer to the manuals of the manufacturers. Meanwhile, apply the folowing instructions :
Minimul lenght of thread of the caliper screws into the fork : 10 mm
Tightening torque : 9 to 10 Nm
2.1. Spring
Before giving your forks their first spin, please do check that you are using the right spring rate.
With your forks (providing that it is not an original equipment) come extra springs in order to adjust to most of the
riders. By default, your forks come with the orange spring within.
The table below is for own use, please refer to it.

Spring Preload
The sag on your forks shouldn’t exceed 30 to 50 mm (15% to 25% of the travel) therefore it is very important not to
preload the forks more than what‘s necessary. The sag has to be considered in dynamic situations (going down the
hill for instance) not static situations before preloading the spring, and it allows to raise the chassis at its right height.
Use a 14mm spanner to preload the spring (left stanchion, disc brake side) turning clockwise.
Do not preload further than 20 clicks. Otherwise, it’s better to change for a softer -or harder- spring.
Spring swap
It’s an easy operation.
1. Undo the bolt on the left hand side of the upper crown. Undo the top cap on the top of the stanchion.
2. Take the spacers and the preload rod that seat on top op the spring.
3. Push down the forks and take the spring out of the stanchion.
4. Replace the spring, the preload rod and the spacers back and screw the top cap back on the stanchion.
