4-Carbon Frame
The manufacturing process of the carbon parts
often leaves micro-burrs and sharp edges. We
recommend de-burring the edges to minimize the
risks of electrical wire cuts, etc.
This is particularly
important in the areas shown in red.

Note:
Tighten the three screw M2.5.
After tightening, check the
axial play of the main shaft. It
is possible to reduce any axial
play by adding shims.
IMPORTANT:
Very carefully
check to make sure you can
turn the main shaft freely.
If you feel too much friction,
you have used too many
shims, you can remove a shim
until the shaft turns freely.
