Shim adjustment:
Step 1: Lateral positioning of the hold: centre the shim as much as possible under the boot
(mounting holes in the sole in the middle of the shim windows).
Step 2: Longitudinal positioning of the shim (forward or backward under the shoe). The
majority of experts believe that the mark on the shim (3) (which shows the axle of the pedal)
must be located under the centre line of the internal metatarsal joint: See diagram opposite
The centre line of the joint of your internal metatarsal is at the centre of the articulation
between the foot and the big toe.
Step 3: Once the shim is positioned as described above, place the washers and tighten the
screws without forgetting to grease their threads. The tightening is done with a 3mm Allen
key or a flat screwdriver. The tightening torque must be between 5.5 and 6 Nm.
Step 4: Snap your foot into the pedal and do a few meters with your bike. If your heels touch
the bases or if you feel that you are pushing your ankle or knee more than one side, change
the orientation of the shoe. Repeat until you feel no discomfort during pedalling.
