Clavicula M³
Maintenance
Before each trip
WARNING
Risk of accident due to material damage or assembly error.
-Check your THM components before each journey to ensure the bonded joints are com-
pletely undamaged. Send us your THM components for inspection before further use if
damage is visible (cracks, fractures, clicking sounds, wobbling, etc.) or if you are in any
doubt about their functionality.
-Check your THM components before each journey to ensure the surfaces are completely
undamaged. Send us your THM components for inspection before further use if damage
is visible (deep scratches in the paintwork which extend into the carbon structure, large
abrasions, etc.), if you are in any doubt about their functionality or if the Clavicula let-
tering is abraded at one or more points (wear indicator).
-Do not exceed the maximum overall weight for which your THM components have
been approved – see Size , page 10.
Checking the bottom bracket clearance
NOTICE
Risk of damage to the bearings.
-Never try to remove the bearing seals from the bottom bracket.
-Your THM bottom bracket is elaborately sealed and provided with permanent lubrica-
tion. There is no need to re-lubricate the bearings!

Grasp both cranks of your bicycle.
 Try to move the cranks to the left and right.

If you feel bearing play, it means that the bottom
bracket is loose and needs to be adjusted immedi-
ately – see
Adjusting the bottom bracket , page 20.
 Now shift the chain onto the smallest chainwheel.
 Remove the chain from the chain ring and place it
onto the bottom bracket housing.

The bottom bracket can now be rotated freely.
 Use two fingers to grasp one of the cranks directly
by the bottom bracket axle and rotate the axle in its
bearing.

If the bottom bracket axle rotates with perceptible
resistance, it means that the bottom bracket is too
tight and must be adjusted immediately –
see Adjusting the bottom bracket , page 20.
