Risk of accident caused by a malfunctioning stem system due to loose screw connections.
- Check the required tightening torque of all screw connections after the first 100 km
– Retighten the connections if necessary. Repeat this check every 2500km!

If not properly performed, assembly and maintenance work could cause accidents resulting in
death or serious injury.
- Do not overestimate your technical ability. All assembly and maintenance work should be
performed by a specialist workshop for bicycles. This is the only way to ensure the work is
conducted in a professional manner.
WARNING
There is a risk of accident due to sudden unexpected failure of the stem while riding if any
carbon fibers on the stem are damaged during any installation procedure.
- Before starting work, make sure that the steer tube is compatible with the stem.
- Remove sharp edges and burrs and any other contamination / grease from the steer tube before
starting assembly.
- Be particularly attentive to cutting edges of shortened steer tubes and rework the edges if
necessary.
- Never exceed the max. permissible height of the lower spacers. (fig. 1)
- Never exceed the max. permissible overlap of the top spacer or stem. (fig. 1)
- Never exceed the tightening torque of 6N·m under any circumstances when tightening
the top cap adjusting screw. (fig. 2)
- Never exceed the tightening torque of 4N·m when tightening the clamping screws on the stem.
(fig. 3)
There is a risk of accident due to sudden unexpected loss of control while riding if the stem
slips on the fork steerer.
-Never apply any lubricant or grease to the steerer tube.
WARNING
Applying an appropriate carbon assembly paste between
the stem clamping area and steerer tube enables the
required tightening torque to be reduced to achieve the
same clamping force.
