Ahead-stem angle adjustment
Thank you for deciding to buy your new stem from our company.
Compare the SAFETY LEVEL on the stem with the attached table
in order to check whether it is suitable for the intended use.
Before use please read the following assembly and safety
instructions carefully. Keep them in a safe place and pass
them on to the next owner if necessary.
Assembly
Basic technical knowledge is required for the assembly of this product. If you do
not have this knowledge, please use the services of a specialist bicycle dealer.
Check that the internal diameter of the Ahead stem clamp (28.6 mm) fits the
external diameter of the steer tube. There are 2 different sizes:
with 1" steer tube: external diameter 25.4 mm and
with 1 1/8" steer tube: external diameter 28.6 mm.
The internal diameter of the stem clamp must fit the external diameter of the
steer tube.
Now place the stem on the steer tube and adjust it so that it is aligned with
the front wheel.
For safety reasons the steer tube can be max. 2 mm shorter
than the stem clamp.
c
Now tighten the tube clamping screws evenly to the tightness values
indicated there. If no tightness value is specified the following values apply:
M5 – 6-8 Nm / M6 – 10-12 Nm / M7 – 15-17 Nm.
Before assembly check that the handlebars and the stem are compatible.
Also check that the difference in diameter between the clamping area
d
of the handlebars and the handlebar clamping section is no greater
than +0.2 mm.
For safety reasons you should not combine the stem with
carbon handlebars – risk of breakage!
Make sure that the clamping areas are clean and
free from grease!
To adjust the angle of the stem you release the angle clamp screw
with the appropriate hexagonal key.

Safety instructions

The tightness of the bolts must be checked after approx. 500 km and once more
during the regular service intervals (with once a year as a minimum).
This stem is not suitable for mountain biking or competitions.
The heavy demands could lead to breakage.
Do not attach any additional equipment such as a child's seat or
luggage rack to the stem. This could lead to excessive strain on the
stem and cause breakage.
To prevent the risk of a fall or accident, the stem must always
be replaced if it has been damaged.
