What to bear in mind with BERGAMONT bikes with carbon steerer
Always make sure before assembly to use a headset compatible with the stem.
If you want to use a product other than the original product, make sure it is
compatible with the BERGAMONT fork. BERGAMONT assumes no responsibili-
ty for problems resulting from the use of products other than series products.
Never use more than 40 mm stack height of spacers between headset and stem
(d). Never use more than 5 mm stack height of spacers above the stem between
the stem and the top cap of the headset (d). Do use minimum 5 mm stack
height of spacers below the stem between the cap of the headset and the stem.
1. The fork steerer, especially in case of a carbon steerer, must be assembled
with the originally supplied internal expander wedge. Never use a standard
star flanged nut on carbon fork steerers (e).
2. When cutting the steerer tube use handtools only. Do not use a power saw or
a speed cutter, but use a hand saw with a fine blade for metal cutting (f) and
a saw guide.
3. Once the steerer tube is cut to the desired length, be sure to remove all burrs
at the top of the steerer tube. Make sure to wear appropriate safety protec-
tion, safety goggles, gloves and breathing mask. Avoid inhaling the carbon
dust. Do not blow or sweep the dust off, but remove it with a moist rag. Dis-
pose of it immediately.
4. Apply a thin and even layer of grease on the bearings before mounting the
fork in the frame. Make sure the clamping surfaces of the stem remain clear
of grease. Otherwise there is the risk that a secure clamping of the stem is
no longer possible. Apply special carbon assembly paste on the inside of
the stem as well as on the fork steerer inside and outside in the area of the
clamping. This increases the friction and ensures a secure fit.
5. Slide the expander into the carbon steerer until it is flush with the top of the
steerer.
Check after the adjustment or assembly, whether the handlebars are firmly seat-
ed in the stem by trying to rotate the handlebars downwards (a). Verify whether
the handlebar/stem-combination can be turned relative to the fork. Do this by
taking the front wheel between your knees and trying to twist the handlebars. If
there is movement, carefully tighten the bolts a little more and check again the
proper fit (b).
Tighten carefully by approaching the prescribed maximum torque value in small
steps (0.5 Nm increments) and check in between the proper fit of the compo-
nent. Never exceed the maximum torque value indicated by BERGAMONT!
Ask your BERGAMONT dealer to explain you both function and adjustment of
your stem or, still better, let him do that work.
DANGER!
G
In the case of turned stems, it is possible that the cables are too short. In
this case riding can be unsafe. If in doubt, ask your BERGAMONT dealer.
DANGER!
G
When removing spacers (c) the fork steerer tube must be shortened.
This change is irreversible. The shortening should be carried out by your
BERGAMONT dealer, but only after you have found your preferred position.
NOTE!
i
If you want your handlebars at a higher position, you may opt for a riser
bar model which has an upward bend. If in doubt, ask your BERGAMONT
dealer.
