GENERAL INFORMATION
Damage can lead to failure of the components and thus to serious
injury or even death. Externally damaged or defective components
must not be used under any circumstances and must be replaced
immediately. If you are unsure, contact us or your dealer.
WEIGHT LIMIT
The Flat Bar 2.0 is not subject to any weight restriction.
SHORTEN CARBON HANDLEBARS
The Flat Bar 2.0 may be professionally shortened, but only to a width
that the brake levers can be mounted on the provided clamping
area. For this purpose wrap the affected areas with crepe tape.
Shorten carbon handlebars only with a fine-toothed carbon blade
or a Dremel. The use of a metal pipe cutter is not permitted. After
trimming, the crepe tape can be removed and, if necessary, the
ends deburred with fine sandpaper.
APPEARANCE
Our components are 100% handmade. Thereby it can come to
different appearances. It makes each component unique and has no
influence on the safety. By direct incidence of light you get a great
view of the individual fibers with partly shimmering shades.
INSTALLATION
INSTALLATION COMPATIBILITY
You can use your Flat Bar 2.0 with all conventional stems. The
diameter of the clamping area of the stem should be 31.8mm
(±0.15mm). The width of the handlebar clamping of the stem must
not exceed 60mm.
Make sure that the handlebar clamp of the stem as well as the brake
and shift levers have no sharp edges. We do not recommend to use
them. If you still intend to do so, please remove burrs from all sharp
edges in the clamping area of the handlebars carefully with a file
and abrasive and round them off. Please note that this measure
may void the manufacturer‘s warranty. Contact the manufacturer
if necessary.
INSTALLATION ON THE STEM
• Use the supplied carbon assembly paste for mounting the
stem to reduce the necessary tightening torque, thus relieving
the material. To do this, apply the assembly paste to the
clamping areas.
• The handlebars may only be mounted with grease-free screws.
• Position the handlebar in the center and do not tighten the
stem bolts to the maximum torque immediately, instead
tighten them gradually and alternately.
• Be sure to observe the maximum tightening torque of 5Nm.
When mounting the stem indentations in the handlebar can occur
depending on the design, mounting and tightening torques. This is
quite normal. If you are unsure about the safety, you can contact us.
INSTALLATION OF BRAKE AND SHIFT LEVERS
• Use the supplied carbon assembly paste for mounting the
stem to reduce the necessary tightening torque, thus relieving
the material. To do this, apply the assembly paste to the
clamping areas.
Attention: Distinction between unfavorable and favorable
clamp designs.
When mounting the brake and shift levers, a distinction
must be made between unfavorable and favorable
clamping designs. An overview of critical features of
unfavorable clamping designs can be found on the
next page. Please check very carefully whether your
components fall under this category. If you are unsure,
please feel free to contact us.
• If you intend to use brake and shift fittings with an unfavorable
clamping design, the tightening torque should be a maximum
of 3 Nm.
• If you intend to use brake and shift fittings with a favorable
clamping design, the tightening torque can be increased to a
maximum of 6 Nm.

ATTENTION:
COMPONENT MOUNTING ON CARBON
HANDLEBARS
Some new brakes and shifts on the market have a very
unfavorable clamp design for carbon and lightweight
handlebars. The clamps are not round and the contact
surface is minimal. Loads are thus no longer distributed
evenly over the clamping area of the handlebars, instead
they lead in locally. In addition, the maximum Nm values
specified by the component manufacturers usually refer to
aluminum handlebars.
Due to this development our MTB handlebars have received
an upgrade. We use a special polyester prepreg mesh as
a top layer for the clamping area for the brake and shift
fittings. It has a high strength and creep resistance and at
the same time has a low sliding friction and sliding wear.
We use it exclusively in the clamping areas. Thus, punctual
loads are absorbed much better and distributed evenly over
the handlebars. Impressions of the clamps are reduced to a
minimum and the carbon layers underneath are protected.
Please read the following section carefully and follow the
instructions.

ATTENTION: TIGHTENING TORQUES
In general, the fittings should only be tightened that they
can just no longer be twisted. For this reason, the specified
maximum tightening torques should usually not have to be
used!
