► TECHNICAL FEATURES
►► CHANNEL Tubeshape Technologie developed by ADP Engineering
Distinctive mark and basis of all ROTWILD frames: the CHAN-
NELTUBE technology developed by ADP ENGINEERING. These
tubing sets, exclusively developed specifically for ROTWILD
mountain bikes, racing bikes and road bikes, are characterised by
tube sections with wall thicknesses based experimentally and
analytically determined values, and individually matched to each
area of use. This individual design allows us to emphasise spe-
cific development aspects in relating to the intended use of the
finished bikes, for instance, to increase the bottom bracket rigidity, the track stability
or to reduce weight wherever it makes sense.
►► Aluminum Alloy AI 7046 T6
Al 7046 T6 is an aluminum alloy with a different formula of basic material contents,
e.g. in comparison with the often used classical Al-Alloy 7020 T6. The improved hot
hardening of the material leads to a significantly higher tensile strength than Al 7020
(around 30 %). In addition, the extremely important expansion limit for a component
becomes much higher (around 40 %) and increases resistance to shock fractures or
breaks. The use of the new Al-Alloy Al 7046 T6, in combination with our proven
CHANNEL Tube Shape Technology, results in super-light frame materials with signifi-
cantly improved mechanical properties and an optimised weight/ durability factor for
ROTWILD bikes. At the limit of production for example: The latest downtube of the
ROTWILD XC Racing Series models – 4 times inside-butted, 2 times outside-butted,
3 different shapes.
►► CFP CHANNELTUBE developed by ADP Engineering
Stiff, light and high durability for a long life cycle: For the new ROTWILD Carbon Fibre
reinforced plastic (CFP) our engineers use a
“ tube to tube” technology where every single
CFP-tube is bounded together with high
dimension accuracy. Each single tube is made
by hand. Shape, thickness and the directions
of the fibre are orientated to the forces within
the construction. At this point we are able to
use CFP technology within a ROTWILD
mainframe for the first time. For a highly
competitive construction with a maximum of
first-class quality.
