This is the new carbon rear stay that goes back to the concepts of the Muscle
line. The chain stay was built with the "single plug" concept that confers the
stay with considerable resistance to torsion.
The two carbon elements are
made by laying layers of T700 and HM carbon fibre and then coating them with a
special material called Nickel Braid. Columbus Carbon Fibre Lab has used Nickel
Braid to achieve considerable improvements in the stay's response to external
vibrations.
The main characteristic of this material is that it reacts to
deformations by hardening, creating an effect of softening vibrations in
proportion to their intensity. The tubular shape of the Nickel Braid creates an
uninterrupted structure that increases the reliability of the components and
their durability over time. The bottom bracket is made from one piece and CNC
machined, the connection with the monocoque the chain stay is lowered
(off-centered) respect the center of the bottom bracket, increasing the
stiffness of the rear triangle of the frame. The comfort of the Super Muscle
stay is provided by the special shape of the casings that resemble human
muscles. The dropouts are also made from one piece and CNC-processed, have the
pivot of the connector on the seat stays, positioned in line with the centre of
the wheel hub. This makes it possible to adjust the rear stay for all frame
measurements, with minimal adjustments to the carbon elements.
