Torque Arm Installation:
Once the torque plate is installed, the torque arm should be installed into the
neutral position as shown in the photo below. The system is meant to be installed
such that the wire exit passes through the dropout slot on the bicycle frame,
following the arrow in the diagram below.
If your frame has either a different angle on the dropouts, for example a horizontal
dropout, you would need to remove the torque arm from the torque plate and
rotate it such that the wire exit matches the angle of the dropout when the torque
arm is rotated to meet the frame’s chain stay. The splined interface allows for
rotation between the torque arm and torque plate in 30 degree steps.
Once the arm orientation is set to then it can be screwed tightly in place with
either 5 or 6 of the countersunk M4 Fasteners using a T20 Torx Driver.
