Lower Tendon Connector
The lower tendon connector is the distal attachment point for the ball
end of the tendon.
This connector can slide up or down the pylon, and is used as addition-
al adjustment for the tendons sliding distally to increase tension and
proximally to reduce tension. The lower connector that comes in the kit
is a designed to fit a 30mm pylon and is hinged for easy on and off.
X/CAM™ Guide Wheels
To enhance the fluid dynamic feel of the tendons a three (3) position
tendon X/CAM™ Guide Wheel system is used in conjunction with the
tendons at the knee axis. These X/CAMs™ allow the highest tuning of
tendon response within further progression of knee flexion.
Having a tendon resistance properly tuned within a specific range of
flexion is very important as it means the user can tune specific points
in flexion for the tendon to
CAM
into action, offering additional support
where it’s need it, or X/CAM™ out the energy for explosive returns.
Because of this X/CAM™ action Crossover™ users also achieve
much lower
preflexion resistance
allowing them to conserve much
needed energy while still providing the power and support needed
flexing 25 degrees and beyond.
Each X/CAM™ offers three levels of progression and an additional 4
th
non-pinned option on each side, and can be used with the Crosso-
ver™ tendons in singles or pairs. These selections offer an unsur-
passed series of options within the full range of flexion that can all be
done on-the-fly without tools. The X/CAMs™ can also be utilized in
reverse (4
th
option) or in a non-pinned free movement position deliver-
ing the identical performance of the previous BTK model with a round
guide wheel.
Pos.1 (single dot): This position is suggested for the least amount of X/
CAM™ effect with knee flexion (least amount of resistance).
Pos.2 (two dots): This position is suggested for a mid-range of X/CAM™
effect with knee flexion (middle range of resistance).
Pos.3 (three dots): This position is suggested for a maximum X/CAM™
effect with knee flexion (maximum range of resistance).
Pos.4 (no locking pin): In this position the X/CAM™ is in a FREE motion
state with no increased resistance. This position is suggested if the
amount of flexion tension with the tendon is desired in the very least
amount of tension as the X/CAM™ will not engage during knee flexion.
