Recommended equipment:
For quadriplegics or people with limited finger
function, a
Tetra Clip
is available to operate
the quick-release axle lock. The Tetra Clip is a
plastic housing that is screwed onto the outer
side of the drive wheel hub and operated by
means of a push-through pin. The pin has a
red marking on one side (quick release axle
opened) and a green marking on the other side
(quick release axle locked). The pin can be
pushed using the ball of your hand in the direc-
tion of the middle of the drive wheel and there-
by the quick release axle opened or closed.
