It has come to our attention that the shifting procedure of the MirageDrive® 180 can be misunderstood by some users.
MirageDrive 180 directional shifting requires that the fins be free to rotate. Rotation can be hindered by contact with the well, hull bottom or obstructions. The following is a reference for properly shifting the MirageDrive 180 in either direction.
Fins under the kayak should be away from the hull during any shift of direction. As a reference to proper fin position underwater… users should shift while their feet on the pedals are closer together – feet on the pedals when spread far apart (fore and aft) means the fins are closer to the hull and that may prevent the fins from rotating freely.
Pedal positions between a 1/4 to 3/4 of a stroke places the fins clear of the hull. Pull the shifter at a slow steady pace.
Pedaling between 1/4 to 3/4 of a full stroke and at a slow short-stroke pace will assist the fin rotation. Shifting while moving through the water rapidly and not pedaling may cause rotation resistance issues.
If the fins are obstructed, pulling hard on the shifter tendons could fatigue them. This can happen if the user is not allowing the fins to rotate smoothly. Pull the shifter slowly.
If a tendon were to fail, this does not disable the drive or the shift function. Users can still pedal the drive, but would have to reach further forward to shift using the lever directly. Users can create a short extension via string or wire if desired until a replacement tendon can be installed.
