I just took delivery of my Compass Duo, and am having problems getting the MirageDrive (MD) to latch properly.
The cassette installs easily and latches in place properly, in both the front and rear drive wells. So, the latches are functional.
When I insert an MD into the well, if often doesn’t latch, even when I make sure everything is lined up properly. Sometimes the MD installs properly in the front well, but it often only latches on one side and I have to push the pedal cranks to the side to get the other side to latch.
I have never been able to properly install a drive in the rear well. The MD180 is particularly bad and I can rarely get it to latch on even one side. If I do get it to latch on one side, I can’t force it towards the other side to get it to latch.
I believe that the front and rear tabs of the MD are bottoming out before the drive seats itself and latches completely. So, the question is how to fix it properly. I suppose I could carve off a bit of plastic to get it to seat lower, but I don’t like the idea of taking material away. Another fix might be to loosen the screws holding the latch mechanism in place and sliding a shim underneath. Hopefully, the nut on the other end of those screws doesn’t fall away.
So, I’m hoping that knowledgeable people tell me the correct procedure for this adjustment.

Good question, mine does the same thing. I have to manually flip the lock to set. I have had some success after spraying the mechanism with a silicon lube but the tolerance is just a bit too tight. I might try a shim (thin stainless washer) under one side to see if that helps. I’d rather have it too tight than too loose though…
