MirageDrive Drum Bolts Options:
Note: It is important to make sure the drum bolt is installed reasonably tightly, and this is especially true with drives that use the newer drum bolt, including GTKU and MD180 / MD180 KU drives (pictured above).
Tension the bolt so that the crank is flush against the length adjustment holes so that there is a moderate amount of friction to the fore and aft movement of the cranks. A loose screw could allow the crank to move away from the adjustment holes and possibly strip the outer plastic away between adjustment holes.
