Events can be dusty, dirty places.
For Eventers, the MDC Intelligent line of stirrup irons are basically pieces of machinery working in a dirty, sometimes wet environment. Once a year or so, a non-greasy spray lubricant should be applied to the rotating top and exposed screw. Wipe clean after application. The interior of the stirrup can be further cleaned by applying the spray lubricant through the two access holes located under the flex mechanism housing.
You should always check your gear regularly, keeping everything clean and free of debris to guarantee proper wear and movement.
If you notice the top screw of your MDC Stirrups getting loose, discontinue using the stirrups! If you purchased your MDC Stirrups through us, contact us and we’ll work with you and the manufacture to fix the problem.
