i recently purchased a mavic ellipse wheel set.

i know that this has been addressed in the past, but can not seem to find a straight up answer. i have read that plenty of people have stripped their rear hub by using the wrong parts, and would like to do everything possible to avoid this.

so my questions are simple.

1. will using the provided mavic lockring prevent this problem?
2. will a dura ace cog work properly and not cause this problem?
3. will a dura ace cog + mavic lockring work well together and not create this problem? or do i need to invest in a different brand of cog.

thank you in advance.
