I have 17k and still good, but never had one last this long. Do you swap out the rubber cushion when changing chain and sprockets?

That said at 14k mine is worn down enough to where the carrier will fall out. I ordered a new Cush rubbers for next time my wheel is off. Cheap enough

My stock rear sprocket at just over 20k,

At about 18k it was looking worn but not horrible, but then I did 2500 miles in about a week and a half and did no chain maintenance during that time.

The morning before I changed it, on the way to work, a buddy (in a corvette) and I were playing at 120+ mph for about 30 miles. Pretty sure that's why I lost some of those teeth...the 56 mile commute home that day was a bit nerve racking.
