Finally got chain and sprockets replaced on 4th gen

Went with this one, as it seemed to be the popular choice.

Unfortunately, i forgot my camera when I installed as I wanted to document the process, however the installation was very easy and straight forward. Total time spent was about 2 hours, however I took my time, as I was not familiar with some of the parts I was pulling off the bike.

I don't notice any difference with the new chain on, however not really sure I am supposed to.

So for what its worth, if you have the right tools, a very simple job.
