Completely disassembled for cleaning and re-greasing. Feel really good about it. I have always done my own minor adjustments but now starting to take a more hands on approach to my bike. Like everything else in this world, there is a real sense of accomplishment and security when doing things yourself. It is really nice to know everything was cleaned and re-greased properly. Going to do my hubs next. My bike is a 2012 so it's been about 4 years since it was built. It is due for an overhaul. For those who are thinking about it or are anxious just go for it and take it slow. Lay everything out as it comes off so you know the order it goes back. YouTube is an invaluable resource.
