So I finally was able to take my new Di2 setup outside now that winter is finally over up here (I'm in Canada) and I couldn't be happier on how smooth things work.
- BUT -
I noticed that when I'm in the big chain ring up front, there is some noise coming from the rear derailleur at the back (from mostly all cogs) but when i switch to the smaller chainring, its smooth as butter back there, and not a single peep from the RDR.
I've tried to adjust it before, but made a mess of it - mostly because I don't know what is causing it and what the action to fix it is. So I need to understand what is causing the noise, and how you go about and fix such issues.
Anyone willing to explain, i'd be forever grateful :)
