    Both were having the issue of shifting off the largest cog into the spokes

    I connected them to the computer using the Etube software and was able to understand the problem better

    One issue is that to get them into adjustment correctly I have to adjust the micoradjust setting to +12

    Is there a way to reset the gear that Di2 thinks it is in so the micro adjust is closer to zero?

    Should I add a spacer so that the rear derailleur is farther from the dropout so that the micro adjust is closer to zero?

    Finally - I am probably going to purchase a rear derailleur alignment tool. Will this be safe to use on the Cannondale Supersix EVO HiMod frame?

    Thanks in advance!!!

    Did you ever get this figured out? I'm having the same problem with my 2016 Cannondale Evo HM. It just came out of the blue. I tried a new hanger, but still can barely get it to shift with micro all of the way out. Limit screws are fine. I'm also tried 2 different wheels. I might through a 6870 RD on it tomorrow to see if I still have the problem. Wondering if something is up with the 9070 RD.

    See this thread Di2 adjustment issue

    The OP ended up milling a derailleur hanger to allow his Di2 to shift to the largest cog correctly!

    And I posted that the 33 click adjustment range doesn't reset, so I clicked more than 33 in one direction, then back 16 clicks to get to the center of the adjustment range.

    Just to update - I bought a Park rear derailleur hanger tool and tweaked the alignment - the shifting is now just fine

    Thanks!
