• had my new bike delivered but think the Di2 RD is fucked. was fine for 20 mins into a ride and now it won't shift up the block any further than 3rd cog..... and within those 3 cogs it is sluggish and not indexed correctly. No idea how this has happened. FD is absolutely fine. Vid below - any thoughts?

    cant use e tube as I have a mac and my windows computer is locked down by my IT dept and bluetooth module not installed as standard (fuck you shimano/my IT dept)

    also any good "Di2 for dummies" guides? i need to learn more about it rather than just relying on it working - cant have shit like this happening if I am on a group ride. i read about crash recovery mode but I assume there are other things that I need to understand

    lol there is literally a Di2 for dummies guide here - https://bettershifting.com/di2-for-dummies-beginners-guide-to-di2-manual/

  • Crash mode doesn't change any gears. This seems to be changing some.

    Is the derailler hanger straight?

    Is the RD installed so that the B-screw is correctly on the little hanger tab?
