Di2 Front mech slow to move

Hi All,

My Ultegra 6870 FD is becoming very slow to move either way. It completely stopped working yesterday, even though the battery showed charged (the RD also worked). Then I charged it and it came back to life, but the shifting is very slow. Any thoughts? I have been riding it over the winter period here in the UK


  • It's probably dirty and full of salt. You need to give it a good clean at the hinges or it will break

    I had exactly the same problem....really slow moving onto the big ring. I flushed it out with wd40. Works fine now.

    take it off, and woosh it around a bucket of hot soapy water

    spray gt85 in the pivots to blast the water out.

    Refit it

    give it a clean every now and again

    probably best to not put a Di2 mech into a bucket of water!!!
