Wolf Tooth fit question need help

hi,

I have done this before with 6800 ultegra Di2, I have used the (V1 )road link and was able to fit a SRAM 11-42 with room to spare and to answer your question.

  1. you need option 1: the Direct Mount (DM) version, you can replace the existing link on your rear derailleur with this, this will drop it by a few cm. adjust the b screw.

  2. you will need a new chain to account for the bigger 40 tooth cog, allow some fudge factor if you happen to cross chain (big, Big), unless you have set up synchro shift.
