• Has anyone fitted di2 with the battery in steerer tube? I can see it should be possible, the battery bung seems available but do I also need a different expander plug so the wire can go in?

    Can't work out whether this is all worthwhile...

  • Thought about it. Dismissed it as being just a bit too fiddly and requires special bits so not great if something fails and then you have to drill out a steerer bung/top cap somewhere.
