Does Shimano suggest bluetooth module (Di2) be installed externally?
Moderator: robbosmans
My mechanic installed the bluetooth module outside my aero bar. He told me Shimano recommends external install to avoid signal interference. Can anyone confirm this? BTW my other two bikes have the BT module installed internally with no issues.

generally, yes. they give you clips to mount alongside brake cable housing. works internally with carbon frames. not much so with titanium or steel frames (weak BT signal).

They recommend that, but it also ruins the look of the "all internal" thing they're trying to achieve. I've done multiple builds with a very short e-tube from the seatpost battery to the wireles unit, and one from the unit to the internal junction without any issues. I also haven't found it to rattle in this position.
On my carbon bikes, I've run mine inside the top tube with no issues. I didn't even try it on my Ti bike. I don't really need Dfly while I'm riding much, so on the rare chance I need bluetooth, I'll just plug in the WU inline on the RD until the update is done, then remove it again.
Honestly though, I've had enough weird issues with the bluetooth software on my IPad that I don't even bother with it any more.

You make a valid point. I was so excited to get it when it came out, but the eTube app is just garbage. So slow and unintuitive. It's still loaded internally, and I had initially thought about including it on my new build, but I'm not of the mind that I'll exclude it. The only real advantage seems to be for Mac users and if one's traveling.Finx wrote: ↑Mon Aug 27, 2018 5:35 pmOn my carbon bikes, I've run mine inside the top tube with no issues.
