Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Minor update. I saw the cyclist with external Di2 again today and got a chance to ask how it was done so cleanly.

It turns out she had the battery in the seatpost. Wires from shifters run under down tube, junction box under BB with wires running inside seat tube up to battery, then wires run to FD and RD under chainstay.

I don’t know if my bike’s BB shell is large enough to duplicate this setup, but it does look very clean and did not require any holes to be drilled (I think the hole for attaching under BB cable guides gives access to ST).

Hmm....

Doesn't the junction box get mounted using the hole from the obsolescent cable guide?

Or do you have two holes in your BB shell?

Regarding the room inside the BB shell, if you're running an external cup BB and a 24mm spindle crank you'll have more room to work with than running a cartridge bearing square taper BB. I probably wouldn't consider it with the latter.

I did not get to dissect the under the BB items, but best I could tell the wire to the battery went in through the same hole the junction box was attached to. I imagine enough room for both? I know the shop that did her setup (Shirk’s, possibly the best bike shop in the state) so I imagine I could ask them. At this point I am just thinking. But it is tempting...
