Urrun: routing a dropper cable

[markloch]

I won a raffle, and am getting a ‘23 Urrun 30!

No dropper on the ‘23, wondering if anyone has routed a cable through the downtube and whether it requires the battery to be removed or can one feed the housing through. I assume the motor needs to be pulled. I’ve done it before on my Rail but it’s got a removable battery.

You could install a SRAM AXS Reverb wireless dropper and avoid the “cable threading nightmare”.

I’m not familiar with this bike but removing the motor and battery may be necessary. It is on the Trek Rail.

You’d be happy with with the Reverb dropper …I am.

Ah! …okay.

The big disadvantage with the Reverb is the price and a slight weight increase. Otherwise it’s easy to install, good quality, cleans up the cockpit and you can take it off easily for service.

Found the bike’s ”Blue Paper” - I have to hand it to Orbea, they don’t skimp on their documentation. Very thorough with exploded part diagrams, etc. Not clear whether the battery needs to be pulled to wire a dropper.

Elegant if complicated setup: the cables and wiring run through the stem into the head tube, and the electrical wiring for the thumb switch and optional lighting switch are routed through holes in the handlebars.

I had to remove the battery. Then everything was super easy and fast.

Did you remove the battery? With the battery in place, I can get the cable most of the way through, but it hits something and won't go all the way.

I didn’t for the dropper cable, but I did when I was running lighting and pulling the shifter cable (went Di2). It was easy, go for it. From the Blue Paper:

Did you thread the cable housing down the downtube following the RD and rear brake hoseor does it have its own guide? As long as i can get the housing into view at the bottom of the seat tube i can fish out and pull it up.

I didn’t see a guide (and honestly didn’t look for one). I just tried to prevent the lines coming down and on top of the battery from tangling/binding when reinserting the battery.

Im really hoping that i might be able to route the housing w/o dropping the kemens motor & removing the battery. I mean its only one cable and with a bit of massaging i "think" i might be able to get it into the BB shell. One thing i didnt think about was getting around the charging port though or how the charging port ight keep me from using the grabber to grab the housing and pull it up the seat tube. How was it getting the housing beyond the charging post?

It's pretty tight in there, guiding a thin wire through with a magnet is one thing, pulling a thick and stiff cable housing is another. As I wrote above, the first time I dropped (well, flipped bike and lifted) the motor to install the dropper I didn't pull the battery and it was a struggle pulling the housing through the downtime. The second time I pulled the battery too, when I wired lighting to the motor and removed the shifter housing when I switched to Di2 derailleur. I wish I had done so the first time around, it would have made the dropper install a lot easier.
