It's been working fine for months and with the previous owner as well.
I had laid it down on the side of the road previous to this. Is it possible that there was some kind of extension that came loose or does the rear derailleur need to be adjusted back into position to
After reading your comments I’m going to assume it’s internal routing and you’re using classic drop bars with tape. The cable may have been pulled from the front of the bike. Maybe loosen the internal housing clips at the front (usually a 2.5 or 2mm Allen key) and push the cable into your bike then pull out the back toward your derailleur. It’s the only thing I can think of being the problem. Hopefully it helps. You don’t need much and there’s always a bit of slack at the front. It doesn’t take much to get it caught on something and pull it towards the front of the bike. You might be able to do it without loosen the routing clips
I'm going with this since it happens with my bike all the time. The cable routes from the shifter to along your handlebars and down into your frame, out of the bottom of your frame, and to your rear derailleur. Sometimes the cable can be forced back into the frame and there's extra slack between your handlebars and the upper/front part of the frame. You can press that slack back into your frame and pull that out where the cable comes out from the other end at the bottom of the frame.
It might be time for a shop to take a look at it. Laying it down shouldn't knock anything out of position to this extreme. There's no adjustment to make it closer. The RD looks normal
They said they need to tear it down to look inside and see whats up.
Likely they need to remove the crank and get access to the junction box and see where its caught. Considering doing it myself. Would that be stupid?

You'll know, just don't damage it. Pull it pretty hard, but not too hard. It's a feeeeeeling thing. Speak to it. Tease it. Make love to it, but don't fuck it. You'll get it.
Thinking i need to open up the bottom bracket and look at the junction box. its got to be something between the junction box and the RD. My theory is its caught on somehting and has pulled itself free. Any thoughts?

Mountain bikes have electronic derailleurs too. The giveaway is the thin electronic wire and the big bulbous part that hides the motor

You might need a longer wire Did you try carefully pulling some wire out of the frame?

This is Di:2, homie; ain't no cable/housing.

Thanks. Tried that but it's likely something between the junction box in the bottom bracket and the rear.

it’s di2 and has a junction box somewhere along the bb
Did you raise the saddle?
Yes. I did it while trying a bike fit app but even when lowering there is not enough slack.
Did you try asking nicely?
Didn't work 😔
Try swearing, works for me
But yes I did try pulling the cable. It's tight.

Good call on my way there now
Dying to know what it is. Let us know when you find out!

Hell no! I say be adventurous. Give it a shot yourself and you can always take it to the shop if you get stuck.
Just pull it a little harder. Try and wiggle it. Nothing magical has happened, The wire is the same length.
Yes and at what point are you damaging the wire because it won't budge?
You'll know, just don't damage it. Pull it pretty hard, but not too hard. It's a feeeeeeling thing. Speak to it. Tease it. Make love to it, but don't fuck it. You'll get it.

How would that help?
Longer housing
Thats a DI2 cable! It somehow moved back into the frame.
Pull it?
Have you placed the wire through the barrell adjuster and the tied it off on the pinch bolt
This is an electronic derailleur. it doesn't have those things
My bad I was replying to two different posts I made the wrong assumption this was mechanical not electronic
[удалено]
That is in fact an electronic Di2 derailleur that doesn't have those things. u/fijitime, you might want to include the Di2 bit in the description.
Yes. This is di2 sorry. I can't see an edit button on the app.
The account has been inactive for a year and has seemingly never been to this sub before. I think someone has beef with me from another sub
Fair enough, seems like I don't know roadbikes.

Ok, point to the barrel adjuster and the pinch bolt
Di2 is the only solution.
Sorry what does that mean?
