Ability to change rear gears lost on my bike. I can pull cable housing out od adjuster on bith sides, please look at the pictures. When i try to push them back in and rotate the adjuster, it seems it doesnt make a difference. My rear gear is currently stuck on lowest? gear (at the smallest chainring on cassete). Is the barrel adjuster broken? I am on the road and i am yrying to get my rear grar working, at least to the bike shop, which is not close. I have tiagra 10 speed.

When I fix a bikes that have seized adjusters, I simply re-do the cable at the derailler, and I am always spot on with perfect shifting, without need to touch an adjuster, working or seized.

In your case, I would get rid of the inline adjuster entirely, and get new housing.

Can't tell if that's broken or not but are you sure your cable hasn't snapped? Could be it's only being held together by a couple strands at the shifter so check near the cable head and along the length of cable.

Have you disconnected the cable at the derailleur? If not, you shouldn't be able to spread the housing at the adjuster like that, and I agree the cable may be broken, probably at the shifter.

The small sprocket in back is high gear, where the rear derailleur (RD) rests with no cable tension. If you need to ride the bike, you may be able to screw the high limit screw (marked "H" on the RD body) all the way in and shift a couple of gears lower to get an easier ride. Don't try to push the RD with the screw--shift into low gear manually while pedaling, then stop pedaling and release the RD. Another method for a lower gear, more complicated, is to knot a broken piece of cable at a frame stop or exposed housing end, manually shift into low, and tighten the RD pinch bolt in that held position.

Update:

yes, the cable was broken, but havent noticed at the time of writing.
I will buy a new cable tomorrow, hopefully I will not need to buy a new housing.

Unless your housing is relatively new, I’d consider replacing it while you’re doing the inner cable. New housing can make a new cable even smoother, and it only costs $1.50 a foot or so…

Yes, but threading it through my bike frame is a nightmare

I cannot find the end cap, is it possible if it snap near the end, for an end cap to stay inside somehow, causing further issues?

The cable end is stuck in the shifter. That's probably not good. It may rattle around in there without a problem, but more likely it will jam the shifter. Removal attempts could take hours and still be in vain. It takes fairly involved disassembly on a bench, good light, dental picks and tweezers, and good luck to get it out.

I once had one fall out after months of minor shifting problems.
