Bit of a disaster. Younger daughter seems to have trashed her rear derailleur, hit a big rock, chin wrapped around cranks and now there's insufficient tension in the jockey wheels to keep the chain in place. New mech probably, but finding a suitable one (1x11 Sram) locally is tricky.
Eldest daughter was dropped off at the bike shop somewhere (Teruel?) and they sorted her gears for her, just adjustment, I think. And sold her a GX SRAM rear mech which 'may' sort out her sister's gear issues, but I'm dubious. It's 2x11 and for a MTB, and I think the cable pull per shift is different from road shifters.
As I said before they left, it's only an adventure if something goes wrong. Otherwise it's just a bike ride.
Youngest daughter desperately needs a decent gravel bike. She's using her Trek Boone CX bike and it's pushed beyond its limits. Tyres too narrow, and gears a bit of a mish mash.
