Hello
I went on a roadtrip with my family and we took our bikes. I'm riding a 15+ year old MTB Scott and I snapped the chain on the first day. Since then we cleaned the drivetrain to prohibit further malfunctions and today I broke the chain again. The chain snapped because while pedaling the drivetrain kind of "skipped" which was happening repeatedly especially when I tried to pedal harder. After the first snap we bought a new chain and thought that maybe the chain was worn and that was the case so we tried different lenghts i.e. we shortened the chain multiple times but the skipping problem was persistent. We shortened the chain to the point of not being able to switch to some gears and the problem still persisted. So we elongated the chain back and I snapped it today while pedaling uphill. Is there any way to stop it from happening again?

Looks like you are using an incorrectly sized chain. Confirm chain u put on as a replacement?
You have 9 cogs. Is it a 9-speed chain ?
“Skipping” is usually caused by a new chain on an old, worn cassette. You may need a new 9 speed cassette also.
If those pics are of a clean drive train, yikes! 😳
The snapping of the new chain could also be the locking links not being fully locked. Kind hard to tell with the pics.
Your big ring and cassette are worn out, and will no longer work correctly with new chain.
