But looking at it, I knew it needed a new set of cables and it wasn't adjusted properly. Just didn't expect to run into disposable parts (I didn't know they existed).
They weren't meant to be disposable - they are just very cheap and difficult to service, so disposal and replacement becomes a preferred option.
