@snowy chain and gears are new, it jumps between gears on the 2-3 middle most gears and yeah, cabled.
Idk how to set cable tension tbh, rear derailleur is magick to me, 2x front derailleur is easy to grok, only thing that pisses me off is that the cables just break way too fast and it gets clogged by dirt (prob what happened rn)
