From most videos I’ve watched, I would assume the rear derailleur screws would be H at the top and L at the bottom. Likewise, front derailleur would be H to the left and L to the right. Is this always the case? My derailleurs have no markings and I don’t want to risk totally screwing up (pun unintended) my first attempt at tuning my gears. Any help really appreciated.
