30t would be pushing it for a short cage derailleur. You could try and use a deraileur hanger extender

Just a reminder: until 11 the measurement of the B knuckle to the top jockey wheel was almost always the same on long/medium/short cage. This is the measurement that determines if it will clear a certain size cassette in the rear. The cage length determines if a derailleur will take up the chain slack.

Working on a new road bike for my girlfriend.
It has a more or less complete Shimano 600 tricolore groupset, with a very short cage rear mech. Does anyone know if I can get away with a 30t cassette?
If not, what are the compatible options for a longer-cage Shimano 8 speed rear mech?
