Derailer - Rear - Shimano, Alivio M3100 Derailers Digging through the parts boxes

Digging through the parts boxes looking for longer cable I find a set of Silver Downtube shifters intended for another bike

These are front and rear specific

That's why these are aluminum

All tubes are inflated and stored for 24 hours in order to test for air pressure retention
