I was swapping a cage over on a 12sp xt mech and an all today and was really surprised at how rusty they were. I had new springs to fit so not a problem, but in all my years of spannering, I've not seen so much rust and dirt within a rear mech. The spring in question is the one within the mech where it bolts to the frame drop out.
Is this down to inferior metal? Poor sealing?
Quite surprised and a bit shocked tbh. Older mechs I've serviced after years of use have never looked so ugly on the inside.
