Hello, so I have a Sram gx eagle set up on my bike, now on my derraileur I’ve noticed it said clutch bearing roller, what does this do? I’ve also noticed a button with a picture of a lock on it.. is this meant to lock it in place when pushed in? Although when I did it it just pushed back out, so how does this work??
