I am replacing a broken Shimano RD-2200, and trying to find the right part. How do I determine compatability? The largest sprocket is 26 tooth, and the cassette is 8 speed. Will anything by Shimano for an 8 speed work? Or do I need to get more specific?
Anything from Shimano with 8 speeds should work. The problems can only start when your cassete's biggest sprocket is too big (you are well under limit).
