I had thought so too. Unfortunately they don’t. Just last week I ordered a new 7sp cassette, but through the ‘magic’ (read: confusion) of Amazon either I misread their ordering pages, or they misread my order. I received an 8sp cassette. So I looked up the spacing in the hopes I could use the 8sp. There is a slight difference in spacing. Enough that indexed shifting won’t work properly. Not to worry…one of my other bikes is an 8sp so I’ll just keep it on hand until it’s needed. Reordered, and now awaiting arrival of the needed 7sp (hopefully) cassette.
