RD-9070-SS correct? It's a maybe. On the specification side Shimano specs show you'll exceed the max rear sprocket of 28T.

You say you have a compact crankset, 50/34? Assuming that is correct then you'll also be outside the total capacity of 33T by two teeth.

So that's probably why no one wants to guarantee it will work for you. But it might. And plenty of people here say they have success going just over the specs. But again, no guarantee. It's your risk.

If you decide to do it, then you'll have to be certain the DR pully wheels will clear the bigger rear cog. If that can't be done then possibly a wolf link or some other hangar extender might help.

The most likely thing though is that you may not be able to rid yourself of chain slack when in the small front and the small rears.

But if it works to your satisfaction, then you are good. But with the cost of that cassette, I'd probably not risk it. I'd order one of the proper size and wait for it to come in. But if that cost is pocket change for you, then it's worth a look see.
