Do you think a 11/32T cassette will work with it?

As far as I know, 29t cog is the max for Campy RDs.

There's a 2-part answer to the question.

One is the issue of cage length and the amount of chain to be taken up in going from big-big to small-small. The maximum safe number for a short cage RD is 30 teeth total. So the 11-32 has an 21T range and a 39-53 crankset has 14T for a total of 35T or well in excess of what the RD can handle. With a compact on front, it's worse of course. So, it requires a medium cage RD and It does not look like such a thing is available in EPS.

Second is the issue of upper pulley clearance from the big sprocket. Campy do make a 12-30 in 10-speed (which I have), and there is sufficient clearance. And here I'm assuming that the basic RD geometry is the same, which I believe to be so. So, it's possible there may be clearance, but it's going to come down to individual frame and hanger differences.

This is a long way of saying that I don't believe it's possible to do with standard EPS. Wider range gearing is possible with Athena mechanical which does offer a medium cage RD, so just maybe a cage swap is possible, I don't know.

Could put the long cage Athena 11 triple cage on the EPS RD. Still might not clear a 32 without a longer hanger.


isn't that what I said??
