I think that I'm going to change my flat bar bike over to a drop bar. There were no road shifters with hydraulic brakes until after I had put it together. (Or maybe they were so frightfully expensive we didn't move in the same spheres)
The problem appears to be that it is a 10 speed and the only hydraulic shifter I can find appear to be either 11 speed or Di2.
Were 10 speed hydraulic shifters even made?
I really would hate to have to change over to 11 speeds.
Next time you need a chain/cassette just go to 11:

Same hub, quick upgrade.
Andrew - I ordered that Potenza and it was not a hydraulic lever. It is something that is called "hydraulically optimized" and that has something to do with the rear derailleur and not the hydraulic disk brakes it appears.
It is made to use rim brakes or cable operated disks.
Is this what you received?

No, that is the correct one. You gave me a difference reference and until I read the entry in on the right side I didn't realize that they call the rear derailleur "hydraulically optimized." I suppose they use some sort of liquid shock absorber to keep the chain from jumping about on those very large ratio downshifts.
It is a lot cheaper from ProBikeKit too.
Campagnolo has always been weak on documentation and
terminology. In this case, 'HO' for a rear changer means the
upper pivot casting OD is minimized to clear a through-axle.
My pet peeves are using 'Record' for twenty or more
different products since 1960[1] and not marking the part
number on the part (something Shimano does rigorously).
[1]Typical telephone call here begins, "I have a Record Whatzit"
"Which Record?"
That is really odd - what does the oversized axles have to do with "hydraulically optimized"?
I looked through the manual trying to discover how you would bleed the brakes and there wasn't even anything on how to thread the damn cables though the levers to replace them.
If the Potenza didn't meet my requirements and cost so little I would change over to Shimano.

The first version had an upper pivot casting which could
interfere with big fat through axles.
Space is tight!

The current "HO" rear changer has a smaller OD on the upper
pivot casting.
