Shifters, ders.
If you have either of the ders on the right and left, you can use with any 2009 and later set of shifters, 10s or 11s..main body outside of end knuckles..with older ones(center), nyet.
'Some' have said Potenza rear der return spring isn't strong enough for non Potenza shifters..I haven't seen that. Since the lever is just 'releasing' the cable to go to a higher gear, not sure how the shifter influences that.
AND, older 10s shifters, like 2008 and older? Use a 'modern' 2009+ rear der, like Chorus, even 11s..works fine.

The issue with the return spring tension isn't significant to the shifting functionality but the lifespan of the ratchet mechanism in the Potenza ergos. The escapement is plastic vs metal in the higher groupsets. So its a wearing out sooner problem - of course depends on usage.
