@Nick_S I have an SKS Rennkomplainer and I hate it. I sold the EVA head because it doesn't fit. It's the Renn I've got the Zipp crack pipe on.
The Silca looks exactly the same as the Zipp. I assume they're the same so I might be able to use the replacement Silca elastomer in Zipp. But I still hate them. I've had two Hirame copies in the past and they're too big from memory which is why I swapped to the Zipp.
It sounds like you have pretty much exhausted the options. Maybe just fit the new rubber to the Zipp and move it to another model of pump, e.g., Lezyne?
i loathe my renkompressor head. i thought i was the only one. is there a decent head that i can change to on my renkompressor as the pump itself seems pretty good.
