Cx70 top pull with 7800 shifter?

[Dead Man]

I know one of the 10s DA iterations is noteworthy for having a unique pull ratio that doesn't jive with other road group ders.... but googling around on my phone I'm not finding much help..

Cx70 top-pull work with 7800?

I should also add this is gonna be set up 1x front, so my only purpose for even plugging a front der on is to act as additional chain derailment prevention, and hopefully on-the-fly re-railing. If it'll push the der over far enough to put the chain back on the inside ring, that's all I'm after...

Thanks!
