Giant Syncdrive Pro spider replacement (absolute black)

[dhbomber]

Hello, I'm in the process of upgrading my bike (Giant Trance X advanced e+ 2). Little things here and there, that matter. I saw this cool and posh Spider/Chainring from Absolute black components made for ebikes, and as usual, they are made for different motor patters, such as bosch gen 3 and gen 4, spesh and others. My question to you guys is, what pattern does the Yamaha/Giant Syncdrive Pro have? Not the spindle, which I know it's isis, but rather the spider. What chainline would it be? Somewhere in my search I read 52mm?

Looking at some images on Google, isn't it just a 4 spoke 104bcd standard chainring?
Though you'll need to check if it's recessed into the spider's arms.

Its a proprietary bcd they use…which sounds like a bad thing to install, but their chainrings suppose to last a long long time. My question would be the chainline, and mainly the way it connects to the motor. Does giant use bosch type connection? Is it gen3 or gen4 style? Or is it it’s own thing

So yeah, it is a 4 spoke 104bcd chainring, but my question revolves more on the mounting pattern or "standard" of the spider. The spider itself looks to be made out of steel and is way overbuilt. There are multiple one piece options out there, or even Srams e bike chainring that I would like to install in the future. So still my question is, if the mounting pattern is that of bosch, if yes, is it gen 4?
