Road Bike Frames, Wheels & Components / Re: Seraph Bikes Superlight 836g X68 - Alternative to SL8 Fakes?

Hi everyone,
I'm currently considering the X68 frame and I'm between sizes 52 and 54 based on my height (1.71m, inseam 82.5).
However, I'm leaning towards the 52, since I have relatively long legs and a short torso, and I prefer a more compact fit.
One issue I’ve come across: with a 300 mm seatpost, I might be cutting it close — especially if the minimum insertion depth is 100 mm. Based on my seat height, that wouldn’t leave me with enough usable length.
So my question is:
Can anyone confirm whether the X68 seatpost really requires a 100 mm minimum insertion?
The SL8 seatpost had only 75 mm, and I’d like to be sure this has changed.
If it’s really 100 mm, I’ll probably need to order a 380 mm seatpost with the size 52 frame.
Thanks in advance for any insights!
