Maybe my posting site isn't here, as my X68 has been replaced by a Yohobike.
After two days of putting the bike together, I was able to pass all the material to the new frame.
At the moment I can provide a couple of information about both since I have not yet driven my yoho.
The seatpost is fully compatible, can be exchanged between both copies, the address headset has the same flaw as the x68, and a final information that may be interesting to some.
After weighing the uncut Fork, its weight was 400 grams with paint, with the same components, the bike weighs about 150 grams more than my old X68.
