For those looking to order an X68, here is my journey so far.
As I posted in another thread, I ordered the X68 from TanTan on June 26th and the frame was delivered on August 19th. Roughly 7 weeks from order to delivery. It was delivered via UPS, as of yet, no additional cost for customs or tariffs. $719 for the frame kit and $160 for shipping.
The quality control (or lack thereof) for my frame/fork is questionable at best. There is a scratch on the right fork leg and small area on the seat tube just under the seatpost hole that didn’t get thorough paint coverage.
In the grand scheme of things, these are minor. The major annoyance is that the handlebar/stem does not fit around the steerer tube. From what I can tell, the diameter of the stem opening is undersized. I have an EXS Aerover handlebar/stem that does fit the steerer tube. The fork is the heavier fork, I think it weighed in at 406 grams.
Also, the clearance in the drive side chainstay for the Di2 cable (installing 12 speed Ultegra groupset) to the rear derailleur is very tight and took some effort to get the cable through. I haven’t tried running the brake hose through the non-drive side chainstay yet, so fingers crossed.
None of these are dealbreakers, but buyer beware.
