Some thoughts on building it up:
As said, packaging is top, kind of new standard!
Extra box with items, screws, spacers…etc
Installation guide in “real” English, very detailed!
Frame/ painting top….t47 interface v.well faced.
Flat top mounts…could have been slightly better…rear without adapter should be fine, with it a bit of sanding. Front ditto.
Boxes on top- and downtube look like being cut out afterwards with “template”. Not sure tough just guessing, but seems reinforced…quite simple open/close mech.
As it’s not a fully compartment option you have to use the bags which sit under and are screwed to the cover.
I find them a bit small…but have no comparison.
I did change the steerer bearings with a stainless steel option, size is 52x40 45/45 … one 7mm, other 8mm
Installation wants you to put 8mm at bottom, but I reversed it, as I found the gap more pleasant the other way round.
And they still use this steerer tube metal spacer where the bottom bearing sits at the fork .
Elsewhere no issues with building it up with my wheeltop EDS TX 2x group.
And I opted for the road bar/stem combo in 400/110.
Cheers…
