willv – I had a similar issue, to start with the rear triangle came in at nearer 125mm, not sure if this was crushed in transit or whether it was a production issue but pace replaced no questions, the wheel set to one side as well but I guess this could have been due to the alignment issues with the rear triangle.
Aside from that, lovely frame, climbs awesome.
One other niggle, the owners manual i got with the frame said the 405 has a 68mm BB shell, but its actually 73mm….
