Just thought I’d add my 2 cents to this group, as I finally received my frameset at the weekend. I ordered from Polar bicycle store on AliExpress a few months ago. However the frameset took a little longer than others,as I ordered the raw finish with the hologram logo which seems to be more difficult to manufacture and this seller was the first to have it on the market. Honestly I was a PITA customer asking loads of questions and being really picky about every detail, he answered all my questions thoroughly and promptly and never complained.
For a size medium/54cm frame weight was 898g, front fork uncut was 410g, 0mm offset seatpost was 125g and a Darimo nexum drag replica in 380x100mm was 284g.
The quality was outstanding and just as good as any western brand, perhaps even better. The facing on the BB shell meant there was no paint and the threads were super smooth. The handlebar and seatpost were a super tight fit with no play and the mounts for the calipers were also really well faced and the calipers were perfectly parallel with the rotors when I built it up.
Anyway here’s some pictures of the final build, came in at 6.7kg without bar tape.
