Just found this one on the new factor, advertising seems pretty good

This one looks more legit as they offer the 45cm frame that came back this year with the v2. I asked F-C about this and he said it would be 7000RMB for the v2 but if I wanted a 45 it would be 12000RMB for "custom". Not sure about Yohobikes reputation.
In regards to mine it's been stuck in Singapore at "awaiting flight" since Dec 24th. But CanadaPost had a strike that really messed stuff up so I'm not really concerned.
I basically followed Oralmasters gameplan highest tier v1 Ostro from F-C > Ordered the legit 20mm top cap as he said it was crap as well as the silicone seat o-ring as it doesn't seem to have one in my photos and Oralmaster said he was missing it, as well as the I got the Factor bar tape to match from the same place.
I will post updates when it lands with detailed frame photos then full build weight etc as I will be swapping DA 9200 onto the frame.
