Longteng might be producing frames for Ribble. At first when I saw the photo I thought, that maybe one client just wanted to add a Ribble decal for some reason, who knows? After some time I wanted to check the frame again and then something clicked - I'm still not sure but that's just my theory. Why would they keep the clients frame in their showroom? My bet is - they could be a OEM for Ribble, or they worked with Ribble at one point. Looking at that Ribble frame from photo I sent it might be older project (not fully internal routed, strange looking fork etc.). The fork looks very similar to one on my Romet Huragan DISC 2023. For a fact I know, that Romet also works with Chinese OEM to get frames, I just could not find who it may be... It could be Longteng.
Alisa provided me with enough info about the frame, now it's time to sit and wait for some reviews since I'm debating between RD301, LC LCR017 and Hygge Model S since it's now EPS.
Also as a fun fact, Massi is using the same frame for their Arrow model as Romet for Huragan model
