Afaik, Asian body types usually means lower bikes with more reach (i guess on average Asians have shorter legs?). And the cycling population is young and demands aggressive bikes, whereas the west is getting old and people increasingly demand more relaxed geometries. That's my read of it anyway.
From the LT literature: Geometry design is more suitable for Asian type rider.
I don't think it matters much, but something to keep in mind.
The first time I saw the Asian geometry thing pop up was on the Seka Exceed. The founder of that brand is (allegedly since I dont know him) a prolific bike fitter and his claim was that because of shorter legs and arms that the bike geometry needed a lower standover and shorter reach. This was a huge marketing thing along with their messaging that their RDC frames were made in the same factory as Factor.
The result was the opposite of what Serge suggested since you ended up with a size range with relatively high stacks for their reach and seatpost position. Not at all unlike what Serge claims the western market needs more of.
The branded bikes from Bross, Elilee, etc, are all higher stack for their reach than most of their western counterparts, but this is more of a result of a focus on shorter reach rather than an intent; so it does seem like the smaller sizes end up better sorted than the larger ones. I think the open molds being low is a result of copying geometries of older bikes.
Regarding this frame. I feel like I have gone like 8 rounds with Alisa and still dont have an invoice to pay. This is really the factory ordering experience.
