Quick update! I asked Jack for the official FM316 geometry chart, and the numbers are pretty wild.
You were totally right about the "Forward Geo" inspiration, but looking at the Mondince chart, there is a massive and weird jump between the XS and the S:
Size XS: Reach 374 mm / Stack 559 mm
Size S: Reach 411 mm / Stack 563 mm
For comparison, the original Mondraker Arid only hits a 411 mm reach on their M/L size! A 411 mm reach for a Size S seems absolutely insane, especially for someone with my short wingspan (158 cm).
Do these Mondince numbers look legit to you, or is this a classic case of typos in a Chinese factory geo chart?
Assuming the 374 mm reach for the XS is accurate, it feels like it's the only viable option for my proportions, provided I ditch their 90mm integrated cockpit and run a separate 60/70mm stem instead.
What do you guys think? Am I reading this right? (Chart attached below).
