Marin released a new Gestalt a couple of years ago (2024 Marin Gestalt X), which has the geometry that I really like: 1) really slack head angle (67.5-deg); 2) upright seat tube angle (75deg);
Any Chinese carbon frames hit these specs? especially the slack head angle. AFAIK, you have to use a 29er hardtail frame for that kinda slack angle. that those 29er hardtail frames (like SP Cycle M09, HA 67-deg) require 520mm (Axle-to-Crown) long fork and not the 400mm-440mm gravel carbon forks, and if you use the shorter gravel carbon forks, the head angle will increase back to about 70-deg.
