Everything looks good but the seat angle is not progressive enough i don't think. 73 is SLACK.
The 73° listed is the effective seat tube angle (measured from the BB center to the seat clamp), but the actual seatpost angle is significantly steeper.
Ultimately, your body doesn't care about frame angles; it only cares about saddle height and saddle setback relative to the bottom bracket.
If you are on a size 58 with a high saddle extension, the seatpost follows that steeper trajectory. This means your saddle will not move as far backward as it would on a frame with a true, continuous 73° angle.
Seatpost angle (quickly measured in canva) 80°
Some gemini calculations:
| Saddle Height | Inseam | Rider height | Fit Context for Size 58 | Equivalent STA (Measured 80° Physical ASTA) |
| 700mm | 793mm | 168-175cm | Too low for this frame. Requires minimal seatpost extension. | 74.35° |
| 750mm | 849mm | 176-183cm | Lower end of the fit window. | 74.73° |
| 800mm | 906mm | 185-192cm | Target demographic. High extension activating the steeper ASTA. | 75.06° |
| 850mm | 963mm | 195cm+ | Extreme extension. Saddle position will shift drastically forward. | 75.35° |
