| Manufacturer aero claims | Berria: 3% less drag (4 W at 50 km/h) in a headwind and 11% less (10 W at 50 km/h) in a crosswind, from wind-tunnel tests at the Politecnico di Milano; the frame, fork and bar together account for the 4 W head-on | 15.9% less drag than BH's previous G8, about 5 W at high speed (BH) |
| Testing method | Wind tunnel (Politecnico di Milano) | — |
| Tube profile | Smaller tube sections with less frontal area ('Aero Shape Efficiency' shaping) | Kamm-tail tube shapes; the 'Air Bow' fork and seat stays leave a wide gap to the wheels |
