| Aerodynamics | ||
| 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 | Ventum publishes no drag figures. The front end, inspired by the Tempus TT bike, extends the leading edge ahead of the steerer and uses an hourglass head tube to cut frontal area; the fork legs are deeper. |
| Testing method | Wind tunnel (Politecnico di Milano) | — |
| Tube profile | Smaller tube sections with less frontal area ('Aero Shape Efficiency' shaping) | — |
