Compared with Gen 4, stack is 10 mm lower in every size and the old 51 cm was replaced by 50 and 52. | The barstem is chosen at order in 36, 38, 40 or 42 cm widths and 80 to 140 mm stem lengths (10 mm steps), with 80 mm reach and 120 mm drop; the drops flare by 30 mm. Factor also offers the Integrated Aero Barstem with Extensions (AB03) as an upgrade. Saddle rail clamps take 7x7 and 7x9 rails. A 45 cm size was added and the seat-tube angle is 0.5° steeper than before. |
| Aerodynamics | ||
| Manufacturer aero claims | Yaw-weighted drag 0.003 m² (CdA) lower than the Gen 4 SuperSix EVO, weighted at 40 km/h road speed. Cannondale says it is faster than many pure aero bikes while weighing up to a kilo less. | 70 g less drag (a 7 W saving) than the previous OSTRO VAM frame; Factor says it outperforms its rivals in the wind tunnel |
| Testing method | CFD and wind tunnel. Cannondale combines drag-versus-yaw tunnel data with a modelled distribution of on-road yaw angles into one yaw-weighted drag value, and quotes power only with a speed. | CFD simulations of dozens of head tube profiles (Rapid Iterative Design), then rapid prototypes verified in the wind tunnel and real-world testing |
| Tube profile | Truncated NACA aerofoils, each tube shaped for its own structural and airflow needs; designed with the Gripper Aero bottles and CarbonGrip Aero cages | Airfoil-type profile along the frame's waterline; 15 mm wide seatpost shaped for the airflow off the rider's legs |

| Derailleur hanger | UDH (SRAM Universal Derailleur Hanger) | — |
| Maintenance | — | The threaded T47 bottom bracket takes CeramicSpeed bearings. The Di2 battery is reached from behind the bottom bracket rather than through the seatpost, so the saddle height isn't disturbed. |
