| Aerodynamics | ||
| Manufacturer aero claims | Cannondale claims the frameset and cockpit save 10 W at 50 km/h over the previous SuperSlice, a 14% drag reduction, worth about 25 s over a 40 km time trial at 50 km/h | Specialized claims it is as fast in the wind tunnel as the Shiv TT it replaced while about 500 g lighter. |
| Testing method | Wind-tunnel testing, developed with EF Pro Cycling | — |
| Tube profile | — | Truncated airfoil tubes from Specialized's FreeFoil Shape Library |
| Travel, maintenance & warranty | ||
| Travel & packing | — | On Shimano Di2 builds the seatpost only comes out after removing the EW-RS910 junction and unplugging the 1200 mm wire that runs down the seat tube. For bikes that travel often, Specialized suggests replacing that wire with a 700 mm and a 500 mm wire joined by an in-line EW-JC200 junction. |
