| Aerodynamics | ||
| Manufacturer aero claims | Specialized claims it is as fast in the wind tunnel as the Shiv TT it replaced while about 500 g lighter. | Specialized claims it is nearly a minute faster over the Kona course than the fastest possible 2011 Shiv setup, and minutes faster than a typical one. |

| 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. | The basebar folds down to the fork and the cockpit unbolts for packing. |
| Packing disassembly | — | Unplug the single Di2 Y-wire under the nosecone and remove the two tower nuts, then lift the extension socket (extensions and arm cups) off the fork; the tower nuts go back on to hold the spacer stack. The basebars can be rotated down alongside the fork by loosening their two wedge bolts. |
