| Fit & adjustability | ||
| Cockpit | One-piece Factor integrated barstem; the bar mount is separated from the steering axis so long reach doesn't need a long stem | One-piece bar and stem (Liv Contact SLR 0 Aero Integrated) |
| Seatpost type | ONE aero seatpost, 0 or 30 mm setback; adjustable head gives a 73.5-77° seat angle range; takes 7x7 and 7x9 rails | Integrated seatpost (Vector ISP), -5/+15 mm offset |
| Saddle position range | — | -5 to +15 mm offset |
| Fit notes | The barstem comes only 380 mm wide, with 80 mm reach and 120 mm drop, in five lengths (sizes 1-5, equal to 110-150 mm stems) and three high-rise versions with 20 mm more stack. Up to 15 mm of spacers fit, giving 35 mm of shifter-height range in all. Factor says the steep nominal seat angle still gives the same effective fit as the OSTRO VAM, and that every size has the same steering geometry, which avoids toe overlap on small frames. | — |
| Aerodynamics | ||
| Manufacturer aero claims | More than 8% faster than the OSTRO VAM, with the advantage sustained from 0 to 15° yaw (Factor) | 8.62 W less total resistance than the previous EnviLiv Advanced SL (complete bike, size M, 40 km/h, -20 to +20 degrees yaw; aero drag, wheel rotation and tyre rolling resistance combined) |
| Testing method | CFD iterations followed by wind-tunnel testing against a 3D-printed drop-bar HANZŌ ('HANZO Road') reference | CFD and wind tunnel, with Liv's 'Georgia' mannequin with articulating legs, modelled on Liv AlUla Jayco rider Georgia Baker |
