| Overview | ||
| Brand | Rose | Trek |
| Build | Shave FFX Dura Ace Di2 | Madone SLR 9 AXS Gen 8 |
| Build notes | Colours ghost pearl and liquid racing green. Rose quotes about 6.6 kg (±5 %) for the Shave FFX in size M, liquid racing green, without pedals, on its product pages, but 'from 6.8 kg' on the model page, so no build weight is recorded. Rose's UK site doesn't list the Shave FFX, so there is no GBP price. The 4iiii power meter's model isn't named beyond being dual-sided. | Claimed weight with TLR sealant, no tubes, no bottles or cages. Trek also sells this build in limited 'The First 50 ICON' and 'No. 76 ICON' paint editions (US$15,999.99, €14,399, £12,680). |

| Manufacturer aero claims | 205 W at 45 km/h in TOUR's wind tunnel (size M/L with RC55 wheels and 28 mm Schwalbe Pro One Aero), 10 W less than the Rose Xlite 06 (215 W) — figures Rose quotes for the Shave FFX | Trek says the Gen 8 is about as fast as the Madone Gen 7 when fitted with its RSL Aero bottles (0.1 W faster at 35 km/h in its tunnel table) and 11.3 W faster than the Émonda as sold, with most of the gain over Gen 7 at low yaw. The RSL Aero bottles save 1.8 W at 35 km/h against standard 21 oz bottles. |
