| Fit & adjustability | ||
| Cockpit | Either a one-piece integrated cockpit (Forza Cirrus Pro Integrated or 4ZA CIP Integrated 2.0 on stock builds) or a separate bar and stem | One-piece aero bar and stem (4ZA Nimbus Aero) that sits down into the head tube |
| Seatpost type | Deda aero seatpost for Ridley (6 mm offset, 350 mm) | Deda aero seatpost for Ridley (6 mm offset, 350 mm) with an integrated clamp |
| Fit notes | A conventional stem and bar can be fitted with a transition spacer (Ridley code SPAAER4ZA012) to round spacers, or with a Deda Superbox stem. Ridley uses a steeper seat angle and lower bottom bracket than before, and a lower head tube with the integrated cockpit for a lower front end. | The Nimbus Aero cockpit comes in one width (360 mm c-c at the hoods, 400 mm in the drops) with three stem-stack heights (55, 75 and 100 mm; stock bikes use 75 mm) and several stem-reach lengths; up to 20 mm of spacers can go under it. Ridley defines stem reach as the horizontal distance the cockpit adds to frame reach. Because the seat angle is steep, Ridley advises choosing a size by the effective top tube rather than frame reach. |
| Aerodynamics | ||
| Manufacturer aero claims | — | 8.5 W less drag than the previous Noah Fast at 50 km/h (Ridley). Cyclingnews reports a further Ridley claim of 7 W less than the Falcn RS at 50 km/h. |
| Testing method | — | Ridley says all simulations were run on the complete bike including wheels, bottles and computer, at several wind angles. |
| Tube profile | Long, narrow profiles (UCI 8:1 ratio) in the fork and seat stays, shared with the Noah Fast | Long, narrow profiles (UCI 8:1 ratio) in the fork and seat stays, compensation triangles, and a widened down tube that shields the bottles |

| Headset bearings | — | IS42/28.6 top (1 1/8 in) and IS52/40 bottom (1 1/2 in), 45°/45° |
| Derailleur hanger | UDH (SRAM Universal Derailleur Hanger) | UDH (SRAM Universal Derailleur Hanger; Ridley code HANUDHSRA001) |
| Maintenance | — | Thru-axles are 12 mm with a 1.0 mm thread (Ridley code QRET124ZA046). The seatpost clamp (SPCAER4ZA007) takes a maximum of 10 Nm. A rotation stopper in the headset cover limits how far the bar turns, to protect the frame in a crash. |
