| Manufacturer aero claims | KTM says every detail was refined in the wind tunnel; no figures published. | Trek's Gen 8 tunnel figures (about level with the Madone Gen 7 and 11.3 W faster than the Émonda at 35 km/h) were run on the SLR with its RSL Aero bottles; the SL shares the tube shapes but ships with a two-piece cockpit and without the aero bottles, which Trek sells separately. |
| Testing method | — | Wind tunnel with a pedalling mannequin at 35 km/h plus CFD, in the SLR configuration (Trek's Madone aerodynamics page) |
