| Aerodynamics | ||
| Manufacturer aero claims | About 7 W saved at 45 km/h by the new frameset against the original Magma with the same size, wheels and parts, plus about 10 W from the integrated handlebar against a standard two-piece round bar and stem (AURUM CFD estimates) | BMC says the Mpc. keeps the stiffness, compliance and aero performance of the Teammachine R 01 while saving weight. |
| Testing method | CFD across -10 to 10 degrees of yaw during design; Cyclingnews reports the design was then checked in the University of Valencia wind tunnel | Shapes shared with the Teammachine R 01, developed with CFD by Red Bull Advanced Technologies |
| Tube profile | NACA 0024 profile for the head and down tubes, NACA 0021 for the fork, seat tube and seatpost, truncated trailing edges; high seat stays and a flattened top tube | Deep horizontal shapes, Halo fork, stealth dropouts |
