You had your choice of any bike in the shop but you made your selection based on potential upgrade options. The Press Fit 4124 will easily accommodate your handpicked rig with its press fit, 41mm diameter with 24mm axle BB shell.

The Press Fit 4124 is the "yes" component to "Is this compatible with my press fit 41mm diameter BB shell for a 24mm axle?"
