Shimano ships components to shops planet wide. square taper has been made in the millions per year for decades.

Factories like those in Asia making many brands each, get truckloads from the component factory..

just buying one has a higher cost ... any how get a cold forged crankarm ,

and dont hit a pedal on the ground in a corner or let the fixing bolts or pedals get loose , & they will last decades.
