What makes a good BMX stem?
A good BMX stem is machined from 6061-T6 aluminium; 7075 is the noticeably stronger alloy and therefore the high-end choice. CNC-machined stems hold tolerances better than die-cast ones and keep their clamping force - forged is strong too. The bolts should be CrMo, because they hold bar and steerer under full load. Frontloader or topload is not a quality question but one of bar height and riding style. More on this in the category FAQ
