The Promax "Impact Pro" BMX Race Stem - 1 1/8 Inch - Ø22.2mm is a top load stem for 22.2mm bars and 1-1/8" steerers. Promax forges it from 6061-T6 aluminum and CNC machines it afterwards, which keeps it light and very stiff, for racing and freestyle. The bar is held from above by a one piece clamp with four bolts. Choose the length as an option.
