The Sinz MX3 BMX Crank Kit is the bridge between square taper and a full 2-piece setup — a 24mm hollow chromoly splined spindle with forged 6061 alloy arms, 104mm BCD spider, and a sealed euro BB included. The 24mm spindle is significantly stiffer than square taper under sprint and gate loads. Sized and specced for Expert XL through Pro class riders who've outgrown square taper but don't need the full 2-piece Elite.
