Profile Magnutanium BMX Cranks
Best lightweight crankset for smaller competitive BMX racers.
These are purpose-built for the weight-obsessed racer who needs maximum stiffness without the bulk. By stripping away material for extreme lightness, they sacrifice the durability required for street or dirt abuse. They are a specialized tool for speed, not a do-it-all component for the park.
