KRC crank hubs are CNC machined from 6061-T6 aluminum, lightened with lightening pockets, and are anodized black for a sleek finish. KRC revolutionary R-Lok crank system allows for an endless amount of crank pulleys to be stacked and locked together. This provides for a more positive and lightweight drive than a conventional mandrel system. The R-lok system is more concentric and truer than the conventional pin-drive systems.
