White Industries ENO Crank Arms: The ENO crank arms are machined from billet aluminum. The engineers designed a rigid box shaped crank resulting in generated power being transferred directly in to the crank arm rather than being dissipated and lost which is a common occurrence with a more flexible, less rigid crank design.
The chainrings (Sold Separately) are machined out of 6061 aluminum.
