White Industries ENO Trials Freewheel

White Industries’ ENO Trials Freewheel is the single speed standard by which all others are measured. Starting with a driver made from 4130 steel that houses 6 heat-treated S7 tool steel pawls, for maximum engagement, White Industries added an 8620 steel case-hardened and electroless nickel-plated outer gear turning on an Enduro chromium steel bearing, essentially designing all the weak links out of the system. And because everything wears out eventually, they are designed to be rebuildable.
