In 2002 Doug White decided the world needed a better freewheel. Until then singlespeeders seemed to be content not knowing if their freewheel would last a week or a year, or fail a mile away from home or hundreds of miles. But what was certain was failure. Overnight the ENO freewheel became the standard to measure everything else against.
Starting with a driver made from heat treated 4130 steel that houses 3 heat treated S7 tool steel pawls on the Standard Engagement model, or 6 pawls on the High Engagement model, we add an 8620 steel case-hardened and electroless nickel-plated outer gear turning on an Enduro ABEC 3 or 5 grade chromium steel bearing packed with a special Mobil XHP222 extra high pressure grease. We basically designed all the weak links out of the system. And because everything wears out eventually, we designed them to be rebuildable.
