White Industries Singlespeed High Engagement Freewheel - 18 teeth - black lockring

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, White Industries 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. White Industries basically designed all the weak links out of the system. And because everything wears out eventually, they designed them to be rebuildable.
