White Industries cartridge bearing two-speed 17/19 freewheel. New, $146.35/each

Part# 55161

White Industries writes: 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 (6 on the Trials model), we add an 8620 steel case-hardened and electroless nickel-plated outer gear turning on an Enduro chromium steel bearing.  We basically designed all the weak links out of the system.  And because everything wears out eventually, we designed them to be rebuildable.

ENO single and DOS ENO double freewheels feature 36 points of engagement while the Trials freewheels utilize a thicker outer gear (the base, not the teeth) and 72 points of engagement.

Our freewheel bearings are ABEC 3 or 5 grade depending on freewheel type, are made from chromium steel, and use a special Mobil XHP222 extra high pressure grease. 

Note: All freewheels can use either 3/32” or ⅛” chains except 16T ENO single and all DOS ENO double.
