White industries ENO freehwheels have become the go to for a bombproof freewheel. Fitting on to a standard 1.37" x 24 tpi threading it works with nearly all screw on freewheel hubs. With its sealed bearings it runs smooth as a whistle with a ratchet noise that rivals hope or king it sounds the part too.
This free wheel is fully serviceable and replacement parts are readily available when you ride and ride and wear out parts.
The ENO freewheel features a machined inner driver and machined outer gear case resulting in a freewheel that runs concentrically without the tight loose spots common to other freewheels.
