White Industries ENO Trials Freewheel - green locking ring

The freewheel utilizes a sealed cartridge bearing instead of a loose ball system. There are two advantages to the cartridge bearing:

• It is sealed from elements like mud, grit, and water.
• The bearing is nicely contained in one simple unit, easily pulled and replaced when worn.

The ENO freewheel features a machined inner driver and machined outer gear case resulting in a freewheel that runs concentrically without the tight and loose spots common to other freewheels.
A 36 point engagement system and a case hardened, nickel electro-plated outer gear case make this freewheel a perfect addition to your single speed.
Fitting for derailleur: Single Speed (3/32"")
