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. Accommodates 3/32″ and 1/8″ chain.
