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 clou is that the DOS ENO Freewheel
function while keeping the simple looks of a regular freewheel. To change the speed you simply move the chain by hand.
