No not really, what I meant was that this is the like a screw on single speed kit, you can use freewheels for the front or back depending what gear ratio you want. The advantage of having a freewheel on the front is for better ground clearance they mainly used on Mods and Stocks for natural terrain. Also another advantage is the weight and engagements of the freewheel compared to a normal mountain bike hub, engagement is like how long it takes for it to kick in so if its got a higher engagement like this trialtech freewheel:

Also the weight is a difference as freewheels and screw on hubs are normally lighter than quality freehub hubs.
