I gather you are running the bike as a singlespeed, but not a fixed, correct? If so, there's nothing to worry about.

However, if you ever remove the "Front Freewheeling System" (that's what they called it) in favor of a standard crankset, be aware of this:

The FFS freewheels were equipped with an emergency catch that allowed them to freewheel if too much reverse force jammed up the system, such as getting your pantleg caught in the front chainring. As a result, if you try to slow the bike down with the fixie method of putting force on the pedals rearwards, the cogset will come unlocked, and begin to freewheel - a nasty surprise at the least time you want it.

If you run it with the original freewheeling freewheel though - you shouldn't have anything to worry about.

Take care,
