Note: General Fixed cog check: 
for correct fixed use, the fixed cog should NEVER move on the hub when pedal force is applied in both directions.
i.e. if the cog moves, then something is wrong.
Continued use with a fixed cog that moves will result in damage to the hub.

IMPORTANT NOTE: Threads for "Fixed Cog Lockrings":
Our hubs must only be used with ISO standard 1.29" x24TPi L/H fixed cog lockrings
Do NOT USE French (1.32" x 24TPi) or Italian (33 x 1mm) standard lockrings.
The larger diameter French and Italian lockrings may appear to work. but. will strip the threads from the ISO hub.
