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

IMPORTANT NOTE: Threads for "Fixed sprocket Lockrings":
Our hubs must only be used with ISO standard 1.29" x24TPi L/H fixed sprocket 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.
