Fixed cog replace by Freewheel cog
Anyone knows if I can change the fixed cog with freewheel cog of my Specialized Langster. So I have both side of freewheel cog with 16T and 14T on the other side.
Please advice.
Thanks Guys.

Undo the lock ring using a C spanner. It is a left hand thread.
Then unscrew the cog, which is a normal right hand thread.
You should use a chain whip to remove the cog, but you can get away with stomping on the pedal when it is in the right position to back pedal. Once you've managed to start it to move, it will unscrew by hand.
Then the freewheel just screws on, and doesn't need a lock ring.
