OPTIONAL
FIXED GEAR/FREEWHEEL
a. You’ll need two optional tools that
aren’t pictured in this Build Guide: a
chain whip and a lockring tool.
b. Remove your rear wheel from the
bike.
c. The side of the rear hub with the
fixed cog/lockring has two separate
sets of threads on it - the first, closest
to the middle of the hub, has right-
hand (i.e. “normal”) thread and
accepts the fixed cog. The second,
closest to the outside of the hub, has
left-hand (i.e. “reverse”) thread and
accepts a lockring. The lockring stops
the cog from threading o when you
attempt to skid, pedal backwards, etc.
d. Use your lockring tool and turn the
lockring clockwise to remove it. Set
aside.
