Halo Fix-G Hub - New Fixed Technology!

An ever present headache with “normal fixed hubs” is the assembly of a drive cog that is attached by a thread being pulled in both directions by the pedal torque. Of course, the traditional solution to avoiding the cog unwinding itself from the hub in the reverse direction is a left hand threaded lockring, butted up tight against the cog.
But, as many riders have found out, this historic system can be relatively volatile.
