    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.

    Halo thought there has to be a better way: A splined hub body (with cogs that slide on) and an independent lockring that never has to handle rotational forces from the drive.

    "The Fix-g hub is great! it runs smoothly as the previous Halo hub but the fact that you can move the sprocket for a perfect chainline is great and you can feel the difference straight away. Also, it's really easy to do, everyone can do it without a mechanic’s help, I think you should advertise this and make it clear for everyone, people don't have to be scared of a new technology." Ivan Fiorilla, 5th Floor riding club - London.

    Halo Fix-G hub:
    The Halo Fix-G hub features a fixed HG spline machined as part of the alloy main hub body, with a conventional internal thread for a standard HG type lockring (with easy tool fittings). + options L/H side for conventional fixed or freewheel threads.

    (Note: Must ONLY ever be used with 7mm base Wide Foot cogs such as Gusset Double Six cogs to avoid the cog biting into the alloy splines on the hub.
