Halo Double Fix-G Track Hub

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."Halo's HG spline system is so obvious and brilliant that other brands must be kicking themselves for not thinking of it first: it can't slip or thread; it's way easier to fit/swap and will take down to 12t cogs, it's genius". - Ty at the Footdown (www.thefootdown.co.uk). Oct 2011 "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..."
