Halo Double Fix-G Track Rear Hub – 48H

An ever present headache with traditional fixed hubs is the assembly of a drive sprocket that is attached by a thread being pulled in both directions by the pedal torque. The usual solution to avoiding the sprocket unwinding itself from the hub is a left-hand threaded lock-ring, butted up tight against the sprocket. But, as many riders have found out, this system can be quite volatile.

…and the solution – an HG splined hub body, with sprockets 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 or swap and will take down to 12t cogs, it's genius". Ty at the Footdown – www.thefootdown.co.uk

Note: The HG spline must ONLY be used with 7mm wide "fat foot" sprockets such as Halo Fat Foot sprockets or Gusset Double Six sprocket to avoid the cog biting into the alloy splines on the hub. Regular width HG sprockets should NEVER be used.
