Halo Track Rear Hub 130mm Conversion Kit

Gusset 66C Campy Single Speed Convertor

If you've got a Campag multiple speed rear wheel and you want to run single speed for a while, just switch the multiple speed cassette for this simple cog and spacer kit. (*and ensure you can either adjust or tension the chain suitably).The large 10mm wide foot on the CNC machined and drilled steel cog spreads the load over a greater surface area than a straight single cog and will significantly reduce the risk of the cog biting into your alloy freehub splines.The superlight drilled, splined alloy spacers are offset to allow a degree of chainline adjustment.
