TD04GT Posted September 22, 2018 Share Posted September 22, 2018 I've seen many posts saying you need spigot rings to centre the astra discs used on a levin twin pot setup, does anyone actually know the specs or sizes of the spigot rings? If I was to bore the inside face of the discs which fit over the hub to within 0.5mm of the diameter for a snug fit, would this make the spigot rings unnecessary?

SpoonalTap Posted September 22, 2018 Share Posted September 22, 2018 I just took my hub off and gave the disc and hub to a engineering firm and asked them to make me spigot rings. As long as you've got a way of centralizing the disc on the hub when bolting everything together then I would imagine it would be ok without one as once the wheels are bolted on the disc its sandwiched between the wheel and hub and it's not taking any weight like the wheels but for my own peace of mind I wanted to get rings made.

You would 100% want a permanent spigot ring, a huge amount of force goes through the disc when being clamped and could easily be pulled off center especially when things get hot. For the sake of paying maybe £10 or so for some spigot rings it's not worth the risk imo. Quote Link to post Share on other sites
TD04GT Posted September 22, 2018 Author Share Posted September 22, 2018 Thanks for the advice lads. I think I'll send the hubs and discs along together to have them lathe'd and spigot rings made up then. Quote Link to post Share on other sites
