The snap/retaining ring out of my freehub that holds the pawls in has got old and tired and isn’t doing its job properly, so I need to source a new one. Trouble is that the hub (a Superstar Superleggera) is a while out of production, so was wondering if anyone could recommend a suitable alternative, please, as I have no idea where to start. Here’s a pic:

And the dimensions, as best as I can estimate them:
Diameter: 25mm
Gauge (thickness of the wire): 0.6mm
Hook length: 2.5mm
Overlap (how much the two ends cross): 6mm
Cheers!

No pic showing for me , can’t imagine the superstar hubs are unique in anyway.
Low end Dt , mavic , fulcrum and many others use a spring round the freehub to ouch out the paws

Can see the pic now lol

Somthing like this

Yes sorry was having trouble uploading a pic from my phone, anyway thanks for that very helpful, I couldn’t think what it would be called. Now that I know the name I’ve found an exact replacement kit from a Halo Supadrive hub, as it’s the same freehub system just a different shell. Cheers mate.
