These are T20 Tiger Cub Italian made Surflex clutch plates, which are sold individually. Excellent upgrade for your later model Cub clutch (ie: those with a duplex chainwheel). The lining on these plates is slightly thicker at 1.2mm than the original linings which were approximately 0.8mm. You can either have these skimmed slightly or maybe can use one of your old plates with two of these new ones. Unfortunately I am not aware of any plates being manufactured at the moment with the correct 0.8mm linings.
