...begging for innuendo.
But yeah, try another dealer. Vdub heritage now stock some Lupo bits. But in europe (if they decide to sell to us Brits), there are still lots of brand new spares available. Lots and lots.
Have now finished mine. Found a reasonable donor wheel and had it re-trimmed in very smooth leather - nice result. Not sure whether or not to retain or sell my original wheel which is in great condition, but I don't think these are particularly valued as yet.
