Saw this while perusing the Robber's of south Wales' website recently:

Not cheap, but could be worth it? It looks a lot like the Aus spec bikes oem filter (that is not available to order in Europe for some strange reason?!)...
Personally I still like the DNA filters, and they were very reliable in the dust on Heroes' - nothing came through, but then I was changing them every day... I say 'I' - I mean my spanner monkey of course, I was eating caviar and drinking fine wines...
Ta-ra!
