Your Looking tooooo Hard, Casson are the Aust Agents for Progressive and they supply to just about every Bike Shop in the Country, Including me.

They have one set on the shelf, Not a cheep item . Im sure there are other Brand out there.

You know the number

got mine off ebay, used the progressive site to get part number then just looked on ebay and ordered.

Try Rollies for Works suspension i find its a little better than progressive ....
