Right, as I don't appear to be able to post any pictures I'm going to have to describe it.
The cente of the strut has a blue cap in it, totally different to the photo I showed previously (the photo was from a suspension set up site).
The blue cap incorporates a nut and in the cente of the nut small (3mm ?) allen key head that operates on a ratchet.
On the outer of the strut top, almost like an aluminiun ring (surrounding the blue cap) is a silver cap with a number of holes drilled in it. It has a mark at 12 o'clock and then arrows indicating Soft to the left and hard to the right.
No matter how much I turn these nuts the cap remains flush.
Is this making any sense?
