The R80g/s - and I presume some other models - has a ring made of some mysterious white substance on each stanchion immediately below the bottom fork brace. It is used to provide a base for the top clamp fixing the gaiters to the stanchion, but deteriorates at an alarming rate, turning to unusable mush. Thus my calling it 'white cheese', for it may as well be made of that! I thought of turning some similar items from delrin, a much more stable and rigid material. The idea being to turn the delrin to the same dimensions as a new white ring but with a diametrical gap the allow for compression on to the stanchion. Has anyone tried this modification? If so, any comment on what to do or avoid. These things drive me crazy!
