In preperation of potnetially selling the SP I've just ordered some replacement carbon sleeves for my bike.
The current pair are very faded and more importantly, on the LHS the bracket had become loose and allowed the sleeve to rub up against the swinging arm. Result of which is a nice 50p sized holes and 1 melted rear hugger and scorched swinging arm
The system is the lo-level, titanium race system and TBH, I was suspect of being able to find proper 'povic replacement parts considering it's age; however, a certain Norfolk based Kawasaki and Ducati dealer based a few miles outside of Norwich (I can't remember if we're allowed to mention names) can get a them! £318 inc VAT for 2 replacement 470mm sleeves, bands and rivets. Not bad and I was always planning to do it myself...it's not hard but then I had it confirmed that I'd do it myself when they quote £240 in labour to fit them for me!
