Hi i have a pair of black mavic 717 xc's on my modern bike. They looked great in their blackness on my white on one but i've just replaced the frame with an airborne and the black doesn't suit. I know i'm being a tart and its a bike for riding not looking at but if they are easy to strip i'm going to have a bash. I don't have any nitromors or drain cleaner in stock so before i rush out and buy both i'm better off knowing what it is. I'm guessing its paint but happy to be proved wrong
