In my case........nailed it!!! Although apparently they are like the shimano Ice tech RT99 rotors. The coloured bits are "cooling fins" to dissipate heat, only on these they are coloured on the Shimano they are not. They even have a video to show you it works so it can't be wank! :whistle:what's the deal with the rotors, the coloured bits look like they are just for wank as opposed to anything else?
