Given Kashima is supposed to reduce friction in suspension, putting it on a brake rotor may sound silly. But Galfer did exactly that for one of their motorcycle athletes and are doing the same for MTB. The Kashima doesn't affect the braking surface of course - just the inner part of a new two-piece rotor, called the Shark EVO V3.
The floating rotor is claimed to be stiffer and more robust than Galfer's existing one-piece discs, while dealing with heat better without warping. Needless to say, the Kashima has no performance benefit - it's just for show. Compared to the one-piece rotor, the braking track has been made slightly deeper radially to work better with Magura brakes, which have tall pads. The signature shark fins have been made smaller and more numerous to help with cooling without adding weight.
They come in 180, 203 and 223 mm diameters, with 6-bolt or center lock, all 2,0 mm thick. A 203 mm 6-bolt rotor weighs 205 g and costs 110 €. For a Kashima one, there's a ten Euro bling tax on top of that.
