Well of course you never know if such things will actually make it into production.. but this one seemed simply stunning to me and I wondered why nobody considered it in the past (not that I know).
I ready about this new dual disks brake system on evo and I think it deserves to be seen! I just see positive points: more cooling surface, lighter pedal, more force applied, better feel, lower diameters so weight won't really improve...
