Floating disc's

[daveinthailand]

Less jiggle if they are semi-floating, more if they are fully-floating. Both work as well as each other, far as I know. Fixed disks have to be thicker and heavier to resist warping as the bit with the pads on gets very hot and the bit attached to the wheel does not. Can not imagine a serious manufacturer still using fixed disks on the front..................................................... okay, Triumph bloody Tiger.

Rotational play would worry me a lot.
