Not hard at all really. If I had a zilla in front of me, could make a bracket quickly.
The hard part is if it can actually be made. If the bracket moves the caliper up or down then it wouldn't have good contact on the rotor. If it moves left or right, then it would interfere with the rotor.
Anyone know if the 250 spindles are the same as the zilla, if not, anyone want to send me a spindle or both and I can see what I can model up. I can even print a prototype to make sure it all works.
