OK, I'm stupid I'll admit it. What does the different diameter rotors
mean to the calipers. Can I by calipers for 160mm and use 180mm
rotors,
Or, more to the point, Hope claim 165mm for the M4s and I have 160.
Will it make any difference?

You'll need a different mounting bracket so that the calliper is the
right distance from the axle (so that the pads run in the middle of the
brake track on the rotor). Also, some forks have a maximum recommended
rotor size.

X-no-archive: No, I'm not *that* naive.

Ah, one of these things

I don't think I'm going to run into trouble, but just in case.
