Regardless of the reason - be it technical or esthetic - just how dangerous is it to mount a brake rotor the "wrong" way around? There are rotors from Grimeca with the arrow seemingly pointing in the wrong direction...
And there are some Hope Tech rotors that don't have an arrow at all...
I mean, in both cases, it would probably make more sense to mount the rotors with the "spokes/arms/whatever" pointing forward so that they compress rather than stretch out under braking, but,
from a non-competitive, everyday-use kind of perspective, is the direction the rotor is mounted in really
that critical?
