Those BLUE caliper bits....

To (hopefully) lay this discussion about which is the fastest colour to rest: the answer is, in a dispersive medium like air, longer wavelengths of light have the higher velocity i.e red is fastest. Though, I suppose those of a philosophical nature might argue that, since black is the absence of light, its speed is infinite. In an experiment the black could be said to have been present the instant the test started, there's just a sort of Schrodinger's cat situation while you wait for confirmation that no light was sent.


None of this has any bearing on the speed of your bike of course. Nor does it stop red bikes looking a bit naff.
I trust this clarifies things.
