Here is a thing that has confused me for some time, so maybe some mathematically inclined person here has some insight on this. From what I read on the forums Q-factor is defined as the orthogonal (to the cranks) distance of the pedal mounting points. This definition doesn’t seem fully correct for several reasons:
It’s a distance, not factor (i.e. a number you multiply another number with)
With “zero” q-factor the number isn’t zero at all.
There is no word starting with q in the definiton.
Somehow I can’t believe that this is just a badly chosen name, there must be more to it than what I understand at this point.
(Feel free to link to other threads if this has been discussed previously…)
