    What is headtube angle usually based on?

    If you look at the Switch on the Rocky Mountain website, you'll find that one version comes with a 170mm fork, and the other with a 150mm fork. Both however have the same amount of rear travel and, of course, the same headtube angle. I always thought headtube angle was based on a built-up bike with fork. Rocky Mountian obviously doesn't do it this way.

    How do companies typically determine a frame's headtube angle? Is there any way to standardize the criteria?

    headtube angles are simply the angle of the headtube vs the ground fully built up. Either RM didnt correct their figures for the different models, or the framesets are actually different and corrected to the particular fork do have the same angle for each model.

    there are small hydro pumps at the top and bottom of the headtube that are scientifically designed to self-adjust to any terrain so the headtube is at a constant while the rest of the bike moves about......
