Major Arc is marketing a design that isn’t, and never could be, geometrically consistent. In this article, I explain what makes the design unworkable. The real question is whether they already knew about this. Continue reading Major Arc: a couple of problems
Using logic, one can realize that every truck (with a single pivot) turns the same, regardless of rake or any other characteristic. This and a few other points about truck geometry are tackled in this post. Continue reading Truck geometry (open access)
Wheelbase and truck angles are directly related. I want to show that the three variables: front and rear angles and wheelbase are sufficient and necessary to determine the turning radius of a skateboard, when tilted a given amount. Continue reading Pivot axis angles and wheelbase (open access)
This post is to show, in very practical terms and without abstract models, that reversing the rear truck is simply an option available for when we need it, not some fanciful eccentricity. I derive a very simple rule-of-thumb for those keen to experiment. Continue reading Turning radius: as a function of the rear PA angle
What might the idea of “gearing” describe in skateboarding? Should it be a catch-all phrase, or could it connote a simple, usable concept? I took this to the forum and had a heated discussion. Continue reading “Gears”: what could it mean?
What happens when you reverse the rear truck? Nothing much. Reversing is de-wedging and that’s all. Continue reading Rear PA angle: inverted rear truck
