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?

Here’s a couple of illustrations and a chart just to restate the obvious: tilt/turn is rake-agnostic. Continue reading Axle offset (aka rake): it doesn’t change axle turn
In this, I explain why the wheels travel the same distance, regardless of truck width. The main point is that the circumference of a circle is directly proportional to its radius. So, a circle with a radius x-times as long as another circle will also have x-times the circumference. So, the wheels trace curves of equal length on different truck widths. Continue reading Truck width: wheel travel
I have been thinking about truck geometry lately and I re-read Neil Carver’s article with more attention. The thing is, the article is dead wrong about what a positive/negative trail is. Continue reading Trail: Carver’s article “The science of the speed wobble”
The other day I was searching the internet about “rake” and speed wobbles and stuff and I stumbled upon Sabre’s webpage on “Truck Geometry.” It was a bit… messy. Continue reading Axle offset (aka rake): urban myths and skate companies
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
So, yeah, it exists! The pumping motion is described by these Russian mathematicians (and I must assume, avid slalomers).
The math exceeds me by far, but someone, somewhere, sometime might find this helpful, hopefully. Continue reading Peer-reviewed literature: the math behind pumping
