Stooge 3-link truck: skating in never-never land

A fantasy steam-punk machine that looks kinda cool, if that’s your thing, until you realize it can’t possibly exist, because it violates the laws of nature and logic. Continue reading Stooge 3-link truck: skating in never-never land

Skateboard geometry: balance line

The basic idea I’d like to convey with this post is that a skateboard always balances on the line that connects the two centers of the axles of the trucks. Continue reading Skateboard geometry: balance line

Ideal truck angles

How do we decide which angles our trucks should be wedged to? In a post addressed to beginners, I propose a process and explain the reasoning behind it. Continue reading Ideal truck angles

Wheelbase: the case for short decks

In this post, I want to make the case for a turn to shorter decks. First, I explain why long decks are redundant, then I enumerate the advantages of short-wheelbase decks and finally I attempt to answer exactly how short decks should/could become. Continue reading Wheelbase: the case for short decks

Pivot axis angles and wheelbase (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)

GBomb’s Torsion Tails: a closer look

The Torsion Tails are a line of rear trucks made by GBomb specifically for platform decks. In this post I examine the design. Continue reading GBomb’s Torsion Tails: a closer look

Curfboard is a simple but ingenious design, which shows that innovation can still happen in an oligopolistic, stale market. It would be better though if Curfboard’s marketing steered clear of speciousness and didn’t thus undermine its own reliability. Continue reading Curfboard: a closer look

TKP trucks: history and quirks

The TKP template has been with us entirely unchanged for many decades, during which materials technology and consumer needs have evolved. However, some things that are characteristic about TKPs are not also essential. In this post I want to examine two ubiquitous but not defining characteristics of TKPs, which truck makers ought to reconsider. Continue reading TKP trucks: history and quirks
