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
In this short post I want to explain why I think the terms “TKP” and “RKP” do not really tell us much about how trucks work. Continue reading RKP – TKP: term pertinence
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)
Occasionally, people assert that TKP trucks (i.e., trucks with significant forward rake) turn “progressively,” while RKP trucks (i.e., trucks with minimal rake) turn more “linearly”. That, at first glance, can only mean that the trucks resist turning in such ways. In this post, I check for patterns in the way trucks resist when a rider leans on a skateboard. Continue reading Skateboard physics: squeezing bushings

Just for future reference, I measured the KP/PA angles of a few popular trucks. Here’s the results. Continue reading KP/PA angles
