Curfboard: a closer look

#Curfboard: a closer look #longdistancepump #longdistancepumping #longdistancepushing #longdistancepush #longboarding #surfskate #distanceskateboarding #distanceskating #longdistanceskating

Purpose of the article Picture 1 The Curfboard truck came to my attention when someone asked me whether it makes geometrical sense in the same way that Major Arc trucks don’t. As soon as I saw it and the principle on which it turns (picture 1), I was intrigued. At first glance, there is no inconsistency about the mechanism: the design is foolproof and flawless. Still, I want to dig a bit deeper…

TKP trucks: history and quirks

#new TPK trucks: two ubiquitous but inessential characteristics, which truck makers ought to reconsider #longdistancepump #longdistancepumping #longdistancepushing #longdistancepush #ldp #dhlongboarding #changingangles #longboarding #slalomskateboarding

Image link The TKP template has been with us entirely unchanged for many decades, during which materials technology and consumer needs have evolved. While it has nothing significantly different to the RKP template (as I explained here), it is fascinating to me that the original form of the TKPs is preserved by manufacturers like an endangered animal species or an ancient ritual. Likewise, many…

Ideal truck angles

#newpost How do we decide which angles our trucks should be wedged to? In this post I explain my process. #longdistancepumping #longdistancepush #dhlongboarding #longdistancepushing #longdistancepump #ldp #changingangles #longboarding #slalomskateboarding

A very frequent question in online skate communities concerns the “appropriate” or “recommended” wedging; in essence the angle of the trucks. It comes either from beginners setting up a new board, or advanced skaters who purchased a new truck. This question attracts a downpour of apocryphal inaccuracies (note to self: start keeping screenshots). I’ve read that all TKPs should be wegded to have…

RKP-TKP: Term pertinence

Short post about why the terms "TKP" and "RKP" do not really tell us much about how trucks work. #longdistancepumping #longdistancepush #dhlongboarding #longdistancepushing #longdistancepump #ldp #changingangles #longboarding #slalomskateboarding

I tried to bring the images to a similar scale (using bushing width as a reference), so that we can see the TKP is clearly smaller. 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.Traditional kingpin trucks (TKPs) appear to originate from the trucks used for “quad” roller skates, before skateboarding was invented (hence,…
