hmmmm if the center of gravity is in the center wouldnt your weight act as resistance?

i think they would feel abit like sisemics if you ask me, i would say alot more practical then sisemics (which generally suck) i would love to ride a set and see how they go, the logic is good, getting it to work in a functional way is going to be very hard. i think gilbert is right that they would be a good freeride slash sorta truck

possibly the only original design since randal started making trucks ? what about grombiz ? oh dear , i can feel an onslaught of critisism comming now , lols

I don't understand how more lean would make the board drift more...

Please explain.

the most grip you can gain is when your board is not in lean at all (generally) this is because you weight is distributed among all four wheels equally and you are making efficient use of the total contact patch. The more you lean the more you weight is taken way from the center therefore giving less grip

yeah as tom was saying, have you noticed in photos of when people are sliding, how they are leaning right off their board so their core isn't centered over the wheels? basically you have moved your centre of gravity off your base of support (the wheels) so all your weight force is being applied on an angle downwards instead of directly down through the board if you weren't leaning. this will make your board want to drift out

remember that as you lean into a corner, more down force is put on your wheels due to g forces, causing the urethane to squash into the road. i would say your wheels grip more around a corner...

I'll ride them, have seen them evolve for the last few years, I will rip you all apart on them.

Its not any less evenly distributed then when the bushing are torquing the hanger during a turn on a conventional truck.

It has nothing to do with how far you are leaning. Equal and opposite forces you see.
How hard the edge of your board is pushing back when you lean is how hard you are pushing on the wheel on that side.

If you take your trucks and remove the bushings, there is nothing to push back on, and the weight will be evenly distributed between the wheels no matter how far you lean.

You can easily test this if you have two scales.
Or even one scale, and a platform equal in height.

Actually, since these trucks seem to generally have less resistance, In theory they could grip better then conventional trucks.

this is a mega nerd thread right now, its funny as fuck. a wise man once told me: Arguing over the internet is like running in the special olympics; doesnt matter if you come first your still retarded...

i'm merely speaking from personal experience, i know that my 42degree randals which lean more slide alot easier than my 50degree. while i dont fully understand all the forces that act on a board and truck, it seems intuitive that if your board is leaning more, and if lets say you apply a force down perpendicular to the deck, then there is more force pushing it horizontally sideways, hence making it slide out. Again, this is all just my intuition and through personal experience, and as much as i love physics, when it comes to skateboarding i trust my experience more than what a free body diagram will tell me.

and i would hardly call this arguing jacko, we're sharing what we personally think about the truck based on what we understand from we understand from other more conventional trucks, which I think is what this thread was made for?

LOL, Yes, Certainly.

Real world trumps all!
