What is it? Why does it happen? And how to prevent it...
WHAT IS IT:
Wheel lift is when you go turn, and one (or in some cases, even more than one. But these cases are isolated, so ymmv) wheel lifts up. So, imagine for a second, you are riding your longboard...
... you are carving, schlarving, and then you feel it. It's like a hard rock, hitting the ground. It's subtle at first, but definitely there. This is what wheel lift is, and let me be the first to say, it sucks.
But, Why does it happen?:
Well, it's a spectrum right? On one end, you have too tight of bushings. With too tight (or hard) of bushings, they'll be so restrictive , that they will literally HAVE to lift a wheel. Whereas if you have too soft of a bushing, the bushing will be so soft that it will also, lift a wheel.
It's a delicate balance, but, it can be mitigated!!
So, how do you prevent wheel lift?
Pretty simple, really. You just gotta experiment with bushings. I like Riptide Krank and APS. But there are so many brands that people experiment with and enjoy. Abec11, Venom, Seismic, even 88WheelCo.
Now I'm not saying...
I'm not saying you should do this. However, if you are on a budget... just buy a single pack of 77a (or Similar duro) bushings and install them in your front truck. Then, tighten your rear trucks. This should feel near perfect, but do note it's not universal. But it is a good starting point.
