Back in rollerblading’s infancy, most of us started on Rollerblade TRS Lightnings. This was the skate that started it all. It was a recreational skate that people were using for aggressive skating. Since it wasn’t a true aggressive skate, we had to adapt to using this skate. The skate didn’t have much of a split system, which is the area between the 2nd and 3rd wheel. Space is needed there in order to lock on grinds. If there isn’t a space there then you’ll get wheel bite, which is your 2nd or 3rd wheel grabbing the concrete or rail. You’ll abruptly stop because there is no room and the wheels are too soft.
So how did we remedy this? Originally, we took skateboard wheels and replaced them with the 2nd and 3rd wheel. The reason is because skateboard wheels were naturally smaller and skateboard wheels had a harder durometer. This meant that a rollerblader would only be skating on the 1st and 4th wheel, while the 2nd and 3rd wheels didn’t touch the ground because they were smaller. We called this anti-rocker.
Soon after, inline wheel companies took notice of this and started making smaller, harder wheels dedicated to an anti-rocker set up. We no longer had to use skateboard wheels.
Riding anti-rocker meant that we we lost some speed and agility but we gained the freedom to grind anything. It also gained us some stability as well while grinding.
When aggressive skating, it just feels natural to skate an anti-rocker setup because this is what the sport was founded upon.
Riding anti-rocker was born out of necessity.
