Yesterday I was riding some unknown old 50mm wheels I found.
They had a hard blue core and what feels like a 90a ish outer durometer. They sucked! Slow and felt really weird. They made a squishy sound like when cheap wheels deform around the bearing under weight load.
Yet I see in softer durometer skate sports like long-boarding, roller skates and inline that just about everything is dual durometer or harder cored wheels.
Why did dual durometer fade from ALL street and park wheels?
I ride mostly stf in various sizes and have some spf60's for cement bowl so understand that dual durometer are not really necessary anymore with these new school formulas. But back in the day they must have had some benefit?
I'm fairly new to skating, even though I'm old and crusty, so wasn't rolling when dual durometer and little wheels were common.
What changed? Manufacturing costs? and the evolution of hard fast urethane's with better rebound and grip/slide characteristics?
I read some manufacturers were research and developing super-light plastic core park wheels,, so is there still a future for dual durometer in street and park? Or just for softer atf type wheels?

Basically cored wheels
The cored wheels I have that are slow and squishy sounding look just like a powerflex wheel. I just aint seen cored wheels around NZ parks at all. I guess they all suck, not just mine.
Clouds and 80HD have a tiny plastic bearing seat, but its so small in diameter compared to other skate sport wheels and the cored park wheels like powerflex, darkstar, autobahn etc.
I had some 60mm Bombers and they were fine at 85a with no core.
Just seems weird how roller skating and longboarding are all plastic/metal cored and street/park are almost zero. Maybe its just the impact from doing tricks and landing on ramps.
At each meeting of materials an energy transfer occurs, at that border becomes a place where feel and feedback gets perverted by some sort of shudder or middleman sort of thingy ma bob
They just dont stand up to real skateboardings more varied wheel stressors, and offer poorly translated feedback to the rider as road forces get warped or shuddered at the border of materials
Its like bike frames snap beside welds, and too much gusseting and too many welds create a lack of shock absorbing flex in the frame creating a bony ride and low quality frame
