Howâs the grip and free roll? Theyâre foam core right?
Grip is phenomenal, canât comment on free roll because iâm running stupid tight belts and idlers. But they soak up the road like nobodyâs business, responsive as fuck and the efficiency hit isnât all too bad. I average about 21wh/km on 111s, getting bout 26wh/km on these. Totally worth it.

How far along will these be available? These would be good for my belted board. At least i can change the gear ratio on that board.

I guess I wont see them in my lifetime. At my age Iâm happy to still be riding.

Agree. Likewise, grip is only one factor when it comes to width.
Width does other magical things, like allow you to sail right over some railroad tracks on Venom Magnum 78mm wheels. This is solely because theyâre 70mm wide⌠⌠but thatâs wide enough to almost bridge this gap if you hit it at a small angle:
to scale, as much as possible, for common track ASCE 6040 60AS
And other holes and road imperfections can similarly be sailed over with wider wheels, because the wheel doesnât fall down into the imperfection as much.

Donât encourage him to rip off momentum boards hollow wheel please. Doug worked way to hard to have that done to him.

900g? Holy crap! Thatâs more than 2 MAD wheelz!

I always wondered why most cores donât have a better âlockâ with the urethane. I guess itâs because traditional downhill riding doesnât put much rotational torque on the core⌠mostly sideways loading instead.
For a dedicated esk8 wheel, I wonder if adding something like this to the core
Would prevent this type of failure

Idk how youâre getting that out of what I said, Iâm not proposing anything like hollow wheels.
I also own a set of those hollow wheels, the pro version. I support Dougâs journey and think theyâre a great wheel.

Wait are cores actually smooth on the outside?
I expected T-shaped anchors into the urethane to mechanically lock them together instead of solely relying on a chemical bond.
Not smooth but ribbed I think

The abec cores already have something that performs this function, but is designed differently than that sketch.
Yes, kegel (Orangatang, TB, etc) cores donât have a raceway and itâs why they can spin out.
No, abec (ABEC11, Zoobomb, etc) cores have a raceway around them, and would have to dismember the wheel from the inside to spin out.
I couldnât find a photo of the ABEC11 core, but this scooter wheel has a similar raceway around the core as the abec cores have.

So this is why abec has something over Kegel⌠Huh
âŚWTF sk8 industry wtf r u doing
Well the abec cores have thin and tiny spokes that seem really weak, thin bearing seats, and funky shaped holes, so each core has pros and cons. Round holes (like in the kegel core) are easy to drill, easy to CAD, and easy to fill with bolts or pins. And the bearing seats on kegel are nice and THICC. The abec spoke hole shape doesnât seem to make a lot of sense for esk8, maybe for downhill longboarding. But yeah the raceway on the outside of the abec core is dope.
Neither of these longboard wheel cores seem designed for esk8 use first and foremost.

Youâd think something like the TB110 would though, standardization only makes sense when it⌠Makes sense to do it that way.

Whether a core is kegel or ABEC is not that big of an issue. The mechanical locking of the urethane is the key to preventing delamination and is not hard to do. Just need a good core design (Not the TB110).
I want to make the core bigger for three reasons.
Cost
Weight
Contact area between core/urethane
The cost of urethane is getting really high. The more plastic that is used, the cheaper the overall cost of the wheel will be.
Urethane is heavy as hell. 900g like the TB130 is just waaaay to heavy. The right amount of urethane to allow for grip and cushion is all you need. Trampa really missed the boat on this one.
A larger core will result in way more contact area between the core and urethane. As long as the design allows for mechanical locking of the urethane, you should not have serious issues with delaminating.

I agree. All cores should just be Kegel with anchors or a raceway. Do away with abec.
Kegel mating pins donât leave enough room for bigger bearings. As much as I like standards, we probably need a new core. Abec and kegel styles both have serious issues. Also one thatâs licensed in a way that anyone may use it. And is designed for torque transfer.
