Hmm yeah I wondered this too, and what if the wheel isn’t poured perfectly and it’s off balance? One easy test is just no-load spinning up the wheels to see how much they expand on their own. If the material is the right hardness, you’d think that at higher speeds you’d actually get more grip 
Are there any close up photos of these wheels?
I’ve got a pair at my house if anyone wants to borrow

Abec or kegel core?
I’d like to borrow. Could ride them and then pass them along to others to try if you’re game. Like a socially distanced hollow wheel beta Doobie.

As for track racing. Not in the same class as rubber, grip wise.
There is a nitch here. Focal point being a good ride quality. Rolling resistance and durability would assume being compromised over traditional Thane. If durability plays out good I think most don’t mind trading some PU range for for a bit more grip and less road harshness. They may work well for PU short track class racing. Needs to be put to task.
Hope to see these breaking traditional thoughts and process.

Hey @DEEIF, this is made from urethane. It’s very difficult to get SBR or Rubber made for overmolding.
@fessyfoo definitely need to put it on a board with more power. That’s why I directly swap on people’s board so they can get a true back to back feel of the wheels
@kevingraehl is a boss
If you want a race setup, you shouldn’t choose anything with PU. There isn’t a race car in existence that uses PU. Only SBR. I chose PU over SBR because I wanted to get the best customer experience - reliable, great wear characteristics, and relatively low cost (I can make it at a reasonable cost and pass the savings to the customer). I hate running into punctures and SBR wears quickly.
You can’t really design an SBR with the geometry in the current wheel. There are other ways, but the manufacturing cost would be very high and no one would ever buy the wheels.
@davidbonde There is a big tongue that prevents the cover from coming loose at high speed
@ShutterShock this is made from injection molding, so it will be very accurate. within .010 in all the critical areas.
@MoeStooge I hear you come to the intro to speed event. I won’t be there next week, but I should be able to come the week after. Come try them out!

Yes that’s it did better at the search than me.
“If you want to keep in touch and get a discount code when we start production, then go to our landing page and sign up: https://free-range.landinglion.com/momentumwheels/ ”
Also called momentum. Started at similar times my mistake. you use the same photo on your website so I’m getting very confused
Are these 2 videos not of the same person riding the same board in the same car park?

Now that I have proven that the momentum wheel has evolved in to the hollow wheel
How did this
that @dth2m5 said and provided videos as evidence was the most commutable, best grip, better range witch I was referring to when I said
Because of the lack of cushioning the depth of the urethane would provide compared to tb110 wouldn’t be replaced by a larger core no matter what shape the spokes are
How did it evolve in to this? @TheGoodMomentum
yes and i couldn’t fined any thing in there
I can see how the new design would provide
-
Comfort by the Air gap over solid urethane
-
Range by the cone shape producing a smaller contact patch
-
Grip increased in corners with lateral force de forming the wheels providing a tempery larger contact patch.
-
What about under hard braking and acelaration? Wouldn’t you have reduced grip then because of the reduced contact patch of the cone shape?

I figured the low density would make it conform to the road and offer more grip than a harder wheel.
Would be cool to see the actual contact patch by standing on the board while filming through a piece of glass.

Bare in mined under braking the center of gravity is moved forward providing less downwards preser on the back wheels making the cone shape work agains you more than a straight wheel.
Be interesting to fined out how it reacts in reality compared to other wheels

Oh yeah, that is what you’re talking about? Yep, that was me! How did it evolve from that? Well, if you could ask me a more specific question, then I can answer. That is such a loaded question and I wish I had more time to answer such a broad question. My answer is just an epic shit load of testing, epic shit load of talking to people, epic shit load of beta testing, and epic shit load of spending money on R&D, and 2 years of that.
Acceleration & Braking:
It all depends on your board, but even on high powered DIY boards, Metroboards, etc, you don’t see people doing standing burnouts. It does have less of a contact patch, but it’s still a matter of weight distribution and I have not heard of any of my beta testers or experiencing it myself where the wheel starts braking traction on hard braking.

Also adding to contact patch, you see a ton of wheels with a ton shape, not the same cone shape as my wheel, but still a cone shape from Cloud Wheels to Pneumatic wheels.
The measured contact patch when just going straight is about .8-1", depending on how heavy you are. It’s more than a brand new Cloud Wheel., which is much less than .8" and closer to .5"

This is the sort of stuff I should be making videos on, so I probably should try and get my hands on some.
Probably can’t put in through its paces on the riding, but there’s plenty to talk about.
If there’s a set being borrowed and passed around, I’d be super down to get in line for that.

Gotta go on the sand / dirt to do burnouts

So the product is untested in regards to traction loss under Breaking? I get longitude grip is irrelevant in analog boards but it’s a huge factor in electric boards and one of the biggest weak points of urethane. It’s also the limiting factor when setting motor -settings when tuning.

If you want, I can do a brake test video compared to all the other wheels too. Is that what you’d like?
Every-time anyone takes the wheels out to try, they are braking. So it is tested.

Yes but not to the limit of traction. if your going to state “most grip” and state “you have data acquisition system back it up”
I’m intrested in the data backing up the linear grip as the design is counterintuitive in that regards in to how you generate the extra 30% grip. I can appreciate you can’t have every thing and it’s ends up been a balancing act but good brakes are very high up my list of priority’s. If the taper is 1/2 the contact patch and the result is having to half the motor neg to compensate then it’s a prity big issue for me and I presume many others. I could be wrong in the air pocket allowing It the deform matching the road making a triangle contact patch have the complete opposite effect
On race cars camber is applied to the front wheels to compensate horizontal g force creating body role allowed by the suspension to flatten out the outside tire. Where the back drive wheels are kept prity flat to increase contact patch On a skateboard axle there is far less role as the axle is fixed with out suspension.
As for a unbiased testing this I’m unsure maybe a static load then uping the motor min (tho the ramp will have a large effect) of a vesc until you consistently lose traction and skid.
It was one of the reasons I was on the fence about buying the cloud wheels then thay had the hole core issues thay denied then refused to fix so stayed away.
