DIY Wheels - Hollow Wheels - Very Comfy

This is on my to-do list to create a video, but also saving up money to make another mold change to fit longer kegel.

I apologize for the delay in responses. I am designing another version bigger of the Hollow Wheel and devoting all my resources and time toward that. I will make sure that I check this thread more regularly.

@JesseM, great to hear from you!

They are a much different material. The mold is the same. The material for Comfort and Pro uses separate compounds one optimized for grip and the other optimized for comfort. Please let me know if you have more questions.

That’s a lot of conjecture. I’ve had many bearings fail over the years, analog skating as well, and have never had parts of the wheel fly off… lol. Wheels with a single, solid, strong core, would keep everything together, but the wheel just wouldn’t rotate smoothly. If one is astute enough, they would notice and replace the bearing.

If the outer core takes no load, then why would the bearing fail?

So you are saying these wheels are designed to put all the load onto just the inner bearing? That sounds like a design flaw. Why would you purpose limit all the load onto 1 bearing per wheel?

@BallisticBullocks I did not say it doesn’t take zero load.

It is a design flaw if you do not account for factor of safety, yield stress, degradation of strength with respect to high heat and load, etc. Those loads and conditions were taken into account.

Moreover, the static and dynamic load limit of a single 608 2RS bearings are about 315lbs and 715lbs, respectively. Remember that load per wheel is distributed.

The load path is still in both of the bearings. The axial load from the nut, clamping in the bearing, also holds the cover on. You had a bad bearing and needed to be replaced. You are not the first person to ever have bearings fail. These things happen. Replace the bearings and move on.

The main point is that your bearing failed, as multiple people have said, and no wheel is going to have a good time when your bearing fails. Haven’t you seen some of the other catastrophes out there with failed bearings? You got off lightly

What brand of bearing were you using anyway?

These are dirt cheap shit bearings off amazon. I understand you guys wish to deflect and point fingers elsewhere. That is a fine tactic for the audience, but it’s not going to convince me. I have thousands of miles on these bearing with a few other wheels, even had a couple “fail” and I replace and move on. Just as you say to do now.

The thing is, A PART OF THE WHEEL FLEW OFF. That’s the issue. So, Doug, you are saying this is “as expected” and “normal”?

@BallisticBullocks I am offering you a replacement cover and some bearings.

When a bearing fails, the wheel (any wheel) will fall off. This is true of any wheel. No one is pointing fingers, but just sharing the physics of things.

Never did I say it is expected or normal for the cover to fly off. But when a bearing fails, any wheel in the world will fly off - the entire wheel. In this case, a part of the wheel fell off because the bearing failed. Wouldn’t you agree that when the outer bearing falls off, any other wheel would fall off too? If not, I can create a video demonstration for you.

I understand you’re angry and I acknowledge it. You spent some money on some wheels, you want to love them and I want you to love them as well, but now since you had a bearing failure, you are convinced that the wheel should have stayed intact. This is where we disagree because any wheel will fall off when a bearing fails.

I am offering a replacement cover and bearings and no refund as this was a bearing failure and it has nothing to do with the structure of the wheel. I don’t have to offer you the cover and bearings for free, but I want to in order to make you happy. But a refund is not eligible for this case.

Have a great day.

That’s completely insane. I’ve never had a wheel fall off from a failed bearing. You are insinuating it’s not just likely, but that it would always happen. Bizarre.

I’m actually not that angry at all at the wheel failing. Keep the wheel cover. Good luck with your wheels. Better luck to anyone else that chooses to use them.

???

The bearings are everything that keeps the wheel on. There is literally no other mechanism in a normal longboard wheel that keeps it in place, apart from the bearings. Tf you think is gonna happen when it breaks? Especially because

Take the L and move on.

Hi @BallisticBullocks,

This video is in no way to mock you but to explain my position on the matter. I am happy to conduct any other test you want me to.

I simulated the test using a Caguama with only the inside bearing installed. I put in bearing spacers to simulate a blown outer bearing. The wheel does fall off for me.

How besides luck is his hollow wheel staying on? How is your wheel fail safe?

I think you should have taken this offline and not dug a hole for yourself.

what bearings do you use? if you’re trying to be helpful of course.

How is any wheel fail safe when a bearing fails? Mike was expressing his dismay based on incorrect real-world scenarios and calling the Hollow Wheel flawed. I have to defend the design. I have nothing to hide.

Again, I offered free bearings and a cover to him to make him happy and to explain to him that a wheel will fall off when a bearing fails.

Always open to feedback. Thanks for contributing.

The test actually shows that the hollow wheel is arguably safer in the event that an outside bearing explodes. Nobody should expect a wheel to perform well when you use garbage bearings that are prone to exploding. Bearings are not the place to cheap out. If you don’t know what to buy, go with reds or zealous. Both are fine and cheap enough

608 2RS bearings. Steel ball bearings that I have purchased from my vendor. I am happy to send you a set.

I wasn’t asking you, but maybe you and shadowfax are the same person. I will just ghost this thread at this point. I’ll take the monetary and time loss. $140 on garbage isn’t as bad as talking chatting with you guys. Thanks for the great wheels Doug.

@BallisticBullocks

Sorry, I thought you were talking to me. It may be helpful to the @[insert name] thing. I can assure you that I’m not the same person as ShadowFox.

Sorry that you’re not happy, but your bearing failed and it is unreasonable expect a wheel or parts thereof to stay on the board when the bearing is what keeps the wheel on the board.

Lol detective Bullocks figured it out! Oh shit, bahahahahaha

You said you are using garbage bearings. I don’t know why you’re surprised they failed on you.

As @Evwan says “skill issue”.
