DIY Wheels - Hollow Wheels - Very Comfy

When I say grip, it is lateral grip. My bad. Obviously it is not going to generate extra grip on braking. I do have a DAQ, but its not like you’d trust my data without a video anyway - which is what I will go and create. Give me a week to make that video.

Yes and on race cars as well as any vehicle, the front wheels also have more camber. Weight also is transferred to the front of the wheels where most of the contact patch is needed. Brake bias is always front heavy. Moot Point on braking. On a skateboard, you have much more control over weight transfer as well.

Are you thinking that people are constantly doing skids when braking? It’s simply not the case and people on a mini road course do not complain. I have not had any beta testers give me feedback that braking is bad.

I’ll make a brake test video and put this to an end. It’s simply not a big of an issue that you think it is.

One last thought: If you’re considering the Cloud Wheels, but are only on the fence because of the core cracking issue, but aren’t concerned about braking just like you are on the Hollow Wheel, then I think you should consider this:

The Cloud Wheel is a much larger diameter wheel. Meaning, you will have less torque available for braking than you would with a 105mm wheel - assuming you’re not changing your gear ratio. If you were not thinking of changing your gear ratio, then this would definitely be the case.

The Cloud wheel is also significantly heavier as well. Coupled with the much larger diameter means that you will have much higher polar moment of inertia. This means it is harder to change direction. This means it is less responsive to braking input.

Finally, the Cloud Wheel has a tiny contact patch. Each rhomboid is 14mm wide (the very widest part). Picture attached. You can visibly see on my Cloud Wheel that the wheel contacts the ground with these almost-rhomboid looking things. It only touches the romboids and they are strangely offset. Picture attached.

I am not monitoring chatter about the Cloud Wheels, but I cannot recall anyone ever saying that they feel unsafe because it brakes like poop.

Blockquote[quote=“Darkie02, post:222, topic:38278”]
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.

Race cars always have more negative camber on the front because… when they go into a corner and they start slowing down for a corner, where do you think the weight goes? It transfer to the outside front corner (mostly) and outboard wheels as a whole. Rear wheels still have negative camber and are never. Never. Without any negative camber.

On a skateboard, you still have weight transfer. yes, it doesn’t have a traditional suspension as a car, but you can see the slow motion video for your very own eyes. There is still body roll and wheels are the suspension in a skateboard.

Both of these statements are generalized and erroneous.

Plenty of examples of “race cars” that do not.

I concede that you are correct in some cases

Was on the fence because of the contact patch and rough surface creating less grip on roads. refuse to use them because of the core cracking issue

So It appears you repeated what I said and we seeing it the same way now.

The other part I’m not sure about is the joining the 2 halves. Possible chunking, wobble, durability ect. But this is all new way of thinking and pushing new approach that I have no experience on or how it will react back up with your 500 mile warrantee. This part interested me most in the product and it’s out the box thinking. Only time will tell but I presume you looked and tested this part extensively and very confident

Who here lives in an incredibly hot climate with super crappy roads? I want to pay up to 3 people to put a shit load of miles on the production wheels and beat the living shit out of them.

DM me. Thanks, D

Hey all,

Update on the tooling. They are still in process with the tooling. Should be any day now. I am in constant communication with the factory. They’re running a little behind on the tooling but should be complete in the next week.

After this, they will produce a small batch for me to inspect and run accelerated durability testing on. After that passes, then it is off to mass production.

How’s the progress coming along?

Coming along. Still in progress with the tooling. Recently, it came to my attention that the Metroboard Kegel pulley had an interference, so I had to temporarily stop tooling to adjust the drawings and the mold. That was pretty scary.

i’ll be posting a complete update very shortly.

Luckily, it isn’t a drastic change. I’d say the big one is just going to be getting enough miles on the wheels before shipping because I want to be 100% confident that the injection molding is good. That and shipping and customs - there is always delays there, but hopefully I have enough buffer in the schedule that I am on time.

Great to hear it’s coming along as planned. Did you want to specifically support the metroboards pulley or was it just something that came up?

I will probably use the boardnamics pressfit pulleys for this since that’s what’s already on my TB110’s

I am also trying to workout a partnership with Metroboard too. I believe one of my beta testers has the Boardnamics pressfit pulleys. I think he had to kind of reduce the length of the studs tho because the studs go really far into the wheel, right? if you can send me dimensions of the pegs, I can tell you more

Do you have a STEP or anything? I have a legit copy (not stolen… learned that the hard way…) of 2015 SW; can’t open the file.

this work?

Thanks. That worked.

How does this pulley work?

Does it really have very sharp corners? It bottoms out on the the wheel? A steel part with a sharp part bottoms out on urethane?

This model is right?

There isn’t at least a big fillet at that edge?
