I wonder what’s the darkest board you can make, no silver anywhere

Can you get black axles and bearings?

Vantablack everythanggggg.
Heat would be problematic.
I for one absolutely love dark mirror finish, maybe with some red or purple details, and spiked axel nuts.
Black bearings exist. Bushings can be dyed… ive got black wood stain and quartz sand on deck… now how do we color the axels themselves?

yes Trapstar,The outer shell is carbon fiber

Vantablack is an incredibly efficient “blackbody radiator” (infrared) and can easily shed itself of any (tiny) heating due to visible light absorption. In fact, Vantablack is so efficient that using it could result in a slightly lower overall temperature for whatever it is coating as long as that heat has somewhere to go.

Nice! I actually didnt know that, but its interesting.

So all heatsinks should be vantablack for efficiency?

An unnecessary expense IMHO. Just any flat paint or anodizing (doesn’t need to be black) can increase the terrible IR-emitting efficiency of a metal. But if the heat is just radiated onto other nearby things in an enclosure then you’re not doing much overall.

And if the heat sink has fins that are “facing” each other than each fin’s IR emissions will just be absorbed by the nearby fin. The shape of the heat sink is very important as radiative (infrared), convective (airflow, fan cooling), and conductive (connected to other metal) cooling all need a different shape/configuration for the heat sink.

The percentage of cooling possible via radiated heat loss, versus the other methods, might not be very high as it all depends on the setup. A polished metal heat sink will be lousy at cooling via radiation (emitting IR) but in lots of air flow it will be very effective at cooling via convection.

Makes sense. What about some kind of special, conductive paint?

The metal’s ability to emit IR won’t be affected by the electrical conductivity of the paint. Just any plain flat black paint will get you to within a percent or two of any specialized coating.

Look up “emissivity”. It’s the ability to emit IR. Metal has a low emissivity and so it’s crappy at getting rid of heat via radiating it. But metal has verrrry high thermal conductivity and can easily pass heat to something else that is well bonded to it (low thermal resistance between them).

If you paint metal then that great thermal conductivity passes heat into the paint. Since the flat black paint has very high emissivity it can then emit some heat away as IR radiation.

Whether this is just a tiny part of all the heat or much more depends on the particular setup. Some setups can benefit from increasing the emissivity of the heat sink. For other setups that will essentially do nothing.

I have 2 evolve GTR decks that both broke in that exact spot. Front snapped right off.

This is my fear with my Demonseed and Nemesis decks. It would suck to eat shit going +35mph just to get up and see your deck is also tattered

I used a few Rayne decks when I rode acoustic, they are much higher quality than the boat-wood evolve uses

I agree and is the main reason why I love Rayne decks. Fiberglass/composite construction is an absolute requirement.

For me atleast.

IMHO the biggest problems with the Demonseed deck are wheelbite, and the 44" variant no longer being produced. They seem to be built extremely well.

Risers and long hangers are a must with the Demonseed. My nemesis with BN220 on 1/2" soft risers wouldn’t bite on 120mm discovery CW. It was close with 6" pneumatics but never got it to bite. The Demonseed with 220’s on 12mm soft risers won’t bite CW but will on 6". I have some 270’s on the way and dost suspect any bite with those

I’m still riding dirty because Portland has no cops. :joy:

So you now you need insurance? I’m still hoping I can claim it’s a moped when I get pulled over.
