Yellow Hub and Red Hub are the same.

I was talking to Egon and he said the only difference is that the cranks are different matterials. So ya, I dont know what else to say.

So he was saying that if you have a splined hub its more what cranks you have.

There are old and new designs of the red and the yellow one.
The new design is with ISIS and the old is splined (yellow) and square (red)
So not only the colour is enough to figure out what Hub you have
With implementing the ISIS Standard, the red hub becomes much better than before.

yes thats what I was thinking too I knew there were different ones. But ya.

Then why does UDC say

It is not suitable for serious jumping as only has lightweight ISIS hub and cranks, for extreme jumping look at our unicycles with splined hubs.

When did the Yellow ISIS hubs come out? and why can't I find them on UDC

The yellow hub is ISIS now also as you can read here
Maybe the single Hubs are still not on stock but they will be availiable for sure soon.
