Looked at the Scrub site. Didn't have any hardness values. Without hardness ratings, there's no way to know for sure.
Edit: I have heard eggs referred to as urethane elastomers. Who knows. Don't think they're rubber.

i'm almost certain they're a hard urethane compound. The yellow ones feel very similar to a urethane suspension bush in a car and i know you can get harder ones. I would be carefull buying rubber ones as rubber is no where near as durable as urethane so you may be saving money now but having to buy a new set in half the time. I love my trampa dampas 

I live life a quater mile at a time. And when i'm not doing that i'm riding my mountain board.

For you MBS riders that ride Matrix Lites and think they are still too loose. I suspect you can make those bad bears rock hard with GI red eggs.
Was playing around with my Razor-Wides test rig. Decided maybe try red GI rear and green GI front, springs at the inside position. Set it up and did a little test rocking back and forth -- way too stiff for surf-style.
Putting GI reds all the way around on Matrix Lites would be really stiff -- might even be able to make Mx Lites springless with an extra washer or two.

durometer ratings are only comparable if a very similar compund is being used. Durometer (shore) ratings of skate wheels is next to useless when comparing how firm they feel in the real world. I assume egg shocks are made of pretty similar compunds and the science hasn't yet got too technical but i would still be wary of relying solely on a figure derived from effectively shoving the end of a blunt nail on a spring into them.

They are made of urethane. How similar the products are, I can't say.
But in the absence of other information, all we have is the durometer rating for comparisons. And this data was hard to dig up.
Also, the shape makes a difference too. You can't really compare Trampa's and GI's with MBS because the Dampas and former GI eggs/elastomers were taller -- more material less space for compression. But I needed some limited information for comparison and selection. It is a starting point.
