I got the OG race wheel late 2018, and they were my main wheels until mid 2020 where they became dedicated short track wheels. And they finally gave up this June. Dont know how many miles I got on them. But a lot.
And I didnt really see or feel the wear. The cool thing is that they dont change charateristica when they are wearing down. They are slicks from new and they are slicks when they are worn completely down. But now when I look at them I can see that the rubber layer are thinner, but I feel the rubber layer still have miles in it.
What killed them was mainly the separation between the rubber and the foam. We saw that seperation when the wheel got hot. With normal use I didnt see any problems. But when using them on the short and long track where lateral forces are higher and there is a lot of acceleration and breaking. But I only experienced the seperation issue the last months of their life.
The seperation started on the lateral side of the wheels. It is also clear to see that its on the lateral side that they wear the most.
On the new wheels they use a “wrap around” config of the rubber on the lateral side. So hopefully that will protect that portion better.
These are close to being my favorit wheels I have tried up till now. And for me on for the short track they dont have a competitor. Maybe on painted cement there would be a more sticky rubber out there.
When you put lateral force into them, they are firmer than pneumatics. Especially if you run the pneumatics with less air to make the contact path bigger. Guess it’s like comparing a soft deck to a stiff deck when you want control.
Cruising around on the streets the lager MB won in the end for me because of a smoother ride. So I am really looking foreward to see how the new lager wheel will feel compared to the MB pneumatic.
I ordered a pair in 140mm. Just to be different 
and have the above things to test now that Brandon have done the “these are good enough to recommend” testing first. Will be fun.
Getting a grippy wheel that compares to pneumatics in smoothness but are firmer and can’t puncture, would be dream. Lets see…
