So turns out you can create a similar system using closed cell air conditioning foam insulation, I've been riding on it for about a week and it feels great, about the same as all the claims about increasing damping and such. If anyone is interested in getting setup with a similar system to CushCore or Flat Tire Defender for under $15 as opposed at least $100 for those systems, let me know and I can create a DIY video. It seems to good to be true, and my DIY version may be 70% of what the big guys are producing, but if you can get 70% of the performance for about 12% of the cost, totally worth it.
