Inside, the Null includes a firm open-cell foam insert, providing enough support to maintain the tire's profile while allowing the tire to absorb bumps, cracks, and imperfections in the track with ease.
We've also been investing heavily in developing our own molded closed-cell foam inserts specifically for small scale tires. Expected to be available in November, these inserts are designed to provide even more precise tire support and consistency to take things to the absolute max.
