Was lucky enough to score a prototype for my race bike. Free spirit frame, aftermarket square swingarm (mlm?), it still felt a little wobbly until adding this in. Bike feels very solid on the track with my 235lb ass on it. There’s some science about the hardness and all that I was informed in by the creator. All I know is it seems to help!
