Does what it says it does
I am a 240lbs rider that struggles to get sag set properly and still use most of the travel. I had no tokens 35% sag and still could not get to the last 30mm of a 170mm fork. First ride and i used more travel and had better mid stroke support. I was able to front wheel pivot on tight turns again.

Makes the fork react much better.
Smoother operation and I run ebike rockshox debonair gold rl’s 35’s. Without you notice the difference on my same trails. Great invention.
It didn't fit my air cap please note and made a 3d adapter that works great. I did buy another air cap for 35 lyric etc that screw was fine but advised not to swap top air caps.

Finally making the best out of my fox fork
I was struggling to find the best setup on my fox fit4 as with one token I could only use about 75% of the travel, while without volume spacers I would just burn mist of the travel most of the time. Trutune just solved that problem!
