It feels really good, i didn't notice much of an improvement until i put my old shock back on and its much better. It does have a bit more stiction as to be expected but i put some suspension spray on and its fine. I have the medium tune as i got it second hand, the voltage is recommended the low i think but i comes down to how you want it to feel.
Playfully, low bb means it corners and jumps really well, you do have to be a bit more choosy with you lines as it isn't a dh bike but its a really fun bike
