well i have ridden with stock forks and also fairly decent chinese forks like the marzocchi replicas in mso sr's and these shit all over both of them, i havent rode with marzocchi shivers nor speed forks but id say these would be easily up there. I have a fox float shock in the rear of my bike and these front forks seem to perform just as good as the shock does so i rekon they are a good fork. When i bought them i was told that these are similar to the bombshells however they have much better dampening making them not near as pogo like, i havent rode with bombshells though to verify that...
