The Good: lightweight- this thing is a feather
plush- quite responsive
The Bad: these things break so easilly!!!!! At rays mtb park they had 831s on every rental bike. by the end of the year... every one was broken. Ive seen a guy go off a jump and the lowers separated in the air. frankly im a little scared to ride a fork like that. fox says you need to get them serviced every 40 hours of riding! no thank you. ill pick up a circus.
unless your a world cup mechanic who can service this thing after every ride i wouldn't take this in the interest of my own well being. There cool for sure and work great... until they break. you decide
