Why? He loves his! "I have a hifi. I love it! at first I was a bit worried I had made the wrong desision as I couldnt do squat on it. I am now a bit more used to it (not fully yet), I still cant tap for shit, but gaps, sidehops and riding natural rules!! It is really stable on the rear, setting up for a sidehop on a pointy rock is no problem. I can also manual and bunnyhop this bike easier than I could on my 1065 pure. It is also a very light frame, my bike weighs about 22lbs, but its also the stiffest frame I have ridden. I highly reccomend this frame to anyone, its amazing!" http://www.observedtrials.net/vb/showthrea...light=echo+hifi
