i've been riding bikes for my whole life - freestyle, bmx, vert, road racing, triathlon, mtb (downhill, super-d, cross-country), freeride, gpv, you get the picture.
I have never broken a frame. as long as a bike frame is built reasonably well, you shouldn't break it. if you have a problem w/ snapping frames, i'd take a look at your riding style/skills. think "smooth" and "flow"....
i've had my moment for about 6 months now and it is by far the best suspension bike i have ever ridden (in the past, my stable has included a v10, enduro pro, and a dirtbag). it's so good, i'm seriously thinking about ditching the dirtbag.
the moment is absolutely amazing.
