i also ride a 2011 ex8 and agree with most of the others (with the exception of the giant frame ‘upgrade’ 😆 ) – i’ve changed nothing but the tires and the pedals. the stock tires suck if you do anything that isn’t paved.
but i would definitely not recommend dropping 5 feet on it! i’ve done some rock steps that push 2+ feet, but i don’t take them too fast. maybe it’s because i don’t have the nerves, but i’d like to think i am looking out for my bike 😃
