Strong, good looking, lighter than a lot of rims that are weaker than it.
Nothing. 17oz may be a bit much for weight weenies of which I am one, but still i have no desire to change mine.
I got this Rim used and have ridden it for over 2years now and only had to true it twice in this time. I ride street and park almost everyday and this thing hasn't given me a single problem. I am 100% satisfied with this Rim. I have it on my front wheel and do a lot of nose manuals/bonks/footjams and it just holds true. Also they look really sexy!
