The pegs are aluminum which is bad for grinding. The frame is not 100% 4130 which means it isn't as strong. But, it is a great entry level flatland/all around bike. It will hold up to some mild street use as long as you keep things on it fairly tight.
The axles will very likely need to be replaced with a high quality Standard or Kink axle and you may opt for some steel pegs if you end up actually grinding a lot.
On the other hand, I ride my VERY short aluminum Ares Choise in parks and do some light grinding/stalls on aluminum pegs and it holds up fine.
