I just got a new Haro X5 BMX bike and i put it all together by myself (probably not my best idea) but i belive a cut the brake cable that you put the cable hanger on too short and i lost a piece to the cable hanger too, can I get new brakes for my bike? My brakes on there right now are Diatech magic 997 u-brakes. Also if you could look at the bike, can you tell me if I am tall enough for it? I am 5'4".
