If your racing competitively daily, its not for you!
Unless you weigh your shoes,keys, cell phone, wallet,sunglasses, mp3 player, etc... before you ride, i wouldnt worry about the "lil" extra weight,in this case,its worth it in looks, laughs, etc..

 haha good how much weight??

 They say 506 gram on the net, i dont have a scale however...
