I just got a brand new Sub Rosa Novus bmx bike and i rode it for the first time today. Everytime i landed with my back wheel from either a jump or a curb there was a metalic clinking/thudding coming from the rear end of my bike. Ccan some1 tell me what that is and if i need to have it fixed?
 
OK umm with bmx their is a little pin in the sprocket jumping probably nock it loose! sorry to tell you this but if clicking an thudding then your sprocket witch is the thing on your back rim thats sharp an the chain rides on ok that will start to screw up badly man! Just take it back an get a new back rim!
