got my bike

i got my new bmx bike in the mail i built the whole bike then i was about to put the pedals in and i found that the cranks had metal poured in it and my pedal wont go in so im taking it ti the shop to get fixed or i might just order some cheap replacement cranks . Also dans comp sent me the wrong sprocket and stem instead of being black it was navy blue !! its not that big of a deal but ill probably get a new stem and sprocket anyways . so ya!
