my new mountain bike has a problem, when i try to start pedaling, the pedals turn freely without turning the front chain sprocket. is there something i need to tighten or do i need to send it back for a replacement?Just bought a new mountain bike and need advice?
Your sprocket isn't bolted to your crank arm. Take it back.Just bought a new mountain bike and need advice?
