Inside of hub part?
My brother bikes has messed up... I am sure it is the part inside the hub, what is this part called?
The problem is, when you try and pedal, it just doesn't move! The chain spins, and is on correctly, but the bike just doesn't move. Am I right about the part messing up? And how much would it cost? And what is it called??? It is only a cheapy bike, so we don't want to be paying out a load...
Just another random question, can I over tighten a quick release? I always make sure it is tight, but can I make it too tight?
I am only 14 so that is why I may seem a bit, well, a lot noobish...
Thanks in advance for any help, it would be much apreciated..
