I need to buy a new shock absorber for my mountain bike. The current one has snapped in half. Before I do that I need to understand a bit more about how they work. I understand the spring bit 
. There is also damping, I'm guessing there is oil or air inside it which is squeezed through a small hole. What I don't understand is the knob marked "R" at one end. I assume it stands for "Rebound damping", but I can't see how it works. The shaft is hollow, is there an air valve in the end with the knob? Wouldn't that need a hole to the outside and wouldn't that get blocked with mud?
