How can u tell if your fork is an air fork or a coil spring? I'm wondering on one of my RST's and i can't tell if its an air of spring. i want to know becuase i want to know if i need to buy a shock pump in the future. Do any of you know how to tell which is which?

You can buy one but you cant use it with this fork. Because if you read what I posted you would see that it is NOT an air fork

you asked if you can buy one. you can buy ANYTHING. but in this case, you wont be able to put that pump to use with that shock because its a SPRING absorption. meaning NO AIR.

OK,
Left over MC days stuff hear, but ALL fork are air forks to some extent.
There is air in the chamber, when the fork compresses the air does too.
But since this has elastomers, it probably does NOT have oil, and as such may not be sealed.

If it has oil, and is then sealed, you can add air valves to the caps and add a LITTLE air to help the springs.

Might not work on a cheaper (I don't know what price point your fork is) bike fork.
