    How much PSI roughly should I add to my shock?

    A few days ago I poked the RS air shock I have on my fuel with an allen wrench just a bit to let some air out. At first I never sagged when I sat on it, but now it sags 25% and when it compresses, it wont come back up. My friend lent me his frame pump, so I'll be using that here soon. I need a rough estimate to achieve a 15%-20% sag upon sitting. Is something around 120ish psi right? I have no idea. Thanks for helping a newb.

    i was always tought to start with your riding weight(body weight plus clothes, bags, etc.) Ago from there, if it is too stiff take some out, and vice versa, i would check the maximum psi before attempting this.

    Just guess and check. Put about 150 PSI in see if its a good amount of sag. If not then add some or remove some. But yeah as already stated check the max psi.

    Have you read the manual for the shock?
    Do you own a shock pump?

    If you let all the air out and rode on it you may have really messed it up.
    Sag is set by measuring and adding/removing air as necessary.

    Edit: Here is your owners manual- http://www.sram.com/_media/techdocs/...bo_English.pdf
    It's only 4 pages... useful stuff.
