    Cannondale has an app for that. It's called "Cannondale Tune Your Ride". FYI, for a 185 pound rider with 10 pounds of kit, and 2013 Lefty Alloy 2 with the alloy PBR fork, the app recommends 130 psig and 25mm sag, +/- 2mm.

    2012 flash 2 lefty air pressure settings.

    I'm riding my 2013 fork ~10psig higher than spec, so working down from 150psig will probably dial it in for you. My advice is check the sag before riding and the o-ring position (for full travel) afterwards, and ensure you are using your full travel but still at slightly higher pressure, and you will find the sweet spot.

    You need to read your owner's manual.

    There's an o-ring around your fork ... sit on your bike geared up, in a neutral weighting, and then get off very lightly/gently, and measure the travel distance. Maybe make a few trials ... don't add compression from bouncing on or off.

    The distance of compression travel ...That's sag.

    Not on the OP's 2012 fork. To check sag I just note where the handlebar hits against the wall unloaded and then when I get my weight on the bike.

    Thanks but to get the proper sag you have to let air out of the fork right?..

    Unless of course you don't have enough air and there's already too much sag, right? From my experience the Cannondale app gave me pressures too low and I had too much sag so I increased pressure until I got the minimum amount of sag.
