    Jekyll Sag Indicator

    Hi Guys,

    Sorry for the stupid question in advance. But with the sag indicator do you set the pressure in the chambers to give the full 100% or something similar to 80% sag. I have tried the recommended for psi's from the chart supplied by Cannondale and they appear way to firm a ride. I weigh about 190-200lbs (90-92kg)
    Thanks

    Do you have a sag indicator fitted like the one in the picture below?



    Guessing for your weight, i would start by try setting your Positive pressure at about 320psi and your Negative at about 270 psi.

    If you have a sag indicator fitted you just want to indicator on the frame to line up with the Sag line on the fitted indicator.

    Remember that when you are un-screwing the pump due to the high pressures you can have a bit of air leakage, especially on the positive chamber, so you may have to compensate for this by adding a bit more pressure.

    Not with a good pump. Normally, the valve is shut before the pump's seal gets off, the air you hear coming out when un-screwing a pump (shock pump, tire pump) is the pressurized air that is inside the pump getting out, not from the shock. So if you always overpump by 5 PSI, you are riding with that additional 5 PSI. More air escaped when unscrewing the positive chamber because it has more pressure, so the inside of the pump has more air to release...

    I have no real idea if the Cannondale pump that's sold and comes with the bike for the DYAD is good or not, all i know is that air escapes from the the shock when i take it off, i know this for certain cause i have a digital pressure gauge used in professional engineering (aero, auto etc).

    Cheers both the sag indicator and the suggested range worked fine. It seems Cannondale/Fox have come up with settings about 2-3 weight levels too high. Well for me anyway.

    Cheers
