    SID XC air pressure question.

    Long time no post...I must have lost my old UN/PW...Oh well...

    Anyhow...My 2000 Mt. Tam has a SID XC fork. What is the recommended air pressure range for this fork?

    I can't seem to find any info at the RS site on a fork this old, so any tips on routine maintenance would be helpful as well. It doesn't seem to be leaky either oil or air-wise. How do I go about replacing the oil though, I'm sure it's due?

    Thanks,

    -Kev

    <120 lb rider weight= 30-40 PSI
    120-140 lb rider= 40-50 PSI
    140-160 lb rider= 50-60 PSI
    160-180 lb rider= 55-65 PSI
    >180 lb rider weight= 65-75 PSI

    Fat ass here at 225 pounds with a 2000 Sid XC. I ended up with 65 psi, so play around a little as the fork firms up very fast from 65-70psi. Don't know about routine service, but when my fork started to leak, the LBS sent it to rockshox who rebuilt the whole thing, tuned it, and updated all the seals and valves (2001 schrader valve now) for the whopping sum of $40.
    Riding slowly since 1977.
