Static Sag and Rider Sag.

[robbo]

Just spent an hour or so reading UK and US suspension set up sites.The static sag figures seem to vary from site to site, anywhere from 20 to 30mm. Obviously your rider sag figure is the one that is imperative to achieve. As far as I can see the main point of static sag is to determine whether the spring rates are going to be up to the job, so if anything approaching half of the preload adjustment has been used up achieving static sag, then there's not much point in carrying on as the springs are too soft/knackered and it's time to spend more money :lol . Once you've attained the rider sag you're after, most sites I looked at suggested, with someone to hold the bike upright when it's on its wheels, to push down firmly to the rear of the filler cap(about the centre of the bike) and observe hopefully both ends of the bike returning to its static sag height at the same time, proving that the rebound damping speed is the same front and rear.
Well that's whiled away the afternoon. :rollin
