PERFORMANCE TUNING
RockShox Seat Posts can be tuned to your particular wei ht, ridin style, and the terrain you ride
on. Usin a medium bumper, our Seat Posts are set up for the 150 to 180 lb. (68 to 81 k ), all-
around rider. You may benefit from makin tunin adjustments for your specific needs. Install the
post and take your bicycle for a ride before makin any tunin adjustments. When tunin
suspension, always make one chan e at a time and write it down. Keepin a record lets you know
what chan es you have tried and su ests what chan es you mi ht try.
Setting Sag
The RockShox Seat Post is desi ned to compress (sa ) when you are sittin on the bike. The
optimum settin s for the best all around performance are 0 to 20mm sa for the MTB Post and 0
to 8mm sa for the Road Post. To measure sa , pull the dust boot up from the bottom and install
a zip tie on the inner tube so that it is flush a ainst the retainin rin ; sit on the bike in a normal
ridin position; then step off your bike and measure the bottom of the zip tie to the top of the
retainin rin . This measurement is the amount of sa .
NOTE: E SURE TO REMOVE THE ZIP TIE WHEN YOU ARE FINISHED MEASURING SAG.
Chan in the preload alters the sa and firmness of the initial post movement. The preload
adjuster plu in the bottom of the seat post tube adjusts the sa of the post (preload on the sprin
stack). When the preload adjuster is turned clockwise, the seat post will sa less and be firmer.
Turnin the preload adjuster plu counterclockwise causes the seat post to be softer and sa more.
Do not turn the preload adjuster plu exposin its threads at the bottom of the post tube. Failure
to observe this instruction could result in premature failure of the preload adjuster plu or outer
tube.
Changing the Spring Rate
Sprin rate chan es are made by cuttin the bumper. The followin are recommended elastomer
len ths for rider wei hts.
