SR SUNTOUR - OWNERS MANUAL
PRELOAD ADJUSTMENT / PERFORMANCE TUNING
SR SUNTOUR suspension seat posts can be tuned according to your personel weight, rid-
ing style and the terrain you are riding on, by adjusting the preload. It can be adjust-
ed to fit the needs of riders between 144 to 220 lbs (65 to 100kg). If you are less than
144lbs (65kg) or more than 220lbs (100kg) you have the possibility to replace the stan-
dard springs to a softer one (part no. PES004) or a harder one(part no. PES001).
The factory setting contains a medium spring(part no. PES004) and a hard spring (part
no. PES001) . To change to a softer setup, you have to replace the hard spring(PES001)
for an medium one (PES001).
If the SAG of your suspension seat post is too high (the saddle moves down and back) while you're
just sitting on your bike, you have to increase the preload of your seat post. A certain amount of
SAG is OK. We recommend an SAG between 0mm-10mm travel, but this is an individual setting
and depends as well on your weight, seating position and the terrain you are going to ride on.
Changing the preload will alter the SAG and breakaway force.
1. Remove the suspension seatpost off your
frame
2. To adjust the preload you have to turn
the adjuster bolt clockwise using a 6mm
Allen key.
3. Re-install and tighten with proper force
Do not turn the adjuster bolt counter-clockwise beyond the initial position at deliv-
ery. This can cause a failure to the preload adjuster bolt and can strip the threads. In
this original position, around 10mm of the seat post thread should be visible.

To asure a long life and a smooth function of your SR SUNTOUR suspension seat post it is neces-
sary to service your seatpost preriodically. Depending on the usage conditions and duration the
service intervals should be adjusted.
