Garage Files: How to Set Suspension Sag With Motool’s Slacker Digital Sag Scale
DETERMINE YOUR TARGET SAG
Target sag is a percentage of the bike’s total travel. Most bike manufacturers recommend target sag for each specific model, so be sure to check the owner’s manual for your specific bike’s range of sag; however, there are a few rough guidelines based on the type of bike and riding:
XC bikes (≤120mm travel): 20–30% sag
Trail/enduro bikes (120–170mm travel): 25–35% sag
Downhill/freeride bikes (≥170mm travel): 30–40% sag
SETTING SAG USING THE SLACKER TOOL
The process of calculating sag is the same for the fork or shock. Motool provides a fork adapter, as well as a seatpost adapter, to facilitate rear-shock setup.
