Garage Files: How to Set Suspension Sag With Motool’s Slacker Digital Sag Scale

 

14. Pump the shock pressure back to your initial measurement.

15. Get back on your bike—it’s measurement time: You are now calculating sag in real time using the Slacker tool.

The math equation to calculate the shock stroke needed to obtain your target sag is: Total Travel X Target Sag (%) = Shock Stroke. Have a calculator nearby to confirm that the Shock Stroke value shown on the Slacker tool’s digital readout equals your Target Sag calculation.

—Remove all preload, and bottom out the suspension. Note: It may be necessary to remove the spring and mount just the shock body.

—Grabbing under the saddle, lift the rear wheel of the bike off the ground.

—Allow the rear wheel to drop/extend fully and zero out by pushing the power button once.

—Push on the saddle to bottom out the suspension.

The number displayed is total travel. Be sure to record this number (this only needs to be done once per bike).

—Preload the shock spring back to its initial measurement.

Note: It may be necessary to replace the spring, if removed.
