Voted as Dirt Bike Magazine's 25 Best Tools Ever Invented, the Sag Master is a tool that makes measuring Static "Race" Sag a snap because you read it directly. No subtracting!
The pin on the back of the Sag Master goes into the hollow rear axle. The tape measure gets extended up to a reference mark vertically above the axle.
When the rider is put on board and the suspension compresses you read sag directly.
Also useful in monitoring linkage and seal drag.
Doubles as a tape measure!
