Suits all AIM loggers and dash display/loggers, this potentiometer can be used to measure linear displacements like: Suspensions and spring cushions compression or extension Steering column rotation measured through the rack displacement. Shock and suspension travel Ride height Wing or spoiler deflection at speedAs a very simple guide - most bikes use 150mm on the front fork, 75mm on the rear shock and 50mm for the steering damper whilst most cars use 100mm on both the front and rear suspension.Please note: Supplied as standard with a 30cm cable.
