The Slacker Virtual Fender Mount provides the perfect attachment point directly above the rear axle to hook Slacker's retractable cable on. This lets MTB riders take 1:1 sag measurements across the entire suspension travel using a Slacker Digital Sag Scale. Ditch the cheap o-ring or ruler and see precise, real-time measurements, in millimeters, or the percentage of sag, right on the handlebars.
