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 Suspension Tuner. Ditch the cheap o-ring or ruler and see precise, real-time percentages righ

Nice addition to my toolbox.
Bluetooth connectivity is great. App has lots of versatility. Just remember that you're measuring wheel travel and not shock travel so that you get correct data.

Fantastic product
It’s a brilliant idea to measure the vertical movement of the wheel rather than the seat. The three-piece design makes it perfect for transport and storage. The ‘Remove Before Flight’ strips are really cool! Slacker’s products are some of the best I’ve ever seen. 10 stars🌟

I love this for my bicycle too. So easy I check my sag, front and rear by myself. So easy to use
