What Is a Tuned Mass Damper and Why Does Your MTB Need One?

This week, we’re diving deep into mountain bike innovation with Matt Shearn from Rimpact, a brand that started with tire inserts and is now making waves with cutting-edge technology. The Tuned Mass Damper, inspired by Formula One, promises to transform your ride, reducing vibrations and both mental and physical load. We’ll get into the science behind it, the testing process, what riders are saying and how I got on with the device. Plus, we’ll explore Rimpact’s chain damper and how it’s tackling drivetrain feedback to improve your ride even more. If you’re ready to hear what these game-changing technologies could mean for your ride, then it’s time to sit back, hit play and listen to this episode with Rimpact’s Matt Shearn.
