On the road, one of the key contributors to fatigue is road vibration. Fight back and be more comfortable with Bontrager's Bzzzkill Harmonic Dampers. The Bzzzkill Dampers go inside your handlebar ends and utilize harmonic damper technology to cancel high-frequency vibrations. The dampers work by isolating a weight within an elastomer web. As vibration travels through the handlebars, the elastomer delays oscillation of the weights effectively canceling vibration, leaving you fresher and letting you ride longer.
