No More Bzzz.
Bontrager BzzzKill Barends adapt harmonic damper technology originally developed for professional archers and their high powered bows.
BzzzKill inserts are a simple and effective way to cancel high frequency road vibrations, and so improve comfort by reducing muscle fatigue, not to mention improving handling and performance efficiency.
The plugs are easy to fit directly into the end of the handlebar, and are available with a choice of brass or aluminium insert. Brass provides greater natural vibration damping properties, but weight in at 50g heavier per pair, so weight weanies out there might like to keep the extra grams to a minimum with the aluminium version.
