Swenor Rollerski Damping Ferrules

Vibration damping rollerski tips with a few main diameters for poles! Check with your ski pole manufacturer to get the right size of tip for your pole. Most racing style poles are 8.5mm (which 9mm will be the one you choose) and lesser model poles are 10.0mm but some brands willl vary! Rather than a suspension system, these ferrules are made with a rubber layer in the innerworkings to help reduce vibrations on the road. Save your joints over long skis!
