Inovative damping system from Staffanstaven for xc-poles and rollerski-poles to prepare them for summer using. Damps first forces with better feeling for ankles in arm and shoulder. Advantage of a light carbon pole with good power transfer and swinging but damping of forces like known from aluminum poles (without loosing grip and power). Made in Sweden incl. mounting instruction. One pair. Comes with carbon/kevlar. Medium damping (best choice of performance and comfort - other on request).
