I bought a pair of Karhu Jax skis with the Garmont 7tm Power releasable Telemark binding and after using them once I noticed that the left binding has a "removable power pin" and the right one does not.
(a) Do these pins fall out by themselves sometimes (which seems highly unlikely)?
(b) Where can I purchase spare parts?
