Of course its more sporting to climb without leashes. Leashes are really important, particularly in Alpine areas, where loosing ice tools could lead to disaster and conserving energy is significant. The Leash Clamp by Edelrid provides a way to retrofit ice tools and ice picks with a leash attachment. The Leash Clamps are perfect for using with the Edelrid Leash Extreme Set or similar clip leashes. In addition to the Rage, Riot and Raid ice tools, the Ronin and Race ice picks can also be retrofitted perfect for pulling yourself up the ice.
