Alex B.wrote a review of Black Diamond O1 Telemark Ski Binding on January 4, 2011
Tour mode is so easy.. get rid stiff if you're agressive and/or ride fat boards. Duct Tape the cartridges to prevent the anoying problem of them loosening on their own.. Lots of touring an no break downs. Ski great and very powerful. Never pulled out of skis like some have complained about. Broken heal blocks? No issues. I also have 22 designs Hammerheads.. I like them very much.. about the same going down hill, but no tour mode.
