c-wa neilwrote a review of Black Diamond O2 Telemark Binding on January 21, 2011
I have been on these bindings for three years now and love them. I like the pivot point on these bindings way better than the Hammerheads. I currently have the rid-stiff springs on a pair of 188 LIB TECH Freerides and it is a great in-bounds setup. I don't use these ski's or bindings for my hiking setup. I have a lot of preload on the springs and haven't had a problem with springs coming loose. I know if you don't have the BD compression spring cartridges tight they do tend to give you problems...but then so would my pair of Rottefella Hot Chilis back in the day.
