Widefoot, makers of the Liter Cage, now offer their Nalgene-friendly bottle cages in a black powdercoat finish, for those of you who prefer black components, to silver. I used these on my Hunter in South Africa, toting two, 1.5L Nalgenes on 115 miles of washboarded desert roads during the Karoobaix without issue. I do however recommend using one of their multistraps to keep the bottles from popping out on descents. Check out the Blackened Liter Cage at Widefoot!
