We have been using King brand bottle cages on our bikes for years. Ron Andrews is King Cage and he makes a standard style cage in stainless steel and titanium and the “Iris” cage in stainless steel. These cages are the bomb. They are light and strong and, unlike aluminum, they retain their spring so the bottles are always held securely and they won’t mark the bottles like aluminum. What I didn’t know before we saw him at the North American Handmade Bike Show in Austin earlier this year is that he makes every cage by hand, using a jig he designed and built.
