The Titanium Iris Cage offers the same timeless design as our stainless steel version, precision-machined and hand welded in our Durango, CO shop. Crafted from solid titanium, this cage is incredibly strong and won't leave black marks on your bottle. It's a perfect fit for standard cycling bottles and also accommodates metal bottles like the Mover 18oz Purist, Kleen Kanteen, and Hydro Flask (with a bottom width of 2.9 inches). Thanks to its solid titanium material used (as opposed to hollow titanium or stainless steel), it weighs about the same as the stainless steel version. With a slightly tighter fit than a standard cage, it provides extra security, especially when mounted on the down tube. Like all of our cages, it's proudly made in the USA, combining top-notch craftsmanship with lasting performance. Specifications - 57 grams - Solid Titanium Rod - Stamped with 'King Cage Titanium' - Center of lower mounting hole to the bottom of cage: 30mm
