Never lose a bottle again with these incredible titanium bottle cages. This lightweight design doesn&';t mark your bottles, allows easy access, and holds your bottles on the worst terrain. The tubular titanium construction and other design characteristics produce a cage that has better retention on gravel and other harsh surfaces and has proven to be the superior design when mounted on the underside of the down tube, so common in adventure riding and touring.
