Carrying enough water on longer rides can be a problem, especially for touring cyclists where potable water sources are far apart. VO designed the Mojave cage to fit 32oz Nalgene bottles or 40oz Kleen Kanteen stainless steel bottles.
The mounting tab has 5 holes. This allows you to mount it in three positions, higher or lower as best fits your frame. You can also mount it on newer frames with three water bottle screw bosses. Construction is of all stainless steel.
One caveat, the Kleen Kanteen bottle is pretty tall, about 29cm with the sport top. It may not fit inside the main triangle of smaller frames. The Nalgene is shorter, but doesn't offer a sport top.
