If you are purchasing bottle holders, go with the cheaper metal bottle cages for functionality. They may not look as good but they do the intended job much better.
ConsNot as functional as normal metal tube bottle holders. The plastic doesn't stretch well and can't be adjusted to bottle width.
i would recommend this. It is a nice bottle holder for shorter rides. you would probably want to invest in a camelback for the longer trips.
ProsSturdy,light weight and you barely know it is there
Conshave to buy a certain bottle for it to fit.
