Arundel's OtherSideloader Water Bottle Cage is pretty forthcoming in its name -- it's a side-loading bottle cage for those with non-dominant right hands. Since lefties tend to keep their dominant hand on the bars when reaching for water, Arundel flipped its ever-popular Sideloader design to accommodate. The cage is made from carbon fiber and weighs next to nothing. It has two sets of oversized mounting holes to ensure your bottle is precisely where you expect it to be.
