Let's say we've got this unique tandem design and we've mounted a water bottle on the stoker's top tube. In earlier versions of BikeCAD, we've had the ability to toggle which side of the tube the bottle is mounted on, but the bottle would always be pointed in the same direction. In BikeCAD version 20.5, instead of toggling through three different states, we now toggle through six. In the additional three states, the bottle is pointed in the opposite direction. Useful for unconventional frame configurations such as this.
