Review on Growler Grabber by Troy Robinson

Good quality, strong and excellent mounting point geometry. The cage itself is stretchable when the halves are separated, allowing it to accommodate more types of growlers (I recommend heat shrinking those arms). Unfortunately, while it fits my frame and fits even with the growler installed and leaves enough room to clear the cranks, it doesn't allow enough flexibility to insert the growler once the cage is attached to the factory bottle bar. I'll probably pass it on to a friend with a road bike.
