The Triple Bob rail provides a convenient and secure means of attaching a Hailong-1, 21700, and Reention case Downtube battery to any location on the bicycle frame tubing regardless of the eyelet position.
These pieces are CNC machined from solid aluminum stock and provide a wide and flat platform for the battery cradle to rest, secured with three M5 bolts so there is none of the rocking or play that is sometimes present with waterbottle eyelets.
