Description
This is the larger version of the container that mounts on the B-RAIL System. Designed to fit on your bike’s top tube (if you have mounting points!), it allows you to easily and quickly access items, even while riding. It’s perfect for storing snacks or other essentials.
For best results, use a 3 mm × 50 mm pin (DA025 from the Bambu store). If you prefer, you can also print the small pin in plastic — it’s included in the printing file.
About the B-RAIL System :
The B-RAIL System uses a mounting rail designed to fit any standard bottle cage mounts on your bike. It lets you attach a wide range of accessories and swap them out in seconds.
