Steps 1 and 2 can be completed at home.
For half bags, we recommend the Wolf-Tooth B-Rad 2 and/or a Lowering Cage if bottles are high up. This maximizes bag space. Let us know if you plan on getting this, and we can digitally simulate it.
We like these smaller 22oz Purist bottles for half bags.
Super!
