The Wald wire basket may be one of the best inventions since the bicycle. These are sold without mounting brackets or hardware so they can be zip-tied to the top of a front or rear rack.
This basket is a perfect size. It is strong and stable and can hold an amazing amount of stuff. When you don't need the basket, just cut the zip ties or use reusable zip ties. Because it sits on your rack it does not affect bike handling like a basket that is attached to your handlebars.
Practical and inexpensive. Pair with the Delta Cargo Net.
