"People ask, "Why Banjo Brothers?". The name was born over beers one night while we sketched photos of co-joined hillbilly twins while making "Deliverance" themed jokes. This is still our idea of a productive meeting. The point is, we probably weren't cut out for the cube farm.

We had a good name for the business but the niggling question was, "now what?" A trip to the local bike shop was the spark. On the shelf was a thinly-featured, over-priced, totally underwhelming seat bag. The rest kids, is history"
