Banjo Brothers

"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"

EVOC

"Over the last 20 years we have travelled to more than 50 destinations with our mountain bikes or snowboards, always searching for the best trails and greatest powder runs. We discovered fantastic places and found some amazing downhill runs. But what we couldn't find was equipment that met our needs. So, we began developing and producing equipment to meet our personal preferences: top-quality, sophisticated products with useful features."
