"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"
"At Topeak, exciting new ideas for accessories are spinning at full speed and driving us ahead in a never ending cycle of innovation."
"ORTLIEB products are characterized by tightly sealed closure systems such as roll closures, waterproof zippers, Velcro closure or sliding seal closures. "
"Brooks England is steeped in history, a prestige brand that boasts almost 150 years of tradition and expertise. But quality and style never age. Do come in and take a seat."
"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."
"Our designs integrate countless hours of experience in the saddle and from tons of customer feedback. There's no better place than the open road to gather information. We listen and continually try to improve our saddlebags. We back our products with a no hassle warranty so you have peace of mind when you purchase Arkel."
"At Salsa, we believe a sense of adventure makes life better. The bicycle can be so much more than just a bike; it's a path to new places, new people, and amazing experiences."
