"ORTLIEB products are characterized by tightly sealed closure systems such as roll closures, waterproof zippers, Velcro closure or sliding seal closures. "
"At Topeak, exciting new ideas for accessories are spinning at full speed and driving us ahead in a never ending cycle of innovation."
"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"
"Lezyne's mission is to create the most advanced and beautiful cycling products, ever. Bicycle hand pumps, floor pumps, digital pumps, shock pumps, multi-tools, tire repair, bags, bottle cages, CO2 inflators, tool kits, saddle bags, organizers, shop tools and more."
"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."
"Axiom is committed to helping cyclists ride more and live better, and we've been at it for 25 years. Our products are designed and tested by avid cyclists, so every minute detail is painstakingly considered before a final design is approved. The end result is a lineup of superior cycling accessories that meet the specific, everyday needs of people who ride bikes. Axiom means intuitive products, premium materials, innovative designs and cutting edge manufacturing techniques. We make cycling products that work, so cyclists have more time to play. Discover the world by bike."
"At Birzman, our mission is simple, keep riders riding, exploring and living boundlessly. In doing all we can to keep you riding, we make commitments: We are committed to producing tools that are more functionally efficient and durable. We are committed to producing tools that share the same pride of place as your bicycle."
Out on the trail and on the open road is where enthusiast, pro-teams and pro-riders get to experience the Birzman difference.
We define color as the main color of the item. It may have accents or highlights in other colors.
