Welded rather than sewn seams are the only way to make 100% waterproof
backpacks.We WELD the seams of 210D nylon airline life vest fabric to create waterproof liners for our packs and panniers.
.These liners are then sewn into our packs using the welded tabs.
By using waterproof liners on the inside, we can give you more cycling specific features for your pack on the outside, like blinker mounts,pockets, pocket attachment points, compression straps and u-lock holsters. These liners also contain large welded velcro panels to attach padded laptop
These are replacement inner tubes which should be in every commuters repair kit. From 26" to 700c in both Schrader and Presta valves.
PRESTA VALVES: The Presta valve (also called Sclaverand valve or French valve) is a valve commonly found in high pressure road style and many mountain bicycle inner tubes and tubeless systems. It comprises an outer valve stem and an inner valve body. A lock nut to secure the stem at the wheel rim and a valve cap may also be present.
The Schrader valve (also called American valve) is a brand of pneumatic tire valve used on virtually every motor vehicle in the world today. The Schrader company, for which it was named, was founded in 1844 by August Schrader. The original Schrader valve design was patented in the United States in 1893. The Schrader valve consists of a valve stem into which a valve core is threaded, and is used on virtually all automobile tires and most wider rimmed bicycle tires. The valve core is a poppet valve assisted by a spring.
